feat: convert to workspace and add edgee-compressor crate

Restructure the project as a Cargo workspace with two members:
- crates/edgee-cli: the existing CLI binary (still emits `edgee`)
- crates/compressor: new library crate with tool compression strategies
  extracted from fastly-ai-gateway (bash, claude, opencode, codex compressors)
