fix(tui): include thinking effort in status line payload

[GarryCodespace]

Related Issue

Resolve #2713

Problem

Custom status line commands receive a JSON snapshot on stdin, but that snapshot omitted the current thinking effort. The built-in footer therefore updated when the effort changed while a custom footer had no equivalent source of truth.

What changed

• Add thinkingEffort to the custom status line payload and populate it from the current TUI state.
• Add regression coverage for the footer-to-command payload path.
• Document the field in the English and Chinese configuration references and add a patch changeset.

Verification

• pnpm exec vitest run apps/kimi-code/test/tui/components/chrome/footer-status-line.test.ts — 17 passed
• pnpm --filter @moonshot-ai/kimi-code typecheck
• Focused type-aware oxlint — no new errors
• pnpm --filter kimi-code-docs build
• CLI package suite — 2,662 passed; one unrelated timing-sensitive test failed in the full concurrent run and passed when rerun alone
