Report QuantEM versions and editable installs with one profile call

[bobleesj]

What problem does it solve?

Makes quantem.widget.profile() show editable installs without exposing local paths or doing network work by default.

Example

import quantem.widget as qw

qw.profile()
qw.profile(check_updates=True)  # Optional TestPyPI check

Example output from an editable Mac installation:

quantem.widget  0.0.1rc30
  install       editable checkout
quantem.gpu     0.0.1rc5
  install       editable checkout
torch           2.13.0  device=mps (Apple)
python          3.13.13

What should reviewer(s) do?

Check the profile wording and the opt-in update check.

[github-actions]

• Delete bobleesj/quantem.widget:profile-development-status from its remote if you own it, it is not long-lived, and no other PR uses it.
• Remove the dedicated worktree and local profile-development-status branch after confirming the worktree is clean.
• Fetch electronmicroscopy/quantem.widget and update local main before starting new work.
