Fork-only infrastructure for lab testing of FIDO2/WebAuthn work. Not intended for upstream. - Trans flag gradient app icon (AppIcon-Fork) with "LAB" banner to visually distinguish fork builds from upstream cmux - generate_fork_icon.py: recolors debug icon banner to trans gradient (light blue #5BCEFA → pink #F5A9B8 → white → pink → blue) - fork-ci.yml: build validation for macOS .app, Linux daemon, nix flake - fork-release.yml: multi-platform release workflow producing: - macOS DMG (.app bundle with LAB branding) - Linux cmuxd binaries (amd64, arm64) - DEB packages (Debian/Ubuntu) - RPM packages (RHEL/Fedora) - flake.nix: Nix flake for darwin .app packaging and dev shell

The upstream ghostty commit (ae3cc5d) doesn't have our fork's Linux platform variant (PRs #1-#8 on Jesssullivan/ghostty). cmux-linux requires GHOSTTY_PLATFORM_LINUX from the fork. The ghostty fork needs a separate rebase onto upstream before we can update the submodule pointer. Keep our fork commit for now.

Update ghostty submodule to Jesssullivan/ghostty@620ecaebb which has: - manaflow-ai/ghostty base (ae3cc5d): upstream APIs (clear_selection, select_cursor_cell, config_path_s, bool read_clipboard callback) - Our 8 Linux PRs (#1-#8): GHOSTTY_PLATFORM_LINUX, OpenGL fixes, renderer backend imports Also update onReadClipboard return type to bool (matches new ghostty).

The Ghostty upgrade made paste_from_clipboard a performable binding. In performKeyEquivalent, the !isPerformable guard prevented the menu from handling Cmd+V, so keyDown was called directly. Inside keyDown, interpretKeyEvents triggered paste: (clipboard request #1) and then ghostty_surface_key fired the same binding (clipboard request #2), causing a double-paste race that corrupted the output. Remove the !isPerformable exclusion so performable bindings like paste also try the Edit menu first, restoring the single-request flow.
