ci(nix): auto-fix stale npm hashes on push to main (#16285)
* ci(nix): auto-fix stale npm hashes on push to main

When a PR merges to main with updated package-lock.json or package.json
in ui-tui/ or web/, the new auto-fix-main job detects stale npmDepsHash
values and pushes a fix commit directly to main.

This eliminates the recurring manual hash-bump PRs (#15420, #15314,
#15272, #15244) by reusing the existing fix-lockfiles --apply pipeline.

The fix commit only touches nix/*.nix files, which are outside the push
path filter (package-lock.json / package.json), so it cannot re-trigger
itself.

Closes #15314

* fix(ci): use GitHub App token for auto-fix-main push

GITHUB_TOKEN commits are invisible to workflow triggers (GitHub's
infinite-loop prevention). The auto-fix-main job pushes directly to
main, so the fix commit never triggered downstream nix.yml verification.

Mint a short-lived token via the repo's GitHub App (daimon-nous, APP_ID
+ APP_PRIVATE_KEY secrets) so the push is treated as a real event and
nix.yml fires to verify the corrected hashes.

Tested via workflow_dispatch dry-run: app token minted successfully,
checkout with app token succeeded, fix job correctly gated.

Resolves review feedback from Bugbot (r3144569551).

* ci(nix): rename lockfile check job for required status check

Rename 'check' → 'nix-lockfile-check' so the status check name is
unambiguous when added as a required check on main.

* fix(ci): harden auto-fix-main against races, loops, and silent failures

Address adversarial review findings:

1. Race condition (#1): Job-level concurrency with cancel-in-progress
   collapses back-to-back pushes; ref: main checkout always gets latest
   branch state; explicit push target (origin HEAD:main).

2. Loop prevention (#2): File-whitelist check before commit aborts if
   any file outside nix/{tui,web}.nix was modified, preventing
   accidental self-triggering.

3. Silent infra failures (#8): nix-lockfile-check now fails explicitly
   when fix-lockfiles exits without reporting stale status (catches nix
   setup failures, network errors, script bugs that bypass continue-on-error).

4. Commit traceability (#11): Auto-fix commits include source SHA and
   workflow run URL in the commit body.

5. Explicit push target (#12): git push origin HEAD:main instead of
   bare git push.

# update commit directly to main so Nix builds never stay broken.

# Safety invariants:
# 1. The fix commit only touches nix/*.nix files, which are NOT in
# the paths filter above, so this cannot re-trigger itself.
# 2. An explicit file-whitelist check before commit aborts if
# fix-lockfiles ever modifies unexpected files.
# 3. Job-level concurrency with cancel-in-progress: true ensures
# back-to-back pushes collapse to the newest; ref: main checkout
# always operates on the latest branch state.
# 4. Uses a GitHub App token (not GITHUB_TOKEN) so the fix commit
# triggers downstream nix.yml verification.
