v0.9.7 — Grok Agent Support

What's new in v0.9.7

Grok is now a first-class fourth agent peer alongside claude, agy, and codex.

Added

• Grok agent registration — AGENT_CAPABILITY_BASELINES["grok"], discovery path ~/.grok, version probe via grok -v
• GROK.md instruction file — managed by synlynk with synlynk:start/end markers; Co-Authored-By: Grok <noreply@x.ai>; injected via --rules at exec time
• Init wizard — synlynk init --agents claude,agy,codex,grok creates GROK.md; grok now in the default agent set
• Exec context injection — synlynk exec grok prepends --rules GROK.md; headless (-p) mode also injects --rules .synlynk/context.md
• Dispatch — --always-approve for non-interactive dispatch; --permission-mode bypassPermissions fallback via agent profile; --output-format json for token extraction
• Token extraction — nested usage.input_tokens/output_tokens JSON pattern for Grok structured output
• Model version extraction — tier-2 path reads .agents/grok.json → "model" field

Fixed

• Stale time-sensitive fixture in test_collect_capability_drop_returns_finding
