feat(sf): port sf-home, memory-embeddings, component-types, workflow-install + sweep

- sf-home.ts: new — resolves ~/.sf/ path and SF home dir helpers (port of gsd-home.ts)
- memory-embeddings.ts: new — embedding helpers for memory similarity search
- component-types.ts: new — Component, ComponentManifest, ComponentHook type defs
- workflow-install.ts: new — workflow installation from local/remote sources
- auto-post-unit.ts: clearEvidenceFromDisk after successful verification
- routing-history.ts: add cost-per-token tracking to routing decisions
- workflow-{manifest,templates}.ts: hardening sweep
