Render the app's SwiftUI surfaces to PNG headlessly so an agent can SEE the UI
and validate it against the specs, locally — no menu bar, no mic, no
screen-capture, deterministic.
- SnapshotRenderer + main() gate: `OQ_SNAPSHOT_DIR=<dir> openquack` renders the
recording overlay's states (listening / thinking / pasted / interrupted /
kickoff) to <dir>/*.png via ImageRenderer, then exits.
- The render→see→validate→fix→re-render loop, run on the first output, caught two
interrupted-overlay bugs that no unit test would: the notice was truncated
("…audio devic…") and the headline misread "Copied to clipboard" on a recording
that was cut short. Fixed here — headline → "Recording interrupted", notice →
"Saved what we captured" (fits the pill) — confirmed by re-rendering.
Build + 269 tests green.

SPEC
SPEC-044 (Agent-driven UI snapshot validation)
Milestone
Adoption focus — auto-validation / ship confidently.
Why
Lets an agent see the UI and validate it against the specs locally (no cloud, no mic, no screen-capture) — catching the bug class unit tests miss: correct logic, wrong rendered UI. Directly from "the agent should drive testing, see the UI to validate by the specs, and improve on its own, run locally."
