### Ⅰ. Describe what this PR did
Main changes:
1. Enhanced file read exception handling: Added exception classification and
automatic retry mechanism (max 5 times), distinguishing permission errors, file
not found, and IO errors
2. Added runtime file truncation detection: Check every 15 seconds, handle
immediate truncation immediately, support copytruncate log rotation scenarios
3. Optimized fast log rotation handling: Critical rotation events (inode
change/truncation) frequency limit reduced from 10s to 1s, detection interval
optimized from 60s to 15s
4. Improved file not found handling: Continue monitoring when file doesn't
exist, automatically start collection when file is created
5. Optimized resource cleanup: Clean up exception count and truncation check
Maps in cleanFile and close methods
Issues fixed:
- Permanent collection stop due to temporary IO errors
- Data loss in fast log rotation scenarios (30 seconds)
- Excessive delay in file truncation detection (up to 60 seconds)
- Unable to monitor correctly when file doesn't exist
