Debugging tools: better tracebacks with cell links

[jamieray]

Description

Debug cells that failed to run. Sometimes they are using functions defined in other cells, or imported modules.

Suggested solution

Multiple features would be helpful, below:

Alternative

1. %debug magic like Jupyter?
2. More readable tracebacks? Currently traceback has cells named with a hash, I wonder if this could be mapped to the 'cell number' that is displayed e.g. in dependency explorer (and/or if there's an option to toggle display of cell names)

Traceback (most recent call last):
  Cell /tmp/marimo_73071/__marimo__cell_XQaa__output.py, line 1
    f
NameError: name 'f' is not defined

3. Related, maybe better: when there's a traceback, make the trace levels in the notebook clickable to jump to the cell (line?) in question, as seems to already be supported when there's a cycle.
