[sedge-bot]

Summary

• Link bat in the README app table
• Keep generated README.md in sync with templates/README.md.tmpl

Closes #6

Test Plan

• python3 tools/build.py
• python3 -m py_compile tools/build.py tools/lib/*.py
• git diff --check

Sedge verification for the current head (006ecd2):

• git fetch github main --prune ✅
• python3 tools/build.py ✅
• python3 -m py_compile tools/build.py tools/lib/*.py ✅
• git diff --check github/main..HEAD ✅

The PR is docs/template-only (README.md, templates/README.md.tmpl) and the local clone is clean after regeneration. GitHub still reports mergeStateStatus=UNSTABLE with no statusCheckRollup entries surfaced, but I don't see a local verification blocker.

Heartbeat re-verification at 006ecd2 (2026-05-16):

• GitHub still reports state=OPEN, mergeable=MERGEABLE, mergeStateStatus=UNSTABLE, with no surfaced checks in statusCheckRollup.
• Fetched current github/main and confirmed the PR diff is still scoped to README.md and templates/README.md.tmpl.
• Local gates passed:
  • python3 tools/build.py
  • python3 -m py_compile tools/build.py tools/lib/*.py
  • git diff --check github/main..HEAD
• Clone status was clean after verification.

No local code/docs blocker found; this still looks ready for maintainer review/merge despite GitHub's UNSTABLE merge-state label.

Re-verified at head 006ecd2398fa97161dca0a420e097003f436befe for the README tool-link docs diff (README.md + templates/README.md.tmpl). Local gates passed:\n\n- python3 tools/build.py\n- python3 -m py_compile tools/build.py tools/lib/*.py\n- npm ci --prefix packages/vscode-extension --ignore-scripts --audit=false --fund=false\n- npm run compile --prefix packages/vscode-extension\n- git diff --check github/main..HEAD\n\nGitHub still reports OPEN / MERGEABLE / UNSTABLE with an empty statusCheckRollup, so I do not see a code-side failing check surfaced for this docs-only PR.
