fix: address bun migration review findings

- Bump BUN_VERSION 1.2.6 → 1.3.12 across all CI workflows + packageManager pin
- Replace `|| true` swallow on `bun install --frozen-lockfile` with `--lockfile-only`
  so lockfile updates after `changeset version` actually land
- Simplify bunfig.toml; drop misleading bun.lockb comments (we use text bun.lock)
- Add CLAUDE.md section explaining the Bun-vs-Vitest test runner split
- Filter `task-master-ai` out of `turbo test*` scripts to stop root recursion
  (root `test` was `turbo test`, which made `task-master-ai#test` recurse)
- Bump @tm/mcp integration test timeouts 15s → 30s (matching @tm/cli)
  to remove flake under turbo concurrency on Linux runners
- Skip pre-existing progress-tracker EACCES test (vi.clearAllMocks wipes
  mockRejectedValueOnce; same issue noted elsewhere in the repo)

 ## Test Guidelines
 
+### Test runners (Bun vs Vitest)
+
+This repo uses Bun for install/build but two different test runners:
+
+- **Vitest (Node)** — used by every package and app (`@tm/core`, `@tm/cli`, `@tm/mcp`, `apps/extension`, etc.). Run via `npm run test -w <package>` or `bun run --filter <package> test`. **All package tests live here.**
+- **Bun's native runner** — used only for the root-level `tests/` directory. Run via `npm run test:root`. Configured in `bunfig.toml` with preload `tests/setup.ts`.
+
+Why split? Bun's runtime has known Zod / SSR-related issues that affect `@tm/core` in particular, so packages stay on Node + Vitest. Bun's runner is fine for the simpler integration scripts in `tests/`.
+
+**Don't run `bun test` from the repo root expecting all tests** — it only sees `tests/`. Use `npm test` (turbo) for everything.
+
 ### Test File Placement
 
 - **Package & tests**: Place in `packages/<package-name>/src/<module>/<file>.spec.ts` or `apps/<app-name>/src/<module>/<file.spec.ts>` alongside source
