🐛 Fix too much recursion when clicking shape in comments mode (#10622)

* 🐛 Fix too much recursion when clicking shape in comments mode

Remove `deselect-all` from `handle-interrupt` in comments mode. The
`select-shape` event emits `:interrupt` which the comments stream
watcher routes to `handle-interrupt`. In comments mode, calling
`deselect-all` cleared the selection and emitted a competing
`rt/nav`, creating a synchronous recursion cycle in the potok store
that overflowed the JS call stack.

Fixes #10620

* 🐛 Add unit tests for comments handle-interrupt

Make `handle-interrupt` public (defn- → defn) and add 4 tests covering
each branch: draft thread, open thread, comments mode, and noop.
