Resource optimizations, Go 1.25, remove IDNA library, add benchmark CI

[wolveix]

This PR:

• Adds a benchmark step to the pull request CI + added many benchmark functions
• Fixes form data memory leak (Memory leak while using huma.MultipartFormFiles[T] #902)
• Removes IDNA external library and therefore idn-hostname format support (aliased to hostname format support for the time being)
• Upgrades Huma to Go 1.25 + ran go fix (since 1.26 released last week, 1.25 is the lowest supported version)
• Various library optimizations:
