hvolt for VS Code

ArkTS support for hvolt projects.

Requires hvolt 26.0.0 or newer (the first release with hvolt lsp --stdio).

• Syntax highlighting: TypeScript comes from VS Code's built-in source.ts grammar; the ArkTS additions (decorators such as @Entry/@State, the struct keyword, $r(...) resources, ArkUI components) are defined in syntaxes/ets.tmLanguage.json.
• Language server: hover, completion, definition, signature help and rename, with semantics from the TypeScript build inside the installed SDK — no DevEco Studio needed.
• Diagnostics from the real toolchain: codelinter on save, plus build errors mapped onto the files that caused them.
• hvolt.toml: key completion per section, route completion inside router.pushUrl(...), validation (unknown keys, missing route files), and navigation from a dependency to its module.
• Commands: Build, Build+install+launch, Sign, Install on device, Screenshot, Fetch log.

Requires hvolt on PATH (or set hvolt.binaryPath) and an installed SDK (hvolt sdk download <version>).

The server can also be driven by any other LSP client: hvolt lsp --stdio.
