Error message using unclear cell identifier instead of cell number

### Describe the bug When I try to run a cell whose ancestor raises an exception, I get the following message: ``` Ancestor raised: An ancestor raised an exception (NameError): (raised in cell: 918d2406-014b-4a20-9c9a-ba8cb7ab2ba2) ``` How do I know which cell this is referring to? Is it possible to change error messages like this one to have the number of the cell raising the error and possibly a hyperlink for easier discovery? ### Environment <details> ``` marimo VS Code Extension Diagnostics ===================================== Language Server (LSP): UV Bin: Bundled (/Users/albi/.vscode/extensions/marimo-team.vscode-marimo-0.13.3-darwin-arm64/bundled/libs/bin/uv) UV: 0.11.3 (45da18ac3 2026-04-01) ✓ Using bundled marimo-lsp via uvx Python Extension: Interpreter: /Users/albi/.cache/uv/environments-v2/analysis-slide-4a-7e7dcfc4bd200a5b/bin/python Version: 3.14.3.final.0 Environment: VirtualEnvironment (analysis_slide_4A.py (3.14.3)) Python Language Server (ty): Status: running ✓ Version: 0.0.26 (940305127 2026-03-26) Binary: UvInstalled (/Users/albi/Library/Application Support/Code/User/globalStorage/marimo-team.vscode-marimo/libs/bin/ty) Python: /Users/albi/.cache/uv/environments-v2/analysis-slide-4a-7e7dcfc4bd200a5b/bin/python (3.14.3.final.0) Ruff Language Server: Status: disabled Reason: Ruff extension (charliermarsh.ruff) is not installed.
