ci: run the node:sqlite job against the full tree, not a pruned one

The job as first written installed with --omit=optional, reasoning that a player has
no native module. It failed immediately with sixty "Cannot find module
'better-sqlite3'" errors — because the TESTS require it directly, as a harness to
inspect the database they are making assertions about. Pruning it tested nothing but
the test files.

Installing everything and forcing ST_SQLITE_DRIVER=node is also the stronger check:
the server under test runs on node:sqlite while the harness reads the same database
files with the native driver, so a divergence between the two surfaces as a failing
assertion rather than as one driver agreeing with itself.

This is the configuration that was actually verified locally — 1762 pass / 0 fail on
both drivers. The pruned variant was written afterwards and never run before pushing.
