docs(WP-0010): sharpen mission to "issue SSH, route the rest" + pointer catalog

Implements WARDEN-WP-0010 (charter + pointer catalog). ops-warden issues
short-lived SSH certificates and routes every other credential need to the
subsystem that owns it — no desk metaphor, one execution lane.

- wiki/AccessRouting.md: role/boundary, issue-vs-route matrix, anti-patterns
- registry/routing/catalog.yaml: machine-readable pointer layer (6 active + 1
  draft). No-double-source rule enforced structurally — authored steps/cert_command
  only on the warden_executes:true SSH entry; every wiki_ref anchor resolves
- wiki/CredentialRouting.md: catalog-keyed index + no-duplicate-interfaces note
- INTENT/SCOPE/AGENTS/repo-boundary/capability: aligned to the new framing;
  SCOPE notes A3 -> A4 lands with WP-0011 warden route CLI
- WP-0011/0012 + WP-0010: state_hub id writeback; WP-0010 marked done
