Description

The whole of PhysLean needs the MultiGoal linter run on it and all the warnings dealt with.

In particular

[leanOptions]
linter.style.multiGoal = true

should be added to lakefile.toml and the project built with lake build. This will generate warnings, some of which may be from Mathlib, but the ones from PhysLean should be dealt. For example:

   exact h 
   exact h2

should be replaced with:

  · exact h1 
  · exact h2

Contributor guide

Research direction
Add the linter configuration to lakefile.toml, run `lake build`, and fix the generated warnings in PhysLean source files, replacing multi goal syntax with bulleted proofs.
