Walkthrough

Adds Go language support to the codebase by introducing the tree-sitter-go dependency, configuring it as a server-external package, registering Go in the parser factory's language switch, and adding Go to the supported languages database seed.

Changes

Cohort / File(s)	Summary
Dependency Setup package.json, next.config.ts	Adds tree-sitter-go@^0.20.0 as a new dependency and registers it in the Next.js serverExternalPackages array for server-side builds.
Parser Integration lib/snippets/parsing/parser-factory.ts	Imports tree-sitter-go (with ts-expect-error) and adds a new "go" case in the language switch to return the Go language binding.
Language Registration prisma/seed/languages.ts	Adds a new Go language entry to SUPPORTED_LANGUAGES with id "go", name "Go", file extension ["go"], and highlight alias "go".
