Homebrew distribution: failed to spawn `codewhale`: codewhale not found on PATH or in sibling directory.

Description

I updated deepseek-tui/codewhale via homebrew as follow:

brew update
brew upgrade

And when I tried to start deepseek-tui/codewhale, the following shows:

cytosine@ComputeCyto ~ % deepseek
warning: `deepseek` is deprecated; run `codewhale` instead. This alias will be removed in v0.9.0.
error: failed to spawn `codewhale`: codewhale not found on PATH or in sibling directory. Is it on PATH? Install with `cargo install codewhale-cli` or via npm/Homebrew.
cytosine@ComputeCyto ~ % codewhale
zsh: command not found: codewhale

I tried to reinstall deepseek-tui/codewhale but it seems to be a recurring problem

Steps to reproduce

1. update/install codewhale via homebrew on mac with apple silicone;
2. And try to run codewhale or deepseek

Expected behavior

It should run

Actual behavior

It is not

Impact

It blocks my dev of course

• codewhale version: 0.8.44
• Install method: homebrew

I tracked down the root cause: the Homebrew formula at .github/scripts/update-homebrew-tap.sh downloads the deepseek-* legacy shim artifact instead of the codewhale-* dispatcher. The legacy shim prints a deprecation warning and tries to spawn codewhale, which was never installed by the formula. Working on a PR to fix this.
