v0.10.0

Feature release (drop-in over v0.9.x):

• Google OKF v0.1 import/export — tesserae export okf [--import DIR]; lossless round-trip of Tesserae's own bundles.
• Fast transcript search on the tesserae serve sessions dashboard, powered by nicosuave/memex (optional + graceful).
• memex-style read-discipline for MCP — compile_context preview=N + a new get_handle tool page large payloads instead of dumping them into context.
• Extraction quality signals — confidence + confidence_rationale + revisit_signals on session findings, surfaced in fresh_insights.
• Machine-wide setup — tesserae config setup / config deps set global LLM defaults + install optional dependencies once; config llm --reasoning-effort; init offers memex.

All additive; per-project config still overrides the global defaults. pip install --upgrade tesserae==0.10.0
