Adds a sublime-syntax grammar for C3 (no new tree-sitter dependency), embeds it into the syntax packdump, and ships default language and LSP (c3lsp) config so .c3/.c3i/.c3t files are detected, highlighted, and can attach a language server out of the box.

Summary
This PR adds comprehensive support for the C3 programming language to Fresh editor, including syntax highlighting, language configuration, and Language Server Protocol (LSP) integration.

C3 Syntax Grammar (
c3.sublime-syntax): Added a complete TextMate-compatible syntax definition for C3 with support for:$and$$prefixes)@prefix)Language Configuration (
config.rs): Registered C3 as a supported language with:.c3,.c3i,.c3t//LSP Integration (
config.rs): Added Language Server Protocol configuration for C3:c3lspproject.jsonand.gitGrammar Registry (
types.rsandbuild.rs): Integrated the C3 grammar into the editor's grammar registry system for proper syntax highlighting supportImplementation Details
The C3 syntax grammar follows the language reference from https://c3-lang.org/ and includes proper scoping for all major language constructs. The LSP configuration references the c3lsp language server (https://github.com/pherrymason/c3-lsp), which users can install separately.
