fix(commands): close the promises the command templates could not keep

DEL B chunk `interview` (+ discover/status/cleanup/help). Fasit written before
the run predicted 8 defects and refuted 4 candidates; all 8 confirmed, all 4
refutations held, and three predictions turned out too narrow.

- M-BUG-36: `drift --list` reached the command as 0 bytes. drift-cli accepted
  --output-file but list mode ignored it, and the listing goes to stderr, which
  the command discards per ux-rules rule 2. Fixing the caller alone would not
  have helped.
- M-BUG-37: feature-gap's "Create backup" step ran fix-cli without --apply.
  Dry-run is the default, so no backup existed (backupId: null) while the
  command went on to edit config believing it could roll back.
- M-BUG-38: fix-cli told users to recover with scanners/rollback-cli.mjs, which
  does not exist. Dead reference in the one message read after a bad fix.
- M-BUG-21 fourth arm: five templates carried literal [--global]/[--full-machine]
  inside executable bash blocks. A bracketed placeholder does not start with a
  dash, so every scanner's arg loop takes it as the scan target.
- interview and analyze never said which session they act on; interview could
  rewind a finished session; cleanup interpolated an unvalidated id into rm -rf
  (an empty id deletes every session); status advertised a `resume` command that
  does not exist and documented an `all` argument it never parsed.

TDD: 9 red tests first, including a machine sweep for dead /config-audit
references and for bracketed flags in bash blocks. Suite 1432 -> 1441/0.
Frozen v5.0.0 snapshots untouched; --raw/--json contracts unchanged.
