- Add explicit `regex` parameter to all search strategies for clear regex control
- Remove misleading documentation that suggested fuzzy=True enables regex
- Rename `create_safe_fuzzy_pattern` to `create_word_boundary_pattern` for clarity
- Add `is_safe_regex_pattern` function with ReDoS protection
- Update search behavior:
  - Default: literal string search (regex=False)
  - Explicit: regex search when regex=True
  - Safety: validate regex patterns to prevent ReDoS attacks

Usage for OR searches:
- Before: search_code_advanced("ERROR|WARN") # didn't work
- After:  search_code_advanced("ERROR|WARN", regex=True) # works

Fixes #11
