a460b856c2 perf(db): drop redundant idx_edges_source / idx_edges_target (#142 )

Both narrow indexes are fully covered by the existing (source, kind)
and (target, kind) composites via SQLite's left-prefix scan, so
they're dead weight on every write. Empirical measurements (from the
spike script in PR #122 on a 50K-node / 250K-edge synthetic DB):

  - DB size: 34.7 MB → 27.0 MB (-22.2%)
  - Bulk insert (250K edges): 590ms → 431ms (1.37× faster)
  - source/target lookup latency: no regression

Adds migration v4 to drop both on existing databases; fresh-DB schema
no longer creates them.
