Addresses all five review points from @JackChen-me on PR #70:
1. Extract shared keyword helpers into src/utils/keywords.ts so the
short-circuit selector and Scheduler.capability-match cannot drift.
Both orchestrator.ts and scheduler.ts now import the same module.
2. selectBestAgent now mirrors Scheduler.capability-match exactly,
including the asymmetric use of agent.model: agentKeywords includes
model, agentText does not. This restores parity with the documented
capability-match behaviour.
3. Remove isSimpleGoal and selectBestAgent from the public barrel
(src/index.ts). They remain exported from orchestrator.ts for unit
tests but are no longer part of the package API surface.
4. Forward the AbortSignal from runTeam(options) through the
short-circuit path. runAgent() now accepts an optional
{ abortSignal } argument; runTeam's short-circuit branch passes
the caller's signal so cancellation works for simple goals too.
5. Tighten the collaborate/coordinate complexity regexes so they only
fire on imperative directives ("collaborate with X", "coordinate
the team") and not on descriptive uses ("explain how pods
coordinate", "what is microservice collaboration").
Also fixes a pre-existing test failure in token-budget.test.ts:
"enforces orchestrator budget in runTeam" was using "Do work" as its
goal which now short-circuits, so the coordinator path the test was
exercising never ran. Switched to a multi-step goal.
Adds 60 new tests across short-circuit.test.ts and the new
keywords.test.ts covering all five fixes.
