    • Add empty WORKSPACE.bzlmod · 04af270f 
      When bzlmod is enabled and WORKSPACE.bzlmod exists, the content of
WORKSPACE is ignored. This prevents bzlmod builds from unintentionally
depending on the WORKSPACE file.

This exposed some small problems with our clang-cl configuration,
which are also fixed in this change.

    • Fix a corner case in SpyHashState for exact boundaries. · 9a79278a 
      AbslHash allows for piecewise chunks to be streamed incrementally into hash states and requires them to hash identically to one giant stream.  The exact size window for this is an internal details `PiecewiseChunkSize`.  There was an off by one error in this code.  Add tests and fix it.

    • Prevent brace initialization of AlphaNum · 2be67701 
      This was not intended to be supported, and it has resulted in calls as `absl::StrCat({...})`, which are not supported and only work coincidentally for the first 4 arguments due to `absl::StrCat` having overloads that take `absl::AlphaNum` directly for those.

The existing situation prevents modifying the implementations of such functions to alternatives that do not have such overloads for those arguments.

    • Optimize integer-to-string conversions · d5a2cec0 
      The updated code is designed to:
- Be branch-predictor-friendly
- Be cache-friendly
- Minimize the lengths of critical paths
- Minimize slow operations (particularly multiplications)
- Minimize binary/codegen bloat

The most notable performance trick here is perhaps the precomputation & caching of the number of digits, so that we can reuse/exploit it when writing the output.

This precomputation of the exact length enables 2 further performance benefits:
- It makes `StrCat` and `StrAppend` zero-copy when only integers are passed, by avoiding intermediate `AlphaNum` entirely in those cases. If needed in the future, we can probably also make many other mixtures of non-integer types zero-copy as well.
- It avoids over-reservation of the string buffer, allowing for more strings to fit inside SSO, which will likely have further performance benefits.

There is also a side benefit of preventing `FastIntToBuffer` from writing beyond the end of the buffer, which has caused buffer overflows in the past.

The new code continues to use & extend some of the existing core tricks (such as the division-by-100 trick), as those are already efficient.
