Homebrew: Trust But Verify

Today's merges center on making Homebrew fail more gracefully and quietly less often — batch installs now survive individual failures, and CPAN's automatic formula updates stop silently deleting data they shouldn't touch. Performance work also landed for cleanup and startup profiling.

Start with batch installs. PR 23525, from Mike McQuaid, fixes a real pain point: if one bottle failed to extract during a multi-formula upgrade or install, the entire run aborted, skipping every remaining formula and cask. Now Homebrew reports that failure, keeps going, and still exits nonzero so you know something…

That same "verify, don't assume" pattern shows up in Patrick Linnane's CPAN work. PR 23529 fixes a quietly dangerous bug: automatic Perl resource updates were replacing an entire resource group and discarding anything that wasn't a CPAN match — silently dropping non-CPAN resources and livecheck blocks. Eight core…

Security-minded tightening continued elsewhere: PR 23528 switches Homebrew's URL reachability check to request headers only instead of downloading a full body it never reads, and PR 23469 restricts uv tool bundling to remote sources only, closing a local-source loophole flagged in issue 23451.

On performance, mrjbq7's PR 23515 targets slow cleanup runs on machines with…
