v1.3.1

Automatic recall, stress tested. New scripts/selftest.mjs plants facts in synthetic histories of up to 94,472 remarks and asks about them from another session inside long messages: 156 of 156 found, 2 false injections in 360 unrelated prompts, 265 ms per prompt at the largest size. Matching now rests on evidence (rare shared words close together, a repeated phrase, or a ticket id), a recalled line is given to a session once, and only the newest 12 MB of history is searched per prompt. On 345 real prompts recall adds about 105 tokens per prompt on average. Update an existing install with git pull in ~/.claude/claude-code-handover.
