Subject: [PATCH] fix(web,server): improve runtime error visibility in thread
 error banner

Runtime errors (e.g. malformed local SKILL.md) were truncated twice:
server-side to 180 chars, then UI-side to 3 lines via line-clamp-3.
This made errors like invalid YAML parsing failures nearly unreadable.

- Increase server-side runtime error truncation limit from 180 to 512
  characters to preserve diagnostic detail
- Expand UI error banner from line-clamp-3 to line-clamp-6 so longer
  error messages remain readable without dominating the viewport

Closes #1084
