chore(release): bump version to 2.7.1

Ships the fixes that landed on main after the 2.7.0 cut:

- #139 (f3ea1a3): understand-knowledge — Windows path separators in
  wikilink resolution + omit empty `category` so KnowledgeMetaSchema's
  `z.string().optional()` no longer drops every article node. Closes #151.
- #147 (fafb888): understand-domain — resolve $PLUGIN_ROOT at runtime
  for symlink installs.
- f71bad5: understand — persist canonical edge direction during merge,
  fixing the 153k auto-correction cascade. Closes #140.
