A thin LSP client that spawns `testium lsp` and forwards messages to
VSCode. All language intelligence lives in the testium repo, so this
extension only needs republishing for editor-side UX changes.
- package.json: declares the .tum language, registers the LSP client,
exposes testium.serverPath and testium.trace.server settings.
- src/extension.ts: vscode-languageclient setup over stdio, surfaces a
user-visible error if `testium lsp` can't start.
- syntaxes/tum.tmLanguage.json: TextMate grammar embedding source.yaml
plus tum-specific tokens for $(name), <| python |>, {% jinja %},
{{ jinja }}.
- language-configuration.json: comment char, bracket pairs, auto-close
for $(/), <|/|>, {%/%}, {{/}}.
- README.md: install (incl. testium[lsp] extra), settings, packaging
via vsce, publish to both VS Marketplace and Open VSX (the latter
is what VSCodium / Cursor / Gitpod use — same .vsix artifact).
Works identically on VSCode and VSCodium — no Microsoft-proprietary
API surface used.
