docs: correct the Homebrew install command

[cardmagic]

Found while auditing rubyclassifier.com, where the site had it right and the README had it wrong.

The formula moved to homebrew-core, and cardmagic/homebrew-tap no longer carries it:

$ brew install cardmagic/tap/classifier
Error: No available formula or cask with the name "cardmagic/tap/classifier".
==> Searching for a previously deleted formula (in the last month)...
cardmagic/tap/classifier was deleted from cardmagic/tap in commit 09c4db3

cardmagic/homebrew-tap/Formula now holds only messages.rb, notes.rb, and reminders.rb.

The plain name resolves through homebrew-core and works:

$ brew info classifier
==> classifier: stable 2.6.0 (bottled)
Text classification with Bayesian, LSI, Logistic Regression, and kNN
https://rubyclassifier.com

Fixed in README.md and docs/cli.md.

Note: homebrew-core is at 2.6.0 and has not yet picked up the 2.7.0 release from today.

Verified: 761 runs / 0 failures, static doc checks pass.

Greptile Summary

Corrects the Homebrew installation instructions to use the formula now available from homebrew-core.

• Replaces the obsolete tap-qualified command in README.md.
• Applies the same correction to the CLI documentation.

Confidence Score: 5/5

The documentation-only correction appears safe to merge.

The two changed examples consistently replace an unavailable tap-qualified formula with the working homebrew-core formula name, with no blocking or non-blocking issues identified.

Important Files Changed

Filename	Overview
README.md	Updates the Homebrew installation command from the removed custom tap formula to brew install classifier.
docs/cli.md	Keeps the CLI installation documentation consistent with the corrected Homebrew command.
