- The mapstructure library is no longer needed for direct duration
parsing since we now store TTLs as string durations (e.g., "15m",
"168h") and parse them on demand via helper methods.
- This allows more flexible duration formats in configuration and moves
the parsing responsibility to the JWT config struct itself.
Add initial project structure including:
- Go module with Cobra CLI dependency
- Root command and main entrypoint
- Basic documentation (README, AGENTS.md, architecture, decisions,
development, roadmap)
- Configuration example and gitignore
- Tool version management with mise
- Comprehensive project rules and conventions
