[WIP] Prim publishing

[Rider-Linden]

Work in progress,

Handles new launch method from viewer and supports "prim publishing" by viewer.

Presents prims as files directories on the explorer pane. Allows read, write and limited script creation.
See Message_Interface.md for description of JSON-RPC protocol with viewer.

Viewer side PR:
secondlife/viewer#5834

Pull request overview

Adds initial support for “prim publishing” by integrating new viewer JSON-RPC methods and exposing published in-world object inventory as a browsable sl://objects/... virtual filesystem inside VS Code, plus a viewer-driven vscode://.../connect launch flow.

Changes:

• Introduces ObjectContentService + ObjectContentProvider to model published objects and implement a VS Code FileSystemProvider for sl://objects.
• Extends WebSocket/JSON-RPC client and SynchService to handle object.publish / object.unpublish / object.update notifications and new object content RPC calls.
• Registers URI handler + file decorations + resource label formatting to improve UX for viewer launches and disconnected state.

src/extension.ts:120

• connectToViewer returns a Promise but is called without await/void and without error handling. If setupConnection throws (e.g., unexpected failure paths), this can surface as an unhandled promise rejection. Consider void synchService.connectToViewer(...).catch(err => showErrorMessage(...)), or make handleUri async and await with try/catch.

                logInfo(`Connecting with port=${port}, object_id=${object_id ?? "(none)"}, script_id=${script_id ?? "(none)"}`);

                synchService.connectToViewer({ port, object_id, script_id });
            }

doc/Message_Interfaces.md:910

• ObjectItemCreateParams.vm is documented here as "luau" | "lsl", but the code/interface uses ScriptVM = "lsl2" | "mono" | "luau" and the provider sends "lsl2" for .lsl creation. Update the doc to match the actual accepted values.

  prim_id: string;           // UUID of the prim to create the item in
  name: string;              // Pure SL inventory name — no file extension
  type: InventoryItemType;   // "script" ("notecard" reserved for future)
  vm: ScriptVM;              // Required for scripts: "luau" | "lsl"
