Fix(config): remove stale apps/ references from workspace configs

Cleans up leftover configuration from the apps/ → docs/ restructuring
(see ADR-0001 update). Neither file had any effect anymore since the
apps/ directory no longer exists, but both left stale references that
could confuse future contributors.

- pnpm-workspace.yaml: removed the unused "apps/*" package glob
- .changeset/config.json: removed the "ignore": ["apps/docs"] entry,
  since docs/ is not tracked as a pnpm workspace package and the
  entry had no effect
