refactor(sqlite): Replace modernc.org/sqlite with ncruces/go-sqlite3

Replace the modernc.org/sqlite driver with ncruces/go-sqlite3 driver
throughout the codebase. This provides a consistent SQLite implementation
using a single library (ncruces/go-sqlite3) which is pure Go and uses
WebAssembly, requiring no CGO.

Changes:
- Replace modernc.org/sqlite imports with ncruces/go-sqlite3/driver
- Rename vet_modernc.go to vet_sqlite.go
- Rename sqlite_modernc.go to sqlite.go
- Remove modernc.org/sqlite and its dependencies from go.mod
- Make github.com/ncruces/go-sqlite3 a direct dependency
