feat: add provider limit abort handling for loop runtime

• Provider limit detection: new module detects rate-limit and abort signals during prompt execution, enabling graceful loop termination.
• Abort signal propagation: integrated provider limit checks into the runtime prompt flow with watchdog monitoring.
• Fallback permission patching: subagent sessions in loop worktrees now receive the loop ruleset via a fallback path when session.created events are filtered by instance directory.

feat: add fallback loop permission patching for filtered session.created events

• Refactored single-event hook into LoopPermissionPatcher with ensurePatched fallback called from chat.message and tool.execute.before hooks.
