Feature: add commit filtering to the profiler

[jpnelson]

This surely needs some cleanup, but I wanted to put this out there as a feature suggestion! For our use cases, the profiler is very helpful, but is pretty hard to use when we have multiple hundreds of commits. This adds a filter to it, so you can specify which durations you're interested in looking at:

There's an empty state when you hide all of the commits, so it's clear what's going on:

Some edge cases handled:

• Navigating the commits via the "rendered at" panel should remove the filter. I think this is the simplest way, otherwise we'd need to filter all commits there too, and it gets a bit messy
• Changing the filter sets the first commit in the new, filtered list to the active one

Implementation details

• I used a computed signal for filtered commits, which lets us share the logic for filtering easily
• I broke the FilterPopup into its own component now – I tried to keep it lightweight, but we could abstract the logic into it a bit more if we liked.

Future work

It would be great to be able to filter additional things in or out of the commit timeline in the future so commits can be further searched. Maybe by the count of nodes in the commit?

The diff here is a little weird, but the main change to this file is extracting FilterPopup from it

Love this! This is such a great idea!
