Wires the --nice <n> flag (and GBRAIN_NICE env) through the CLI (issue #1815):
- jobs work: applies niceness + registers the worker; cleanup on finally and
  process.on('exit').
- jobs supervisor: applies in the foreground-start path only (after the
  --detach fork), passes the apply result into MinionSupervisor.
- supervisor.ts: nice opts, extracted testable buildWorkerArgs (appends
  --nice), emits niceness on started/worker_spawned audit events.
- jobs stats / supervisor status: surface effective worker + supervisor nice.
- doctor: separate supervisor_niceness check (warns on requested != effective)
  so it can't clobber the supervisor crash-check precedence; registered in
  doctor-categories.

Unit tests for issue #1815: parseNiceValue rejects 3.5/10abc that parseInt
would accept; applyNiceness re-reads effective on EPERM; registry ESRCH/EPERM +
pid-reuse guard + brain-isolated path; readSupervisorPid states; parseNiceFlag
flag>env precedence; buildWorkerArgs --nice propagation.

- minions-deployment.md: niceness tuning section (full concurrency, low priority).
- KEY_FILES.md: entries for niceness.ts, worker-registry.ts, supervisor-pid.ts;
  supervisor.ts entry notes buildWorkerArgs + nice opts.

The enrich_thin cycle phase (src/core/cycle.ts ALL_PHASES, between
conversation_facts_backfill and skillopt) shipped without updating the
e2e phase-order expectation, so dream-cycle-phase-order-pglite failed on
master. Sync the expected list to the real ALL_PHASES order.

…ll contract

v0.41.13.0 intentionally dropped the "--break-lock + --all is refused" guard so
cron can self-heal every source in one call (sync.ts runBreakLock iterates
sources under --all). The e2e test still asserted the old exit-1 refusal and
failed on master. Assert the current contract: the combination is accepted and
takes the iterate / no-active-sources path (exit 0, no refusal message).

The native fsevents watcher occasionally missed a freshly written file, timing
out the 15s waitFor (~1/3 on master under load). Three fixes:
- inject a polling chokidar watcher via the source's _watchFactory seam
  (usePolling, 20ms interval) so detection never depends on fsevents timing;
- drop deterministic fixtures BEFORE start so the initial scan
  (ignoreInitial:false) emits them, keeping live-watch coverage only where it's
  robust;
- poll for the dedup hit instead of a fixed 600ms sleep.
15/15 green under stress.

connect-bearer and serve-stdio-roundtrip init a PGLite brain and spawn serve,
but passed {...process.env} through — leaking an ambient DATABASE_URL /
GBRAIN_DATABASE_URL into the subprocess, which then came up on Postgres and
failed the `engine: pglite` assertion. Strip both DB vars from the spawned env
so the tests are deterministic whether or not the shell/CI has a DB URL set.

The DATABASE_URL/GBRAIN_DATABASE_URL strip used `delete` on a narrowly-typed
env literal (tsc-only failure; bun test doesn't typecheck). Annotate
connect-bearer's env as Record<string,string|undefined> and build serve-stdio's
as a concrete Record<string,string> (StdioClientTransport.env rejects undefined).
Runtime behavior unchanged (7/7 + 3/3 green).

worker-registry.test.ts sets process.env.GBRAIN_HOME per-test so gbrainPath
resolves to a temp dir, then lazy-imports the module — a process-global
mutation the parallel isolation lint (rule R1) forbids. Rename to
worker-registry.serial.test.ts: it runs in the serial pass (own bun process,
max-concurrency=1) where env mutation is safe, and the lint skips *.serial
files. No logic change (6/6 green); fixes the failing `verify` CI job.
