Ryan Malia 28903d8eba fix: prioritize package-lock.json in launcher to prevent Bun false positive
The bin/qmd wrapper checks for bun.lock to select the runtime, but since
bun.lock is committed to the repo, source builds using npm install are
incorrectly routed to Bun — causing native module ABI mismatches (#381)
and sqlite-vec crashes (#380).

Add package-lock.json as a higher-priority signal: if it exists, npm
installed the dependencies and Node should be used. Also fix
cleanupOrphanedVectors() to use the existing isSqliteVecAvailable()
guard instead of checking sqlite_master, which can report the virtual
table even when the vec0 module isn't loaded.

Fixes #381, fixes #380
Continuation of #362 (runtime detection false positives)
