* feat(plugins): build-less TypeScript workers
A worker's main may be .ts/.mts. The plugin host installs module.registerHooks scoped to the
plugin folder: .ts files are transpiled with the frames' sucrase options (lines kept, inline
source map, source maps on), relative imports fall back to the frames' candidate files, and a
value import of the type-only 'orca/worker' fails with a clear error. Needs engines.orca
>=1.4.246.
* feat(plugins): components panels hot reload with their state
- In dev folders a save swaps only the hidden guest: keyed memory atoms are handed to the new
guest (ui.retain → ui.hydrate memory), dropped when an atom's version changes.
- A save that fails to load keeps the last good render and shows an inline file:line:col
error banner; the next good save clears it. A subtle Reloaded mark follows a reload.
- Transpile and import errors carry line and column; dev worker restarts keep storage.
* feat(plugins): orca plugin dev watch
One command for the inner loop: refreshes .orca/types, dev-loads the folder, follows its frame
and worker logs (plugins.getLogs gains an optional cursor), prints reloads (optional
devChangeCount on list entries) and status changes, and unloads on Ctrl-C. --json streams
NDJSON events for agents.
* feat(skills): orca-plugin-authoring bundled skill guide
A guide for agents to build Orca plugins end to end (decision table, build-less rules, the
dev watch loop, test/check, validate, release-entry, approvals, gotchas) with references
generated from the component catalog, host API table, event schemas, manifest schema and CLI
specs, checked for drift. Fixes the components template's Reset to set(count, 0).
* feat(plugins): orca plugin dev watch --check; test kit details in the authoring skill
- --check runs orca plugin check after the load and after each reload (one at a time; saves
made meanwhile fold into one rerun) and prints each panel's render or errors inline, as a
`check` event with --json. Local folders only, since it runs the plugin's code here.
- The orca-plugin-authoring guide's Test and check section now documents orca plugin test and
check from #36969 exactly (JSON results, exit codes, test placement, the orca/testing kit and
its common mistakes), and the loop uses dev watch --check.
* refactor(plugins): move the components renderer's timing and helper constants to their own module
