v0.3.7 — review context fixed; the flow runs locally now

Batch release, validated end-to-end by the new local flow rig before cutting (8 real-model runs, 106¢, every stage assertion green).

#95 — review tasks state the reviewed task's caps, never their own. The reviewer's prompt now carries the proposing task's cost ceiling (baked into the review spec at mint time); legacy review tasks render no cap figures rather than wrong ones. Fixes the live mis-review where legal 80¢ subtasks were rejected against the review task's own 15¢ cap.

#96 — the local flow rig. npm run flow:local: the real runner + real claude -p against a local control plane and podman Postgres, walking propose → salvage → review mint → rejection flow-back → re-propose → review → publish with DB and prompt-content assertions at every stage, a cost meter, and a spend guard. npm run flow:smoke: its deterministic no-spend twin, now in every CI run. Retro-validated: against v0.3.5 code it reproduces the #95 incident in 5 runs / 74¢. New bugs die here now, not in releases.
