Update blocks from portal-docs, fix Electron/scripts, refresh toolbox

- Pull latest portal-docs resources; regenerate selection-lists, generated_blocks, bf6portal_blocks.json (921 blocks)
- Add 135 missing blocks to toolbox via fill_toolbox_gaps; fix category/type regex in update_blocks_db and fill_toolbox_gaps
- Electron: fix PTY cwd on Windows (HOME/USERPROFILE/homedir), guard ptyProcess before stdout/stderr
- Add tools/update_andy6170_unlimited_variables.py stub for npm run update:andy-vars
- README: note Battlefield Portal Community and new-block support

+- The [Battlefield Portal Community](https://github.com/battlefield-portal-community) org hosts portal-docs (automated docs from [portal.battlefield.com](https://portal.battlefield.com)), PortalScriptingExamples, PortalSDK, and other tools. This editor uses portal-docs; new blocks added by the official Battlefield 6 Portal system are supported via placeholder block registration when importing templates—you can update `bf6portal_blocks.json` and regenerate blocks/toolbox to add first-class support for new block types.
