jview v0.20.1

jview 0.20.1 — smarter map detection in the type overlay.

✨ Improvements

• Maps are now detected by key shape, not just values — and key types are
  inferred. Previously a small numeric-keyed dictionary like
  {"8960": [...], "8970": [...]} was treated as a record, and when such a map sat
  inside many records, merging exploded every key into 6550?: number[] // 0%
  noise. Now, if most keys aren't identifiers (numeric, delimited like DNSE|STOCK,
  dotted, …) and the values are homogeneous, it's a map regardless of entry count —
  while a small record with real field names ({x, y, z}) stays a record. The key
  type is inferred too: Record<number, T> when every sampled key is numeric, else
  Record<string, T>. A numeric-keyed map nested in thousands of records now
  collapses to a single Record<number, number[]> on merge.
