Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20Optimize=20readFileSync=20c?=
 =?UTF-8?q?alls?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaced unnecessary `readFileSync(path).toString()` calls with `readFileSync(path, 'utf8')` to prevent intermediate buffer allocations during file system reads.
