Based on my search, I found one potentially related PR:

Related PR:

• fix(nix): handle missing .bun directory in canonicalize-node-modules #12636 - fix(nix): handle missing .bun directory in canonicalize-node-modules
  • fix(nix): handle missing .bun directory in canonicalize-node-modules #12636
  • This appears related because PR fix: revert "feat(app): add web input focus shortcut (#12493)" #12639 mentions fixing the node_modules path and switching back to an isolated install, which could be addressing similar issues with the Nix/bun setup

However, this is not a duplicate PR—it's a separate fix addressing a related build/installation concern. PR #12639 is specifically reverting the web input focus shortcut feature due to unintended side effects on the build system, while #12636 fixes a specific Nix issue.
