Display module names instead of full file paths (/home/user/project/pkg/mod.pypkg.mod) in flamegraph for readability.

The issue:

Show module names instead of full file paths — /home/user/project/pkg/mod.py → pkg.mod for readability

As I am on mobile it is hard to review but is it possible to have an option to keep showing full paths? this may help if we want to open the file in an IDE. Or does this change only affect the flamegraph output?

Alternative: show the full path of the selected cell as a footer

Move module name extraction logic from heatmap_collector to shared
module_utils to enable flamegraph to display module names instead of
full file paths.
Display module names instead of full file paths
(/home/user/project/pkg/mod.py → pkg.mod) in flamegraph for
readability.
Users can now switch between module names and file paths using the
toggle in the View Mode sidebar. Module names are concise, while
file paths help locate the exact source file, both are useful
depending on the debugging context.

@picnixz That’s a great idea. I’ve added a toggle that lets users switch between full paths and module names. Toggling it updates both the flamegraph frames and the hover tooltips. This change only affects the flamegraph output. Let me know what you think of the toggle.

Toggling was one solution I had in mind so it is fine! showing full path without toggling as a small footer with a "copy path" if you were to double click the footer would also be an alternative/follow-up improvement.

Otherwise just toggling is great! thanks!
