refactor(cli): replace better-sqlite3 with sql.js (pure WASM)

- Remove native C++ addon dependency, no more pnpm approve-builds
- sql.js loads SQLite as WASM, zero compilation required
- WASM init is singleton (once per process)
- Add queryAsObjects() adapter for sql.js columnar → row format
- Tests migrated to sql.js (16 passing)

Implements RFC #63

pnpm-lock.yaml
