Inspired by openai/codex#26966 (closed not planned). codex_goal.py is a
standalone CLI that stores one versioned, project-keyed goal per repo
outside Codex's own sandbox, and injects it as plain user context on
every new or resumed `codex exec` run. Writes are atomic and locked,
runs never mutate the goal, Codex is spawned via argv (no shell), and
signals are forwarded for normal cancellation behavior. 16 unit tests
plus a recorded two-run + crash-recovery demo, verified on macOS and
in the project's Colima Linux container. Launch page at
ventures/codex-goal/site/index.html uses a self-contained
scoreboard/arcade identity (vendored OFL DSEG7 font, no external
requests) distinct from the other ventures.
