docs(hub): clarify DF8206 recovery steps

Address review feedback on the wording only, no behaviour change:
remove() is a method on ctx.terminals, not on the session, so both
restart() JSDoc lines said it wrongly; DF8206's fix text now prefixes
the calls with ctx.terminals. the way DF8202/DF8204 do and spells out
the two recovery steps instead of contracting them; the docs page's
Fix section is reworded as a sentence.

 ## Fix
 
-`ctx.terminals.remove(session)` the spent session, then spawn a fresh one via `startChildProcess()` / `startPtySession()` with a new id.
+Drop the spent session with `ctx.terminals.remove(session)`, then spawn a replacement via `ctx.terminals.startChildProcess()` or `ctx.terminals.startPtySession()` with a fresh id.
