* fix(routing): basename env URLs and defer writes during node hydration
Encode only env file basenames in ?env= and omit the default file.
Resolve legacy absolute-path bookmarks on load.
Block history writes until the active node matches a cold-loaded remote deep link.
* fix(routing): restore env deep links after stack load hydrates file list
Defer env selection until envFiles is populated after loadFileForRoute.
Apply default env when the URL omits ?env= (Back/popstate).
Document env URL rules and legacy basename resolution in deep-links.mdx.
