hugocasa c28314f424 feat: runner groups for shared-process multi-script dedicated workers (#8434)
* feat: add runner groups for shared-process multi-script dedicated workers

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: unify dedicated worker and runner group wrappers into single multi-script wrapper

Replace per-language single-script wrappers with the unified load/exec/exec_preprocess/end
protocol. Each start_worker() now writes scripts to scripts/<safe_name>/ and uses
generate_multi_script_wrapper(). handle_dedicated_process() sends load: on start and
exec: per job instead of raw JSON args.

* chore: update ee-repo-ref to match EE branch

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: gate EE-only functions behind cfg(feature = "private") to fix OSS dead_code errors

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: auto-detect runner groups from workspace dependency annotations

- New endpoint GET /scripts/list_dedicated_with_deps: returns dedicated
  scripts with parsed workspace dependency names from content annotations
- Frontend: show dep badges in DedicatedWorkersSelector with links to
  workspace settings, warn when referenced dep doesn't exist, group
  scripts sharing deps into "Shared runner" sections
- Remove manual "Runner groups" tab and RunnerGroupSelector component
- Remove runner_groups from WorkerConfigOpt/WorkerConfig (auto-detected)
- Fix Node.js single dedicated workers: transpile main.ts -> main.js via
  Bun.build so the multi-script wrapper's dynamic import() works under Node
- Add package.json with type:module in scripts dir to silence Node warning

* refactor: unify dedicated worker wrappers with baked-in codegen and routing

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: update ee-repo-ref

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add e2e tests for multi-script dedicated worker routing (bun, deno, python)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: remove dead generate_dedicated_worker_wrapper function

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add dependency installation to runner groups + make dep functions pub(crate)

* chore: update ee-repo-ref

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: update ee-repo-ref

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: prevent bun loader from intercepting absolute paths within cwd

When a plugin's onResolve returns an absolute path, Bun re-invokes
the resolver with that path. The loader was then routing it through
the remote URL resolver, breaking runner group script imports.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use _wm_ prefix for runner group scripts to avoid bun loader interception

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: update ee-repo-ref

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: extract DENO_UNSTABLE_ARGS constant to avoid repeating flags

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: regenerate system prompts

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: gate private-only exports behind cfg(feature = "private") for OSS build

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: move format strings before handle_dedicated_process to fix lifetime

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: regenerate sqlx offline cache

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix sqlx

* fix: skip empty lines in deno e2e tests (double newline from console.log + '\n')

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use dict() instead of {{}} in python wrapper to avoid set literal

{{{{}}}} in format!() produces {{}} which Python interprets as an
empty set, not a dict. Use dict() which is unambiguous.

* refactor: remove deno from runner groups and associated tests

Deno resolves dependencies at runtime via URLs/import maps, so there's
no shared node_modules/pip install to benefit from runner groups.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: revert deno wrapper to inline old-style with exec: protocol

Since deno doesn't support runner groups, the unified multi-script
wrapper is unnecessary. Reverted to the old inline wrapper from main
but adapted to use the exec:<path>:<args> protocol.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: extract deno wrapper into reusable function and add e2e tests

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use codebase presence (not nodejs annotation) to determine wrapper import extension

On main, codebase scripts import ./main.js (pre-bundled JS).
The wrapper_ext was incorrectly based on annotation.nodejs.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: improve dedicated workers UI - combine lists, better badges, tooltips

- Merge shared runners section with selected tags into one unified list
- Move language tag to right side of selector for alignment
- Change dep badge color from dark-gray to indigo
- Add tooltip on yellow warning badge explaining missing workspace dep

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: group shared runners visually in dedicated workers list

- Runner groups shown with a header (Shared runner · language · dep badge)
- Scripts in the same group nested under the header
- Standalone scripts/flows shown after groups
- Used Svelte snippet for reusable tag row rendering

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: improve visual separation between shared runner groups and standalone items

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: give standalone runners same header style as shared runners

- Each standalone script/flow gets its own header row with bg-surface-secondary
- Header shows "Dedicated runner" / "Flow runner" label, dep link, language badge
- Shared runner header: swapped language and dep badge positions
- Dep shown as inline link instead of badge in headers for cleaner look

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: inline standalone runner path in header, language badge on right edge, no max height

- Standalone items: path shown directly in header row (no sub-row)
- Language badge placed after flex-1 spacer (right-aligned)
- Removed max-h-64 overflow constraint from the list

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: consistent badges across runner list - dep+language on right, depBadge snippet

- Shared runner scripts: show (workspace) and language badge on right
- Standalone items: dep badges and language badge on right (after flex-1)
- Shared runner header: dep badge and language badge on right
- Extract depBadge snippet to deduplicate dep badge rendering
- Picker selector also uses depBadge snippet

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: show language badge on standalone items, hide from shared runner sub-items

- Fetch script language from API when not available from workspace deps
- Hide dep+language badges from tagRow when script is inside a runner group
  (already shown in the group header)
- Standalone items now always show language badge

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: differentiate badge colors - gray for language, indigo for workspace deps

Matches codebase convention: gray for metadata (like script hashes),
indigo for linkable features/entities.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use transparent (bordered) badge for language - visible on all backgrounds

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use gray badge for language everywhere

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: revert skills.ts and AI files, add _wm_ exclusion to Windows loader

- Revert cli/src/guidance/skills.ts to main (not our change)
- Revert AI provider formatting changes (not our change)
- Add _wm_ prefix exclusion to loader.bun.windows.js filterResolve

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: update ee-repo-ref and regenerate system prompts after merge

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* perf: use DISTINCT ON in list_dedicated_with_deps to dedup at DB level

Avoids fetching all script versions and deduplicating in Rust.
Addresses PR review feedback.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use sqlx query! macro for list_dedicated_with_deps and regenerate cache

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: dedicated worker review fixes and test coverage

- Fix Python relative imports in dedicated workers (write loader.py, add
  import loader to wrapper when needed)
- Move Python colon parsing inside try/except to prevent crashes on
  malformed stdin
- Add indexOf guard in Bun/Deno wrappers for malformed protocol messages
- Add stderr logging for unrecognized stdin commands in all wrappers
- Remove asyncio handling from Python wrapper (consistent with normal path)
- Add exec_preprocess protocol tests for Bun, Deno, and Python
- Add argument transformation tests (dates, bytes, kwargs, sentinel)
- Add relative import detection test for Python wrapper
- Add PreprocessedArgs variant to DedicatedWorkerResult test helper

* fix: remove symlink from git and gate has_relative_imports behind private feature

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: update ee-repo-ref for dedicated_worker_ee.rs changes

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add mixed exec+preprocess test to use ProtocolCmd::Exec variant

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: remove hanging deno missing-preprocessor test

The Deno wrapper only generates the exec_preprocess handler when the
script has a preprocessor function. Without one, the message is
unrecognized and the test hangs reading stdout.
