feat(workspaces): sign the workspace login handoff and gate readiness (#11671)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Managed worktree services run isolated Paperclip instances with
cloned databases.
> - A reachable service was reported as ready even when its database,
runtime identity, or login path was not usable.
> - The first candidate added verified database seeding and managed
repair in #11665.
> - This pull request consolidates that candidate with signed login
handoff and a complete readiness contract.
> - Post-QA fixes close five defects in repair identity, repair
responses, UI retry, seed journal handling, and seed-source trust.
> - The benefit is a workspace that either opens safely or reports one
accurate recovery action.

## Linked Issues or Issue Description

No public GitHub issue exists for this work, so the problem is described
here.

**What happened**

Managed workspace URLs could return HTTP 200 and report ready while
login failed. QA also found cases where repair used the wrong instance
identity, returned a generic error, left the UI stuck, rejected a safe
journal lag, or trusted a mutable workspace manifest.

**Expected behavior**

Opening a ready workspace signs the board user in to the correct
isolated instance. Provisioning and repair use a registered source and
report a structured recovery state.

**Actual behavior**

Entry depended on a password copied into the clone. Several failure
paths could publish stale readiness, hide the repair precondition, or
trust state that the workspace could modify.

**Additional context**

This pull request includes the commits first published in #11665. That
pull request keeps the original base head for review history. This
consolidated pull request is the merge candidate. Related open readiness
work includes #11575 and #11621.

## What Changed

- Adds a short-lived, signed, single-use login ticket. It binds the
user, workspace, instance, and runtime origin.
- Exchanges the ticket through Better Auth. It creates the session and
cookie through the supported adapter path.
- Adds protected workspace readiness fields for the database, clone
data, login handoff, seed phase, and runtime identity.
- Fails readiness closed when the guest has no company or
execution-workspace binding.
- Binds ticket issuance to the exact cloned user and active company
membership selected for the handoff.
- Verifies every current active board identity through the exact-user
handoff before publication or reuse.
- Gates managed runtime publication on the readiness contract and the
recorded worktree instance identity.
- Refreshes runtime work products from the live runtime row after a port
change.
- Adds one workspace access card with ready, degraded, repairing, and
failed states.
- Uses the runtime response identity for repair. It returns structured
repair precondition errors.
- Lets a valid source journal lag converge during provisioning.
- Binds seed and repair manifests to a source registered outside the
agent-writable worktree.
- Clears recovered UI errors so a successful retry can open the
workspace.
- Makes runtime tests register canonical sources and avoid ports owned
by live host listeners.
- Keeps Vitest on source suites when compiled `dist` trees exist.
- Isolates CLI and adapter tests from ambient AWS and runtime API
environment variables.
- Preserves a 404 response for cross-company workspace ID lookups before
runtime authorization.
- Makes concurrent single-flight coverage independent of
path-canonicalization scheduling order.

## Verification

The following checks passed on the integrated head:

```sh
pnpm -r typecheck
pnpm build
pnpm check:token-gates
pnpm --filter @paperclipai/db check:migrations
```

- The server source lane passed 420 files and 4,953 tests. Five tests
were skipped.
- The CLI lane passed 57 files and 385 tests.
- The database lane passed 26 files and 97 tests.
- The shared package passed 58 files and 506 tests.
- The adapter utility lane passed 640 tests. Four tests were skipped.
- The Claude adapter passed 220 tests. One test was skipped.
- The Codex adapter passed 323 tests.
- The OpenClaw adapter passed 13 tests.
- The OpenCode adapter passed 42 tests.
- The plugin SDK passed 45 tests.
- The workspace runtime suite passed 124 tests.
- The caller-scoped readiness and handoff suite passed 52 tests.
- The workspace provisioning shell suite passed 7 tests.
- The runtime exposure suite passed 17 tests while live host mappings
occupied fixed test ports.
- `git diff --check` passed and the worktree is clean.

The serialized route lane will run in GitHub CI with its normal shards.
No deployment or active-workspace migration was performed.

## Risks

- This is a medium-risk authentication and runtime-readiness change.
- The login ticket uses exact origin, workspace, instance, and user
binding. It has a short expiry and a one-time nonce.
- Runtime publication is stricter. A real readiness, identity, per-user
handoff, or control-plane database disagreement now blocks publication.
- This pull request supersedes #11665 as the merge candidate. Close
#11665 after this pull request merges.
- No new database migration is included. The lockfile and workflow files
are unchanged.
- Deployment and active-workspace migration are intentionally outside
this pull request.

## Model Used

Claude Opus 5 (`claude-opus-5[1m]`), 1M context, extended thinking, tool
use, and code execution produced the main candidate. OpenAI GPT-5
(`gpt-5`) through Codex, with agentic reasoning, tool use, and code
execution, integrated the post-QA fixes and hardened the test gates. The
Codex context-window size was not exposed.
