We've talked about adding the title to the filename several times over
the years and it seems really valuable. This requires us to compute a
"slug" for the title spelling that can be part of the filename.
Beyond that, we crossed 7000 recently, and so it seems likely that we
will need to add digits sooner rather than later here, so this goes
ahead and moves us to 6 digits so we don't have to adjust again for a
reasonable length of time.
To implement this and ensure we can sustain it going forward this adds a
tool to our pre-commit that validates (and corrects if needed) the
filename.
In order to update everything and keep links working, there are a _lot_
of changes, but the most interesting for direct review are in
`proposals/scripts`.

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.
