Turbopack emits invalid VLQ column deltas in source maps for already-minified vendor sources (Firefox rejects with `has invalid "mappings"`)
Turbopack's dev-only indexed source maps contain VLQ column deltas with values near 2^32, caused by a signed/unsigned wraparound when encoding negative srcCol deltas on long minified lines. Firefox rejects the map; Chrome tolerates silently. Affects any pre-minified vendor file, not just simple-peer.
