Power Toys: BackChat moves in, keyboard shortcuts, 17.1 and 17.2

Repo: Jumoo/umbraco.community.powertoys

Brought BackChat into Power Toys as three power toys: BackChat chat, Tasks, and content reviews with reminders (#60, #61, #62); archived the old Jumoo/BackChat repo
BackChat and Tasks panels now dock beside the page, like the Umbraco.AI Copilot sidebar
Review check interval now applies without a restart
Released 17.1.0 and wrote the BackChats back blog post
Added screenshots to the BackChat and Tasks docs
New Keyboard Shortcuts power toy: ? or a header button opens a docked panel listing the shortcuts on the current screen, read live from Umbraco (#68)
Custom site-wide shortcuts: go to a section or URL, open search or a panel, run a workspace or entity action; Alt+1–9 go to sections by default; added and edited in their own sidebar (#70)
Released 17.2.0 and added a keyboard shortcuts section to the blog post
