refactor(cli): decouple daemon native deps from CLI global install

- Move @uncaged/nerve-daemon from runtime to devDependencies
- Dynamic import daemon from workspace node_modules at runtime
- Add daemon-bootstrap.ts as separate entry for background daemon spawn
- Extract run-foreground-kernel.ts and workspace-daemon.ts modules
- Add daemon-types.ts for structural types (no runtime daemon import)
- Rebuild better-sqlite3 in workspace during nerve init
- Validate daemon process liveness after spawn in background mode
- Mark @uncaged/nerve-daemon as external in tsup config

Closes #41
