chore: drop unused Swift/Go/C scaffolding

Nothing in this repo or its consumers links against a C library, a Swift
package, or a Go module. Drop the bindings/ subdirs, the build files
(Makefile, CMakeLists.txt), and the manifests (Package.swift, go.mod). Flip
the corresponding flags in tree-sitter.json and ci.yml.

Also bump pnpm/action-setup v4→v6 to finish the Node 24 migration, and
normalize publish-pypi.yml's quote style for prettier.
