Remove legacy dev config and consolidate to Eglot-based setup

- Delete emacs-dev-config.el (650 lines of legacy lsp-mode config)
- Update emacs-dev-config-modern.el to use Company instead of Corfu
- Remove legacy config loading from init.el and init-utils.el
- Update CLAUDE.md documentation to reflect new architecture

New structure:
- init-eglot.el: LSP support (auto-enables for programming modes)
- emacs-dev-config-modern.el: Optional extras via M-x enable-dev-mode-modern
- init-completion.el: Company completion (single source of truth)
