feat: add AI agent workspace (#3062)

* chore(ai): remove local AI store now that providers live server-side

The Zustand-based useAIStore has been replaced by the server-side
aiProviders oRPC router (encrypted credentials persisted in DB).
Delete the dead store + tests, drop the ./store export, and remove
zustand/immer deps which are no longer referenced anywhere in
packages/ai/src/.

* feat(agent): archive/delete actions and read-only state for agent threads

- Backend: mark archived threads as read-only in threads.get and reject
  messages.send with CONFLICT when the thread is archived.
- Frontend: render archived threads in the sidebar with muted styling and
  an Archived badge; add a per-thread dropdown menu in the chat header
  with Archive (non-destructive) and Delete (with confirmation); show a
  read-only banner above the message list that disambiguates archived
  vs. missing-resource causes; suppress the Retry and Stop buttons in
  read-only mode.
- Tests: new packages/api/src/services/agent.test.ts covering the
  archived-thread isReadOnly flag and the archived-thread send refusal.

* fix(agent): abort run on archive and verify ownership before deleting thread

- threads.archive: before flipping status, abort any in-flight run controller
  and clear the active-run state on the thread; cleanup failures are logged
  but do not block the status update.
- threads.delete: assert thread ownership via getThread before destructive
  work so an authenticated user cannot wipe another user's attachment rows
  by passing a foreign threadId.

Adds focused tests for both behaviors.

* feat(agent): display patch diffs and surface revert conflicts

Render apply_resume_patch tool messages with a status-aware card (applied/
reverted/conflicted), expandable operation list, and a Revert button that
correctly handles RESUME_VERSION_CONFLICT responses. Adds unit tests for
the inverse-patch builder and the agentService.actions.revert flow.

* chore(agent): remove out-of-scope attachment tests accidentally added in Task 6

The Task 6 commit (73ef1acca) accidentally re-introduced three attachment-
related tests that belong to a separate task:

- `buildAttachmentModelParts > converts text, image, supported binary, and
  unsupported attachments into model parts`
- `agentService.messages.send > persists the user message with file UI parts
  and links selected attachments to it` (was failing — the `ToolLoopAgent`
  mock is not callable as a constructor)
- `agentService.messages.send > rejects attachments that are missing, foreign,
  or already linked before persisting a message`

These were likely re-added during a stash recovery and were not requested
for Task 6, whose scope was limited to the `agentService.actions.revert`
flow. Remove them along with the helpers/fixtures (`buildAttachment`,
`buildActiveThread`, `selectWhereResult`, `selectOrderByResult`) that they
were the only consumers of. `selectLimitResult` is preserved because it is
used by the revert tests.

* chore(agent): configure runtime dependencies

* feat(db): add agent workspace schema

* feat(api): add agent backend services

* feat(web): add agent workspace UI

* chore(agent): remove legacy builder assistant

* test(agent): make agent stream mocks constructible

* chore(web): remove unused resume replacement hook

* feat(api): add unsafe AI base URL flag

* chore(dev): expose local services in compose

* fix(web): normalize resume preview gaps

* feat(api): improve agent tool handling

* feat(web): polish agent workspace UI

* chore: update dependencies

* fix(api,web): address PR review feedback for agent workspace

Security/correctness:
- Restrict AI provider URLs to http/https even in unsafe mode
- Stop exposing Redis on host network by default
- Make .env.local optional and drop app profile in compose.dev.yml
- Store agent attachments with private ACL on S3
- Reset provider test status when provider/model/baseURL changes
- Decouple non-agent AI endpoints from REDIS_URL requirement
- Fix JSON Patch add inverse for existing object members
- Wrap resume patch + agent action insert in db transaction
- Validate partialMessage at runtime and rate-limit attachment uploads
- Add unique index on agent_messages (thread_id, sequence)

UX/bugs:
- Mark agent thread route as ssr: false and guard SSE chunk parsing
- Show config-specific banner only on known configuration error
- Gate AI provider checks behind loading state in resume import
- Fix relative-time formatter blank gap between 45-59 seconds
- Clarify thread delete confirmation message

Polish:
- Raise ENCRYPTION_SECRET minimum to 32 characters
- Bucket AI rate limits by resumeId/threadId/messageId
- Trim form values before submitting AI provider config
- Use single key identifier and nullish-coalesce baseURL display

* fix: address ai agent review feedback

* fix: preserve mobile agent chat state

* docs: add ai agent workspace guides

* feat: introduce design system for Reactive Resume
