bug: scheduler.go silently ignores os.WriteFile error when writing agent run log

Bug: Ignored Error from os.WriteFile in Scheduler

File: internal/scheduler/scheduler.go line 242

Description

In executeAgent(), the log file write result is silently discarded:

os.WriteFile(logPath, []byte(logContent), 0o644)

If the outputs/logs/ directory doesn't exist, the disk is full, or permissions are wrong, the failure is invisible. There's no indication that run telemetry is being lost.

Fix

Check and log the error:

if err := os.WriteFile(logPath, []byte(logContent), 0o644); err != nil {
    fmt.Printf("[scheduler] ⚠ %s: failed to write log: %s\n", agent.Name, err)
}

Impact

Silent data loss for agent run logs. In a governance-focused tool this is especially problematic — audit logs must be reliable.
