chore(release): v1.2.0

[crisng95]

Release commit for v1.2.0 — the first since v1.1.0 (2026-05-09).

What's in it

One line of substance plus one bug fix:

• agent/main.py — FastAPI(version=…) 1.1.0 → 1.2.0. This is the canonical version; 939b956 established that a release touches exactly this line.
• README.md — the changelog's ### Unreleased heading becomes ### v1.2.0 — 2026-09-18.

The drift this also fixes

ccf89c6 put "0.2.0" in two places in agent/main.py. The v1.1.0 release bumped only the FastAPI(...) line, so /health has been answering 0.2.0 ever since while the app reported 1.1.0 — three releases stale, on the endpoint CLAUDE.md tells you to curl before doing anything else:

curl -s http://127.0.0.1:8100/health

Releasing again would have widened the gap to four. /health now reads app.version instead of restating it, so there is one string to bump rather than two literals that agree only by luck.

What is deliberately not bumped

extension/manifest.json stays at 0.3.2. It tracks the extension's own lifecycle, and a bump there forces a user-visible reload in chrome://extensions. dashboard/package.json stays at 0.0.0 — never released.

Verification

• pytest tests/unit → 272 passed (with ffmpeg-full ahead on PATH; a stock Homebrew ffmpeg lacks drawtext and fails 13 unrelated tests)
• /health and app.version both return 1.2.0, checked by calling the handler rather than reading the source — TestClient cannot be used here, the lifespan installs signal handlers and only runs on the main thread

Not verified

The Omni envelopes from #48. They are live-verified per that PR and the tests lock their shape, but nothing has submitted through a signed-in Flow tab since the merge resolution in #50. Worth one real Omni first-frame generation before cutting the tag if you want the release to stand on more than unit tests.

After merge

No CI exists, so the tag is the record rather than a trigger, and nothing publishes:

git checkout main && git pull
git tag -a v1.2.0 -m "v1.2.0"
git push origin v1.2.0
gh release create v1.2.0 --title "v1.2.0" --notes-from-tag
