[RPA Workflows] bug: rpa-tool IPC unsupported on Studio 25.10.6, no upgrade path available

[Pranav-Work26]

What happened

All uip rpa ... --use-studio commands fail with "Studio 25.10.6 does not support rpa-tool" when using the uipath:uipath-rpa-workflows skill. The error message instructs the user to upgrade to the latest version of UiPath Studio, but:

1. No minimum Studio version is documented in the plugin reference docs — users don't know what version they need.
2. The error message says "upgrade to latest" but doesn't specify a target version number.
3. Studio 26.x is not available for download through the user's Automation Cloud tenant, making the upgrade impossible and the plugin completely unusable.

This effectively blocks the entire RPA Workflows skill — XAML generation (get-default-activity-xaml), validation (get-errors), activity discovery (find-activities), UI target configuration (uia subcommands), indication (indicate-element/indicate-application), and execution (run-file) all require --use-studio and all fail with the same error.
