NeilandOrca f311307560 Add max-lines ratchet CI gate to block new line-limit bypasses (#7608)
oxlint already fails any file over max-lines that is not suppressed, so the
only way to grow past the budget is to add an eslint/oxlint-disable max-lines
comment or a per-file max-lines bump in mobile/.oxlintrc.json. This adds a CI
gate that freezes the current set of suppressions (config/max-lines-baseline.txt,
355 grandfathered entries) and fails the build when a NEW one appears — with a
loud, actionable message pointing at 'split the file'. Existing oversized files
are untouched; the baseline may only shrink (pnpm check:max-lines-ratchet --prune).

Wired into the root lint script and as a dedicated pr.yml step. Unit-tested
(15 cases) and verified against all three failure paths + clean-tree pass.

# AGENTS.md
## Design System
All UI work — layout, color, typography, spacing, component selection, UX behavior — must follow [`docs/STYLEGUIDE.md`](./docs/STYLEGUIDE.md). Use the tokens defined in `src/renderer/src/assets/main.css` (the canonical source) and the shadcn primitives in `src/renderer/src/components/ui/`. Don't invent new color values, font sizes, or shadow tiers when a documented one already covers the role. When STYLEGUIDE.md is silent, follow the resolution order in its final section.
## Code Comments: Document the "Why", Briefly
When writing or modifying code driven by a design doc or non-obvious constraint, add a comment explaining **why** the code behaves the way it does.
Keep comments short — one or two lines. Capture only the non-obvious reason (safety constraint, compatibility shim, design-doc rule). Don't restate what the code does, narrate the mechanism, cite design-doc sections verbatim, or explain adjacent API choices unless they're the point.
## Lint Rules: Do Not Disable Max Lines
Never add a `max-lines` disable (`eslint-disable max-lines`, `oxlint-disable max-lines`, or line-specific variants), and never add a per-file `max-lines` bump in `mobile/.oxlintrc.json`. Split the file, extract focused modules, move fixtures/builders into named files, or otherwise reduce the counted lines instead.
This is enforced in CI by `pnpm check:max-lines-ratchet` (`config/scripts/check-max-lines-ratchet.mjs`). Files already over the limit are grandfathered in `config/max-lines-baseline.txt`; that list may only **shrink**. Adding a new suppression fails the build. If you remove a suppression (great — split it!), run `pnpm check:max-lines-ratchet --prune` to drop its baseline line.
## File and Module Naming
Never use vague names like `helpers`, `utils`, `common`, `misc`, or `shared-stuff` for files, folders, or modules. They carry zero info and tend to become dumping grounds. Name files after what they _actually_ contain — prefer the concrete domain concept (e.g. `tab-group-state.ts`, `terminal-orphan-cleanup.ts`) over the generic role (`tabs-helpers.ts`, `terminal-utils.ts`). If you find yourself reaching for `helpers`, the file probably has more than one responsibility and should be split, or there's a better name hiding in the code that describes what the functions operate on.
## Worktree Safety
Always use the primary working directory (the worktree) for all file reads and edits. Never follow absolute paths from subagent results that point to the main repo.
## Cross-Platform Support
Orca targets macOS, Linux, and Windows. Keep all platform-dependent behavior behind runtime checks:
- **Keyboard shortcuts**: Never hardcode `e.metaKey`. Use a platform check (`navigator.userAgent.includes('Mac')`) to pick `metaKey` on Mac and `ctrlKey` on Linux/Windows. Electron menu accelerators should use `CmdOrCtrl`.
- **Shortcut labels in UI**: Display `⌘` / `⇧` on Mac and `Ctrl+` / `Shift+` on other platforms.
- **File paths**: Use `path.join` or Electron/Node path utilities — never assume `/` or `\`.
## SSH Use Case
All changes must consider the SSH use case. Don't assume local-only execution.
## Git Provider Compatibility
Source-control and review changes must consider GitLab and other supported git providers, not only GitHub. Keep provider-specific behavior behind explicit checks, and avoid GitHub-only naming for generic review concepts.
## GitHub CLI Usage
Be mindful of the user's `gh` CLI API rate limit — batch requests where possible and avoid unnecessary calls. All code, commands, and scripts must be compatible with macOS, Linux, and Windows.
Never commit PR evidence images; attach them to the PR conversation instead (but never use gh-attach).
## Type Declarations: Prefer `.ts` Over `.d.ts`
