merge: resolve v1.22.2 conflicts with custom

Per Q4 resolution (documented on kanban t_83741c53):
- .github/workflows/*: KEEP custom deletion (fork uses Gitea Actions under .gitea/workflows)
- ChatInput.tsx: KEEP custom forge picker states + provider-aware linkedPr
- WorkStatusContextSection.tsx: combine imports (WorkStatusPill + useConfigStore)
- WorkStatusPrimaryGroup.tsx: upstream nested-git/bootstrap-gate base + custom GitLab/Gitea forge rows
- NewWorktreeDialog.tsx: combine dialogs; keep custom MR/PR branch resolution
- SettingsView.tsx: custom deps minus undefined openThirdPartyProviderSetup
- search.ts + search.test.ts: KEEP upstream (enter-to-send, large-text-paste, first-party integrations)
- tr.ts: drop 4 auto-merge duplicate gitView.empty.* keys
