Summary

This PR introduces Transactional File Concurrency Guards, a critical "secret sauce" feature for scaling autonomous fleets where multiple agents might operate on the same filesystem.

Problem

In hierarchical or decentralized fleets (Level 4/5 Delegation), agents often inadvertently create "The Agent War" — where Task A reads a file, Task B modifies it, and Task A then overwrites Task B's changes without realizing they were working on the same resource.

Solution

This change implements a global, fleet-wide file access log (_file_access_log) that tracks which task_id performed which action.

Conflict Proximity Detection: If Agent A reads/writes a file that Agent B modified within the last 10 minutes, the tool automatically injects a Concurrency Warning.
Cross-Task Awareness: Agents are now proactively told when a resource is "hot" (under active development by another peer).
Staleness + Concurrency Correlation: Combines existing single-task staleness checks with multi-task conflict detection for a "transactional" experience.

Impact

This significantly improves fleet stability during parallel sprints. It prevents regressions caused by clobbering edits and nudges agents toward coordination instead of conflict.
