feat: integrate fork work onto upstream main (squashed)

Squash-merge of feat/autofix-pr-test (69 commits) onto upstream/main
with -X ours strategy (upstream as authoritative for content conflicts).

Key features brought in from fork:
- LocalMemoryRecall + VaultHttpFetch tools (end-to-end wired)
- /local-memory, /local-vault, /memory-stores, /skill-store interactive panels
- /agents-platform, /schedule, /vault command scaffolding
- /login: switch / replace / remove of workspace API key
- statusline refactor (built-in status row, /statusline as info command)
- autofix-pr command + workflow

Conflict resolutions (upstream-wins):
- 10 .js command stubs kept from upstream (alongside fork's .ts implementations)
- src/components/BuiltinStatusLine.tsx accepted upstream's deletion
  (fork's wire-up references in StatusLine.tsx will be cleaned up next)
