Subject: [PATCH] fix(swift): move tree-sitter-swift to optionalDependencies
 and use conditional imports

The PR merge reverted the Swift install fix. tree-sitter-swift must be
in optionalDependencies with conditional createRequire imports, otherwise
npm install fails on systems where the native build can't succeed.
