Lifts resilience.ts from the daemon into core. Landing page (web/src/
landing.ts:938, :1028) promised circuit-breaker + cost-tracking to every
consumer; this wires the implementation behind the promise.
- `CircuitRegistry`, `AegisCostTracker` classes (wrap llm-providers' managers)
- `withRetry` (exponential backoff + jitter, retryable error detection)
- `withFallback` (primary → fallback with optional predicate)
- `resilient(service, op, { circuits, fallback?, retry?, circuit? })` combinator
- `markProviderExhausted` / `isProviderExhausted` (delegates to llm-providers'
defaultExhaustionRegistry — one global exhaustion state per process)
- `createResilience({ budgets, onEmergencyBudget? })` factory that returns
`{ circuits, costs, ledger }` with the ledger event listener wired inside
Monthly budgets. Those are operator-specific (daemon's $20 Anthropic / $5
Groq / $10 Cerebras ≠ anyone else's). Core exposes the factory; consumers
supply their numbers. This also keeps core's module load side-effect-free:
the ledger event listener only fires for consumers that call the factory.
This pulls @stackbilt/llm-providers in as a core dep (file: link) — which
is a first slice of #24 (Phase D adoption). Not touching cognition.ts,
groq.ts, or claude.ts call sites in this PR; those remain for #24 proper.
- core typecheck: clean
- core tests: 1474 passed, 1 skipped
- daemon typecheck against this branch: clean (PR filed separately)
- daemon tests against this branch: 1692 passed, 7 skipped

Core now depends on @stackbilt/llm-providers via file: link (#33). Update CI to checkout llm-providers alongside aegis-oss and build it before running npm ci in web/, matching the pattern daemon's CI uses. - Nest aegis-oss checkout under aegis-oss/ so sibling repos resolve the file:../../llm-providers path. - Build llm-providers (publishes from dist/) before core install so the file: symlink resolves types.

Summary
Lifts `kernel/resilience.ts` from the daemon into core. Landing page (`web/src/landing.ts:938`, `:1028`) promised circuit-breaker + cost-tracking to every consumer; this wires the implementation behind the promise. Closes #33.
What's in core now
What does NOT live in core
Monthly budgets. Those are operator-specific — daemon's `$20` Anthropic / `$5` Groq / `$10` Cerebras ≠ anyone else's. Core exposes the factory; consumers supply their numbers. This also keeps core's module load side-effect-free: the ledger event listener only fires for consumers that call the factory.
Scope note (partial #24)
This pulls `@stackbilt/llm-providers` in as a core dep (`file:` link) — which is a first slice of #24 (Phase D adoption). Not touching `cognition.ts`, `groq.ts`, or `claude.ts` call sites in this PR; those remain for #24 proper.
