fix: Address critical issues from PR review

Fix 4 critical issues identified in code review:

**Error Handling Improvements:**
- Replace bare except blocks with specific exception handlers
- Add logging for TimeoutException and ConnectError
- Prevent silent failures in season loading
- Remove misleading "0 episodes" on error

**Robustness Fixes:**
- Add safe None handling in title comparison (main.py)
  Prevents crash when title is None
- Add URL validation before encodeURIComponent (anime.js)
  Prevents crash when anime.url is undefined
- Fix unreachable code in retry logic (recommendations.py)
  Preserve retry context in exception messages

**Changes:**
- animesama.py: Specific exception handling with print statements
- main.py: Safe None handling with (x.get('title') or '')
- anime.js: URL validation before encoding
- recommendations.py: Better exception messages with retry context

All fixes tested and working correctly.
