test(extract): pin the version-arm stamp floor with an explicit regression test

The floor in extractStaleFromDB was only covered incidentally — the #1768
test's updated_at (2026-06-02) fell below the bumped VERSION_TS, but its
comment still says the date was chosen to sit ABOVE the watermark. A future
date 'repair' there would silently drop floor coverage. This test pins it
directly: pre-watermark page clears after --stale and stays cleared.
Verified fail-without-fix against master's extract.ts.

- * #1525 — positional subcommand translation.
- *
- * Pre-fix, `gbrain autopilot status` silently fell through to "start daemon"
- * because `runAutopilot()` only branched on flag forms (`--status`, etc.).
- * `status` was treated as a stray positional and ignored.
- *
- * This translator maps known positional subcommands to their flag form so
- * `autopilot status` is equivalent to `autopilot --status`, then rejects
- * any unrecognized positional with a fail-loud error before any side
- * effect (lockfile, daemon spawn, sync dispatch) runs.
- *
- * Scope decisions:
- *   - Known aliases: `status` → `--status`, `install` → `--install`,
- *     `uninstall` → `--uninstall`, `start` → (drop; default daemon launch).
- *   - `stop` is intentionally NOT aliased here. Stopping a running daemon
- *     is a new behavior (read PID from lock, SIGTERM, drain) that deserves
- *     its own design and PR. Users typing `gbrain autopilot stop` today get
- *     the unknown-positional error with the canonical alternatives.
- *   - At most one positional allowed; multiple positionals fail loud.
