chore(ui): remove dead forge exports and unused useForgeProvider hook

- Remove useForgeProvider React hook (dead; only imperative
  getForgeProviderForDirectory was used, by tests)
- Remove toLookupOptions export from useForgeLookup (only used
  within file)
- Remove ForgeEditForm barrel re-export from forge/actions/index
  (imported directly by ForgeEntityActions)
- Strip forge/index.ts barrel to only actually-consumed exports
  (buildForgeProvider, ForgeIssue, ForgeCommit, ForgeFileChange,
  mapGithubPr)
- Remove ForgeTimelineSection/ForgeChecksSection from views barrel
  (imported directly by ForgeEntityDetailView)
