fix(parser): support new .kimi-code session layout and add .kimi_openclaw to OpenClaw defaults

[liaocaoxuezhe]

Kimi Code now stores sessions under .kimi-code/sessions/<workdir>_<hash>/session_<uuid>/agents/<agent>/wire.jsonl. Update DiscoverKimiSessions, FindKimiSourceFile, and ParseKimiSession to handle this layout while keeping compatibility with the legacy .kimi/sessions structure.

Also include .kimi_openclaw/agents in AgentOpenClaw default directories so sessions from the Kimi-packaged OpenClaw distribution are synced.

roborev: Combined Review (154b35e)

Medium:

• internal/sync/engine.go:698, internal/sync/engine.go:5978 - The new .kimi-code layout is only added to parser discovery; incremental sync paths still assume <project>/<session>/wire.jsonl. A changed .kimi-code/.../session.../agents/<agent>/wire.jsonl file is ignored by SyncPaths/watcher sync, and SyncSingleSession derives the project as agents for this layout. Extend the Kimi path classifier and single-session project derivation to handle the five-component .kimi-code relative path, using the workdir directory as the project, and add sync-engine tests for SyncPaths and SyncSingleSession.
