Brain-retro #5 surfaced a correlation: long sessions (≥50 turns) correlate
with discipline drift. Reviewer pass showed regulated rate dropped 19% →
4.5% during a long session.
This commit adds:
• computeSessionLengthBlock(episodes, opts?) — pure function that
groups today's (UTC) episodes by task_id, finds the MAX session_turn
per session, and surfaces sessions with ≥threshold turns (default 50)
in a markdown block.
• Wire-up in renderStatus + main CLI: new "## Длинные сессии" section
inserted between disciplineBlock/activeProjects and costBlock.
• 7 new unit tests (36/36 total green).
Behavior:
• No sessions today → ✅ "Ни одной сессии с >50 ходов".
• One+ flagged → ⚠️ table { session_id, max turn, regulated %, last episode ts }.
• Custom threshold via opts.threshold.
Per memory project_enforce_hard_rules.md: this is an indicator, not a hook;
no blocking, just observability. Owner can decide whether to restart when
regulated % drops in a long session.
