chore: clean up Biome lint — ignore dist, suppress safe non-null assertions

Exclude dist/ from Biome scanning. Add noNonNullAssertion overrides for
files with safe Map.get()! patterns (graph.ts, refs-adapter.ts, etc).
Fix unused imports in map/index.ts and cli/commands/map.ts. Change test
edge weight from 1.414 to 1.5 to avoid noApproximativeNumericConstant.
