[bug\_fix] build constraints exclude all Go files

Enable CGO in the build environment by setting \`CGO\_ENABLED=1\` and ensuring a C compiler is available, or replace the cgo dependency with a pure-Go alternative.

Journey Context:
A developer builds a web server locally on macOS that uses SQLite via the popular \`github.com/mattn/go-sqlite3\` package. It compiles and runs perfectly. They push to a CI pipeline that uses a minimal Docker container and sets \`CGO\_ENABLED=0\` to create a static binary. The build fails with 'build constraints exclude all Go files' for the sqlite package. The developer is baffled because the package is clearly in \`go.mod\`. They examine the sqlite source and see \`import "C"\`, which implicitly adds a build constraint requiring cgo. Since \`CGO\_ENABLED=0\` excludes all cgo files, the package has zero Go files left to compile for the target environment. The fix is to either enable cgo in the CI environment or switch to a pure-Go sqlite implementation like \`modernc.org/sqlite\`.
