Subject: [PATCH] fix(cli): improve better-sqlite3 postinstall rebuild for
 cross-platform installs (#312)

Replace unreliable process.dlopen() platform detection with explicit
platform/arch comparison against the build target (linux-x64). On macOS,
dlopen can load an incompatible binary without throwing, causing the
postinstall script to skip the rebuild entirely.

- Detect platform mismatch via process.platform/arch instead of dlopen
- Fail the install (exit 1) if rebuild fails, instead of warning silently
- Verify rebuilt binary loads correctly after rebuild
- Add pre-flight binary check in CLI entry point as a safety net
