Add a read-only `warden route` command group (list/show/find) that reads
registry/routing/catalog.yaml and tells a worker which subsystem owns a need
and which wiki/canon doc to follow. ops-warden still executes exactly one lane
(SSH); routed entries return a pointer and never call any subsystem.
- src/warden/routing/: models.py + catalog.py loader; enforces the
no-double-source rule (non-SSH entries with steps/cert_command fail validation),
dup-id and schema checks.
- route list (active-only unless --all, --tag), route show (SSH appends steps +
cert pattern; routed ends with "next action on <owner> — see <wiki_ref>"),
route find (keyword ranking, --json).
- tests/test_routing.py: load/validation, find ranking, CLI JSON shapes, plus a
drift guard (every wiki_ref anchor resolves; every entry has a reviewed date).
- Docs: wiki/AccessRouting.md CLI section, README quick reference, SCOPE A3 -> A4.
