feat: Implement resume strategy engine and session content parser

- Added `resume-strategy.ts` to determine optimal resume approaches including native, prompt concatenation, and hybrid modes.
- Introduced `determineResumeStrategy` function to evaluate various resume scenarios.
- Created utility functions for building context prefixes and formatting outputs in plain, YAML, and JSON formats.
- Added `session-content-parser.ts` to parse native CLI tool session files supporting Gemini/Qwen JSON and Codex JSONL formats.
- Implemented parsing logic for different session formats, including error handling for invalid lines.
- Provided functions to format conversations and extract user-assistant pairs from parsed sessions.
