Add pluggable parser system, perception loop, and project infrastructure

Phase 0 (housekeeping):
- Add .gitignore to protect credentials and runtime files
- Track all project source code, docs, and config

Phase 1 (perception loop):
- Implement pluggable parser architecture (BaseMudParser ABC + ParserFactory)
- Add DeadSoulsParser with regex for HP/MP/SP prompt, room descriptions,
  exits (multiple formats), NPC/item detection, and combat events
- Add OutputBuffer for accumulating text between prompts
- Update GameState with SP support and update_from_prompt/room/combat methods
- Rewire main loop to use parser + buffer for real-time game state updates
- Add reconnection logic to TelnetClient (retry with backoff)
- Remove old TextParser (replaced by pluggable system)
- Add mud_type config field for selecting parser at runtime
- Add comprehensive test suite (50 tests, all passing)
