Model, agent, and core-loop rules

• Providers: register in src/models/registry.ts#initProviders. Add the id to providerEnum and, if local, to isLocalProvider. Classify model ids through src/models/local-catalog.ts — do not hand-roll regexes in a new provider.
• Agents: register in src/agents/registry.ts. Follow the existing base-class shape in src/agents/base.ts.
• Core loop: hot paths are src/core/loop.ts, src/agents/executor.ts, src/core/mode-policy.ts, and src/core/validation.ts. Surgical edits only — never refactor these without a test covering the new behaviour.
• Mode policy: per-mode caps (tokens, turns, concurrency) live in src/core/mode-policy.ts. Changing a cap is a behaviour change — update the mode caps table in docs/ARCHITECTURE.md §4 in the same PR.
• State machine: task transitions must be in LEGAL_TRANSITIONS (src/persistence/tasks.ts). Never monkey-patch state; if a transition is missing, add it to the table with a test.
• Provider availability probes should remain ~1.5s, not long timeouts.
