docs(models): delegate Kimi example default

Remove the release-specific model from the Kimi launcher example so an unoverridden session uses the default already configured in the Kimi CLI.

Document the ownership boundary, assert that the spawn environment omits HARNESS_KIMI_MODEL when no model is declared, and ratchet the retired lint allowance.

Tests: 12 Kimi spawn-environment tests; structural example load; staged pre-commit including YAML and hardcoded-model checks.

+This contract is intentionally pure and side-effect free. Runtime callers adapt
+provider discovery into candidates at the boundary; later migrations can move
+smart routing and remaining policy decisions without coupling them to catalog I/O.
+
+## Runtime Default Migration
+
+The first runtime slice adapts the MLflow provider catalog into normalized
+resolver candidates and moves unresolved executor/native defaults behind that
+boundary:
+
+- Explicit request, spec, ucode, and provider-configured models still win and do
+  not depend on discovery.
+- Generic Anthropic/OpenAI providers and Databricks gateway paths resolve the
+  appropriate Claude/OpenAI catalog family with the `default` intent.
+- Catalog capability, context-window, and pricing data become normalized
+  metadata; missing capability facts remain unknown rather than supported.
+- A missing live catalog produces a clear configuration/discovery error instead
+  of silently selecting a stale release-specific fallback.
+- Executor and native-launch tests stub the catalog boundary, while catalog and
+  resolver tests exercise metadata normalization and selection independently.
+
+Static picker rows, smart-routing tiers, context/wire heuristics, and CI model
+inputs remain separate migration slices because they require different discovery
+or configuration sources.
+
+## Smart Routing Migration
+
+Smart routing now treats the runner's live worker catalog as its only candidate
+source. Provider-relative cost metadata orders candidates for the stable `fast`,
+`balanced`, and `powerful` intents; catalog order remains the tie-breaker when
+cost is unknown. If discovery is unavailable, routing skips the override and the
+harness keeps the provider-resolved default instead of consulting a stale table.
+
+The remaining exact compatibility exclusions in smart routing are temporary
+wire-API workarounds. They stay isolated until catalog wire metadata can express
+the affected harness constraints without model-name checks.
+
+## Kiro Picker Migration
+
+The Kiro Web picker now runs `kiro-cli chat --list-models --format json` on the
+bound runner and forwards the CLI's model ids, default, descriptions, context
+windows, and credit rates. The server caches the runner response through the
+same asynchronous picker path as Codex, so provider changes no longer require an
+Omnigent source update and snapshots do not block on the CLI process.
+
+## Ad-hoc CLI Defaults
+
+Minimal agent YAMLs that declare neither a harness nor a model now resolve the
+Databricks OpenAI-family default from the provider catalog during bundle
+materialization. `--model` and `OMNIGENT_MODEL` remain higher-precedence explicit
+choices. If discovery is unavailable, the CLI asks for one of those explicit
+values instead of silently baking a release-specific model into the bundle.
+
+## Onboarding Defaults
+
+Provider setup derives its suggested default from the live catalog after
+excluding specialty modalities. Stable family preferences choose broadly
+accessible Anthropic and OpenRouter tiers without naming a release. When the
+catalog is unavailable, onboarding accepts an explicit value instead of
+prefilling a source-controlled model pin.
+
+## Kimi Example Default
+
+The Kimi launcher example declares only the harness. With no explicit
+`--model` or session override, Omnigent omits `HARNESS_KIMI_MODEL` and lets the
+Kimi CLI use the default from its own provider configuration.
