chore: drop expired release-notes banner; complete autohands registry (#254)

Two hygiene leftovers from the 2026-08-19 release-board census (#239).

The time-boxed ANNOUNCEMENT banner in generate_release_notes.py expired
2026-07-24, so announcement_banner() had returned "" on every call since.
Delete the mechanism rather than document it; the datetime.date import goes
with it. The banner markdown also appears as a literal fixture string in
test_slack_release_notes.py, which imports nothing from the deleted code —
kept as the file's only blockquote -> mrkdwn case, with its comment corrected.

`bin/autohands help` claimed to be "the registry of what is a CLI verb", but
eleven modules in autohands/ had grown __main__ blocks without ever appearing
in it. Nine become real verbs (generate_markdown, regenerate_navigator, the
four workspace guards, slack_release_notes, tombstone, clone_seed), each with
help text stating its actual input contract — they differ: cwd, --root, or a
positional path. The rest are declared in a new INTERNAL_MODULES array with a
one-line reason each, and printed by `autohands help`, so the registry
describes the whole package rather than a subset.

tests/test_autohands_registry.py makes that an enforced invariant: every
executable module is a verb or allowlisted, the allowlist has no ghosts, every
verb carries its SHORT_DESC + cmd_* + help_* trio, and the two lists are
disjoint. Each assertion was negative-tested to confirm it fires.
