bundle-analysis

Read `packages/tools/bundle/README.md`, then select one workflow: - **Stable comparison:** `pnpm bundle-compare <base-ref>`. Use `HEAD~1` for the latest commit. Read `tmp/bundle-stats.txt` and report non-zero differences. - **Selected comparison:** `pnpm bundle-compare-selected --base <ref> scratchpad/<fixture>.ts`. Use only user-named or investigation-local fixtures; keep temporary fixtures out of the stable corpus. - **Composition:** `pnpm bundle-analyze scratchpad/<fixture>.ts`. Read raw data first and report the largest modules, dependency groups, and surprising inclusions. Its readable-name output is not an exact size measurement. - **Current size:** Build immediately before the direct bundle report so Effect packages resolve from current `dist` output. - **Cleanup:** Stable comparisons retain `tmp/bundle-base` for reuse unless cleanup is requested. Remove selected-comparison state retained with `--keep-base` after its final use. Verify cleanup without disturbing unrelated worktrees. The task is complete when the selected artifact is inspected, requested size or composition findings are reported, generated paths are named, and comparison state follows the selected workflow's retention policy.
