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

Add variant to Application enum in src/types.rs
Create src/analyzers/{agent_name}.rs implementing Analyzer trait from src/analyzer.rs
Export in src/analyzers/mod.rs
Register in src/main.rs
Add tests in src/analyzers/tests/{agent_name}.rs, export in src/analyzers/tests/mod.rs
Update README.md
(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.

Use discover_vscode_extension_sources() and get_vscode_extension_tasks_dirs() helpers from src/analyzer.rs.
