Root cause: VS Code commands (acceptAgentStep, terminalCommand.run etc)
return undefined silently but don't actually accept WAITING steps.
LS requires HTTPS + CSRF token for RPC calls.
New approach: Phase 1 tries SDK rawRPC (has CSRF auth) with
HandleCascadeUserInteraction + ResolveOutstandingSteps.
Phase 2 tries all VS Code commands as fallback.
All results logged to bridge/extension.log for debugging.
Also removed stall detection (fundamentally broken — stepCount
keeps incrementing from other tool calls during WAITING).
