0.20.1

Fixed

• Tables keep cells aligned with their columns on worker-rendered frames,
  discover wider rows after scrolling, and retain their widest columns across
  worker and main-actor frames (STUI-1401).
• Automatic table columns obey the same 65,536-cell limit as fixed columns,
  including hosted discovery, bounding padding for oversized content (STUI-1402).
• Validation scrolling stays aligned after native focus reveals a field,
  including frames that reuse layout, so the complete field and its error
  remain visible in narrow hosted forms (STUI-1409).
• Terminal sessions no longer print unsolicited browser-companion, reader,
  or debug-bundle notices at startup or exit. Explicit reader output and
  deferred runtime issue reporting remain available (STUI-1408).

Tests and documentation

• Add fixed-viewport canvas editing benchmarks and measure gallery tab switches
  and counter clicks individually for interaction-latency evidence.
• Clarify that automatic stable output for CI or non-TTY stdout applies to
  terminal sessions; web-hosted sessions animate by default.
