Add BOT_TOKEN as github_token to Claude workflow

The GitHub App token used by claude-code-action lacks the
`workflow` scope, preventing Claude from pushing changes to
.github/workflows/ files. Pass BOT_TOKEN (a PAT with repo +
workflow scopes) via the github_token input to fix this.

Closes #8, unblocks #9
