Slack CLI v4.5.0

Version 4.5.0 of the developer tools for the Slack platform has landed!

• The Slack CLI now recommends the official Slack plugin to Claude Code users.
• We've reduced the verbose output when using create --app to link an existing app during project creation.
• We've added a --category flag to slack docs search command.
• When the CLI errors because a prompt must be shown while in a non-TTY environment (AI agents, devops scripts, etc.), the error message now displays the prompt and, for app and team selection, the matching flags to select an option.
• We've fixed a recurring unable_to_parse_json error caused by empty JSON files (credentials, config, or app state) left behind by an interrupted write; the CLI now treats them as empty state and recovers automatically.
