cli: add hexai command-line tool and split LSP to hexai-lsp

- New cmd/hexai CLI: reads stdin/arg, prints LLM output to stdout
- Prints provider/model immediately to stderr; summary at end
- Refactor config loader to internal/appconfig
- Update Taskfile to build/install/run both binaries
- Update README with new CLI and LSP names
