v3.1.0

What's New

• threadlinking_reindex MCP tool — rebuild semantic index without dropping to CLI (13 tools now)

Fixes

• Lock ordering fix — updateThread no longer holds two locks simultaneously, eliminating deadlock risk under concurrent writes
• Deterministic lock ordering in relate — threads locked alphabetically to prevent A-B vs B-A deadlock

Performance

• Meta index carries counts — threadlinking list reads one small file instead of loading every thread from disk
• Semantic search optimization — loads only matched thread files instead of all threads

Improvements

• CLI contextual error tips — "thread not found" now suggests threadlinking list, etc.
• Duplicate snippet detection — warns on exact-match duplicates within last 10 snippets
• Thread relationships — threadlinking relate / unrelate to link related threads
• Track error logging — hook errors written to ~/.threadlinking/debug.log instead of silently swallowed
• README rewrite — stronger opening hook, MCP tools table
• Plugin version synced to 3.1.0
