Rumdl already appears to have _significantly_ fewer bugs than prettier,
and a solid LSP for editor integration.
The tool is: https://github.com/rvben/rumdl/
I've separated out the change across three commits for easier review.
The configuration tries to match the existing formatting, the changes to
the all the files are to correct issues found by the new tool.

Clang performs the equivalent of Carbon's `lower` progressively,
interleaved with parsing/semantic analysis. This is in conflict with
Carbon's phase-based approach and leads to bugs in missing functionality
in Clang's generated IR during Carbon/C++ interop.
I surveyed other uses of Clang's APIs (originally written up in
[this](https://docs.google.com/document/d/1wi85FRiWh4X9A-gCYMVGKR40-q5fM6-3JaSpePk-XCY/edit?tab=t.0#heading=h.j7j8nwhzao5n)
doc - though the contents in this proposal are now more complete than
the doc) to better understand how Clang's constraints might effect
projects and how they've addressed them. In the mean time, Carbon
changes made more stable approaches viable that were eventually
implemented in #6569.
This proposal then aims to formalize the analysis that lead to #6569 for
posterity in case these design decisions need to be revisited in the
future.
