v0.3.11 — knowledge-capture rewrite (one note per thread)

Changed

• knowledge-capture skill rewritten with new semantics:
  • Purpose clarified: capture the meaningful context of a Claude Code thread as a single coherent note about where the thread has landed — not a running log.
  • Same-thread detection. The skill now derives a stable session UUID from the JSONL transcript filename (~/.claude/projects/<encoded-cwd>/<uuid>.jsonl) and stores it as thread_id in the note's frontmatter. Subsequent invocations in the same thread find and rewrite the existing note rather than creating a new one.
  • Synthesis, not append. When updating, the skill produces a fresh coherent version that integrates the latest understanding. Superseded decisions are replaced inline; brief prose acknowledges material revisions where relevant. There is no appended changelog at the bottom of the note.
  • Escape hatch. If the user explicitly requests a separate note, the skill skips the same-thread lookup and creates a fresh note without a thread_id.
  • Examples updated with preceding-conversation context, showing both a first capture and a subsequent update in the same thread (a brand design conversation that revises colors and fonts).
