v0.4.12

The Build Loop, and multi-agent runs that keep going instead of timing out.

The Build Loop. A new opt-in workflow runs a task through plan → implement → verify → review → merge, with the verifier checking the worker's actual edits in an isolated worktree and a merge gate that only lands changes when verification is green and review is clean:
```
/build add rate limiting to the API
```
It can escalate on its own. A multi-step request can enter the loop automatically; tune it with cli.buildLoop (off / escalate / always, default escalate).
Runs reconnect instead of timing out. Model calls and the memory connection now reconnect with backoff (honoring Retry-After) rather than failing at a hard deadline, so slow models, large reviews, and brief network blips no longer kill a run.
The session keeps going after spawning agents. When a turn ends with background agents still working, BrainRouter waits for them and continues automatically — no more manual /continue.
Type while it's busy. Messages entered mid-turn are queued and run one at a time after the current turn finishes:
```
/queue
/queue remove 2
/queue clear
```

Child and worker timeouts wait instead of killing. A timeout now only bounds how long the parent waits; the child runs to completion. Use timeoutMs: 0 to wait until done.
Fan-out builds. A build split into multiple slices runs each in its own held worktree and merges them with overlap detection; review-gate ad-hoc workers with cli.worktreeMergeReview.
Optional loop-until-green self-repair. When cli.buildLoopMaxRepairs is greater than 0, a failed build retries implement → verify → review until it passes (default off).
Active phase, surfaced. /ps, /agents, and an optional statusline segment now show the running phase (e.g. Implement (2/4)).
Search actually searches. grep_search now does real regular-expression matching and accepts a single file or a directory.
Accurate costs. /tokens now includes tokens spent by child and sub-agents.

Worktree garbage collection no longer removes a running child's worktree.
Worker-thread state moved under your BrainRouter home directory.
Workflow agents with custom role names map to the closest built-in role instead of failing.
