Adding a New Analyzer

Splitrail tracks token usage from AI coding agents. Each agent has its own "analyzer" that discovers and parses its data files.

Checklist

1. Add variant to Application enum in src/types.rs
2. Create src/analyzers/{agent_name}.rs implementing Analyzer trait from src/analyzer.rs
3. Export in src/analyzers/mod.rs
4. Register in src/main.rs
5. Add tests in src/analyzers/tests/{agent_name}.rs, export in src/analyzers/tests/mod.rs
6. Update README.md
7. (Optional) Add model pricing to src/models.rs if agent doesn't provide cost data

Test fixtures go in src/analyzers/tests/source_data/. See src/types.rs for message and stats types.

VS Code Extensions

Use discovervscodeextensionsources() and getvscodeextensiontasks_dirs() helpers from src/analyzer.rs.
