feat(routing): add KiloClaw as a named routing mode (#1669)

## Summary

- Added `kiloclaw` as an explicit routing mode in both
`FRONTIER_MODE_TO_MODEL` and `BALANCED_MODE_TO_MODEL` in
`describeRouting`
- For Frontier: routes to Claude Opus with reasoning enabled and high
verbosity (same config as `plan`)
- For Balanced: routes to Kimi with reasoning enabled (same config as
`plan`)
- Updated `applyResolvedAutoModel` to pass `'kiloclaw'` directly as the
mode instead of mapping it to `'plan'`, so KiloClaw now appears in the
routing description

## Verification

- Reviewed the diff manually; the change is additive and consistent with
existing mode configurations
- Typecheck could not be run due to missing `tsgo` binary in the
environment

## Visual Changes

N/A

## Reviewer Notes

Previously, `featureHeader === 'kiloclaw'` was mapped to `'plan'` before
lookup, so KiloClaw was silently sharing `plan`'s routing without
appearing in `describeRouting`. Now it has its own named entry, making
the routing description accurate and allowing independent tuning in
future.
