fix: resolve CI type checking issues

- Add return type annotations to __hash__ (-> int) and __eq__ (-> bool) in HistoryEntry
- Add TextIO import and type annotations for file parameters
- Add type ignore comment for fuzzywuzzy import
- Add HistoryEntry import and list type annotations in time_analysis
- Add assert statements for Optional[datetime] timestamps
- Add TypedDict classes for type-safe pattern dictionaries
- Add CommandPattern import and list[CommandPattern] type annotation
- Add -> None return types to all test methods
- Remove unused HistoryEntry import (F401)
