feat(bots): add rhodibot per-repo directive — full enforcement (software/language repo)

Every other estate repo carries .machine_readable/bot_directives/rhodibot.a2ml; these
three lacked it, so rhodibot (the deterministic RSR verifier) had no per-repo allow/
deny/scope guidance here. Adds it modelled on the estate schema (schema_version 1.0),
with the deterministic licence guards in deny: never relicense third-party/vendored,
never change an undeterminable licence (leave untouched), never convert deliberate
(non-drift) licences. SPDX normalisation to the declared licences (code -> MPL-2.0,
prose -> CC-BY-SA-4.0) is allowed (rhodibot is symbolic/deterministic, out of scope
of the neural-agent no-automated-licence-edits rule). root-shape: ok.
