Autoupdate fix status

Initial failures: npm ci failed (ERESOLVE), which cascaded to npm run lint/build/cov never running.

Root causes found:

1. typescript was bumped to ^7.0.2, but typedoc@0.28.20's peer dependency only allows typescript up to 6.0.x (no stable typedoc release supports TS 7 yet — only 1.0.0-dev.* prereleases exist). This broke npm ci/npm install outright.
2. firebase-tools was bumped to ^15.24.0, which regresses the Storage Emulator: bucket.deleteFiles() (used by the clean/storage jobs) fails with "Not Implemented". Verified by swapping back to 15.22.4 in isolation — failure disappears.

Changes made (compatibility pins only, no product logic touched):

• typescript: ^7.0.2 → ^6.0.3 (matches typedoc's peer range)
• firebase-tools: ^15.24.0 → ^15.22.4 (avoids the Storage Emulator regression)
• package-lock.json regenerated accordingly

All other autoupdated devDependency bumps (@types/node, eslint, prettier, typedoc patch, typescript-eslint, @eslint/js, globals) were left as-is since they installed and tested cleanly.

Verification (all commands run locally from a clean npm ci, exit codes confirmed):

• npm ci --no-audit --no-fund → exit 0
• npm run lint → exit 0
• npm run build → exit 0
• npm run cov → exit 0 (24/24 tests passing; required pointing at the pre-installed JDK 21 in my sandbox since its default java is 17 — the same JDK 21 that pr-checks.yml already provisions via actions/setup-java, so this doesn't affect CI)

Pushed commit: 85c077e4 — "fix(deps): pin typescript and firebase-tools to compatible versions"

No package version bump. pr-checks should re-run automatically on this push.
