feat(wiki): sync upstream v2026.10.4 core maintenance

Selectively port source hashing, locked manifest/memory writes, path-aware
link lint and graph analysis, and revision-checked staging from upstream
4f457e154653756b04802d5aeb25c20f42b4770c. Record source hashes and exclusions.

Preserve local archive/catalog citations, curated manifest metadata, config
location, file-index and MCP behavior. Wire maintenance guidance into four
skills without migrating vault contents or changing running services.

Validation: 609 tests passed, including existing MCP/file-asset regressions
and imported upstream maintenance tests. Read-only vault status left shared
metadata hashes unchanged. Wiki MCP remains inactive; orders MCP is active.
