v0.7.6 — SDK auto-update + broken session recovery

What's new

New

• Weekly SDK auto-update — launchd job runs every Monday at 3am, updates @anthropic-ai/claude-agent-sdk to latest, rebuilds the agent-runner, and restarts GhostClaw only if the version changed. Keeps the SDK current so new models are always available. Logs to logs/sdk-update.log.

Fixes

• Broken session auto-recovery — when a session transcript is missing from disk (e.g. after a data directory wipe or path migration), the SDK returns error_during_execution on resume. The orchestrator now detects this and clears the bad session ID automatically, so the next message starts fresh. Previously required manual DELETE FROM sessions in the DB.
• SDK updated — bumped @anthropic-ai/claude-agent-sdk from 0.2.34 → 0.2.92.
