Add optional TLS support for the server using axum-server with the
tls-rustls feature. When --server-cert and --server-key are provided
(and tls feature is enabled), the server binds with TLS instead of
plain HTTP.
Changes:
- Add axum-server dependency with optional tls-rustls feature
- New 'tls' feature flag (independent of 'server')
- --server-cert/--server-key CLI args gated behind tls feature
- ServerConfig extended with cert_file/key_file fields
- Conditional TLS/HTTP binding in server mod.rs
- Fix PathBuf::to_str().unwrap() panic risk -> to_string_lossy()
- Update README.md and DESIGN.md with TLS documentation
- Rewrite README.md with comprehensive documentation covering all
features: compression engines, meta plugins, filter plugins, server
mode, MCP integration, and configuration
- Add MIT LICENSE file
- Delete README.org (consolidated into README.md)
- Delete empty PLAN.md
- Update AGENTS.md with current build/test commands and conventions
