feat(Sky): Add missing Electron API stubs and folder URL parameter support

Add three improvements to the Electron workbench:

1. queryLocalFonts stub: VS Code's fonts.js calls mainWindow.queryLocalFonts() to enumerate system fonts. Without this stub, the extension host throws errors. Returns empty array so VS Code falls back to defaults.

2. __name stub: esbuild's keepNames helper used inside VS Code blob workers. Without this, extension host blob workers throw "Can't find variable: __name".

3. folderUri injection: Inline script in Mountain.astro and index.astro parses ?folder= URL parameter and injects it into the workbench configuration, enabling users to open a specific folder on startup.

4. LAND_DEV_LOG initialization: WindPreload now reads LAND_DEV_LOG from localStorage or URL (?devlog=...) parameter to enable selective debug logging.
