perf(#317): collapse redundant existsSync+readFileSync in context-monitor hook (#400)

Browse Source 
Per-PostToolUse hot path did stat-then-read ×3 (config.json, metrics bridge,
warn sentinel); collapsed to read-with-ENOENT-catch (fewer blocking syscalls,
no TOCTOU), behavior identical. Fixes #317.
