luxickandClaude Opus 5.5 3a3fb3b51f Serve delete, move and merge dialogs as htmx fragments
The server renders the dialogs (?dialog=delete|move) and answers a move
that needs confirmation with the merge dialog itself, so the client no
longer builds action URLs or interprets X-Merge-Available. Successful
mutations send HX-Redirect, which hx.js turns into a history replace.
