fix(tools): formatter bracket rules, LSP compiler diagnostics, vocabulary sync

- ludic-fmt: `rows[i]`, `new []int`, `s[a..b]`, `emit(`, `~x`, list-literal
  and query-tag braces stay tight; member calls hug their paren
  (`Date.new(`, `Prefab.spawn(`); `<< >> & | ^ ~` are operators and
  `&& ||` are not — mirrored in ludic_syntax.h, LudicLexer.kt and the
  TextMate grammar. 149 of 274 tracked sources failed --check before.
- ludic-lsp: `initializationOptions.compilerDiagnostics` / `compilerPath`
  are honoured — on save the document's compilation unit is compiled and
  `file:line: error: msg` is published as a "ludicc" diagnostic (the
  option had been documented but never implemented); the workspace scan
  file is per process; bracket codes spelled as char literals
- Overlay added to LUDIC_PHASES, LudicTokens.kt, ludic-mode.el and the
  grammar (the game uses it; check-vocabulary flagged the drift)
- editors: VS Code snippets/package.json/extension.js (`${workspaceFolder}`
  and `~` expansion, PATH lookup, Apache-2.0, real repo URL), Neovim root
  markers, Helix/Zed/Sublime bin/ paths, Emacs vocabulary, JetBrains
  comments; tools/editors/README.md no longer describes C tooling
- .forgejo workflows clone `${{ github.server_url }}/${{ github.repository }}`
  so a fork or mirror tests itself; the docs publish pushes the same way

 # Ludic for Zed
 
 Zed extensions want a Tree-sitter grammar for highlighting, which this toolchain

 That is enough for Zed: point it at `ludic-lsp` and highlighting, completion,
 diagnostics and formatting all arrive over LSP.
