+-- TODO: ansible role navigation
+-- When gd is pressed on a role name (e.g., "caddy", "geerlingguy.docker"),
+-- open that role's directory in oil.
+--
+-- Implementation approach:
+-- 1. Find ansible root by searching upward for ansible.cfg (bounded by getcwd)
+--    - If not found, fallback to searching for .git directory
+--    - If neither found, show warning and do nothing
+-- 2. Parse roles_path from ansible.cfg
+--    - Split by ':' to get multiple directories
+--    - Resolve relative paths against ansible root
+-- 3. Check if word under cursor matches any role directory
+--    - Search each role directory for matching subdirectory
+-- 4. If match found: :Oil <role_path>
+--    - Else: fallback to vim.lsp.buf.definition()
+--
+-- Key functions to implement:
+-- - find_file_ascending(start_dir, filename, boundary_dir)
+--   Search upward for a file (e.g., ansible.cfg), stopping at boundary_dir
+--
+-- - find_directory_ascending(start_dir, dirname, boundary_dir)
+--   Search upward for a directory (e.g., .git), stopping at boundary_dir
+--
+-- - get_ansible_root(buf_path)
+--   Return the ansible project root directory by searching for ansible.cfg
+--   or .git directory
+--
+-- - parse_roles_path(ansible_root)
+--   Parse ansible.cfg to extract roles_path configuration
+--   Return list of absolute role directories
+--   Fallback to ansible_root .. "/roles" if roles_path not in config
+--
+-- - find_role_path(role_name, role_dirs)
+--   Search each role directory for a matching subdirectory
+--   Return full path if found, nil otherwise
+--
+-- - ansible_gd()
+--   Main function bound to gd keymap
+--   Get word under cursor, find role path, open in oil or fallback to LSP
