fix: allow concurrent subagents and sessions in same workdir

[matdev83]

Summary

Remove the exclusive repository coordinator file lock from AgyAgent.Prompt() to prevent deadlocks when a parent agent spawns subagents in the same workspace directory.

Root Cause

AgyAgent.Prompt() held an exclusive file lock (lock on �gy-workdir-.lock) for the entire duration of each prompt turn. When a parent agent running in workspace W spawned a subagent targeting �gy-cli-acp in workspace W, the subagent blocked waiting for the file lock while the parent agent was blocked waiting for the subagent's response.

Fix

• Remove �.coordinator.Lock around Prompt(). Prompt files and context dumps already use unique per-instance/per-session directories (.go-agy-acp-wrapper///...), and AGY natively tracks conversation IDs per stream/session.
• Add TestAgyAgent_ConcurrentPromptsInSameWorkdir to verify multiple sessions can execute prompts concurrently in the same directory without blocking.
