fix(ci): WASM WIT compat sqlite3 duplicate symbol conflict (#953)

* fix(ci): use explicit features in WASM WIT compat test to avoid sqlite3 symbol conflicts

The `import` feature (added in #903) brings in `rusqlite[bundled]` which
conflicts with `libsql-ffi` — both bundle SQLite C code, causing duplicate
symbol linker errors. Use explicit features matching the test matrix instead
of `--all-features`.

* fix: replace rusqlite with libsql in import module to fix sqlite3 symbol conflict

The `import` feature used `rusqlite[bundled]` which bundled its own SQLite
C code, conflicting with `libsql-ffi` (also bundles SQLite). This caused
duplicate `sqlite3_*` symbol linker errors when both features were enabled
via `--all-features`.

Replace `rusqlite` with `libsql` (already a dependency) in the import
reader. The `import` feature now implies `libsql`. This eliminates the
duplicate symbol conflict and allows `--all-features` to compile cleanly.

Also restores `--all-features` in the WASM WIT compat CI test (now safe)
and converts all import test helpers from rusqlite to libsql.
