Bump tigrbl-lens importmap to v0.0.7 and add Lens OpenRPC demo

[cobycloud]

Motivation

• The tigrbl Lens UI failed to hydrate when the importmap pointed to a non-published bundle, so the importmap was bumped to a published release to ensure the browser can load the UI bundle.
• Provide a runnable demo that registers JSON-RPC methods so Lens has real operations to display for manual verification.

Description

• Updated the Lens importmap in pkgs/standards/tigrbl/tigrbl/system/docs/lens.py to use @tigrbljs/tigrbl-lens@0.0.7.
• Updated the integration assertion in pkgs/standards/tigrbl_tests/tests/i9n/test_mountable_lens_uvicorn.py to expect the 0.0.7 import URL.
• Added a demo ASGI app scripts/tigrbl_lens_openrpc_demo.py that defines a Widget model, initializes an in-memory engine, mounts JSON-RPC, mounts /openrpc.json, and mounts /lens wired to the OpenRPC spec.
• Ran code formatting and lint fixes with ruff format . and ruff check . --fix for the affected pkgs/standards packages.

Testing

• Verified package availability with curl against https://esm.sh/@tigrbljs/tigrbl-lens@0.0.7, which returned HTTP 200.
• Ran style/lint checks: uv run --directory pkgs/standards --package tigrbl ruff format . and uv run --directory pkgs/standards --package tigrbl ruff check . --fix, and corresponding tigrbl_tests ruff commands; all succeeded.
• Started the demo server with uv run --package tigrbl --directory pkgs/standards uvicorn --app-dir /workspace/swarmauri-sdk scripts.tigrbl_lens_openrpc_demo:app --host 0.0.0.0 --port 8899 and verified /openrpc.json reported openrpc: 1.2.6 and included methods (7 methods present) and /lens returned HTML containing id="root", the importmap pointing to @tigrbljs/tigrbl-lens@0.0.7, and url: "/openrpc.json".
• Captured Playwright screenshots of /openrpc.json and /lens; the Chromium run crashed in this environment once (SIGSEGV), but the Firefox run completed successfully and produced screenshots with non-empty root content (ROOT_CONTENT_SIZE 19716).
