Session picker and rewind dialog gain a redesigned layout behind an isRedesign switch

What

Two screens gain a redesigned layout, controlled by an isRedesign switch:

• The resume picker, the list you choose a past session from, has a new layout with the title in a frame and non-italic hints. Its rows take isRedesign; with it set, "No code restore" loses its warning prefix and warning colour. Before, it always showed as a warning.
• The rewind dialog, used to go back to an earlier message, passes isRedesign to its rows. In the redesign it hides the heading text and the footnote. The note "Rewinding does not affect files edited manually or via bash." now comes from shared text.

In one place the picker passes isRedesign: !1, which means false, and nothing was found that turns it on.

Also changed:

• The message shown when resuming after compaction (shrinking earlier conversation to free room) now includes toolNamesUsed, the names of the tools that were used.
• The fullscreen-renderer prompt can take custom text.
• In the Artifacts list, the delete-confirm mode gains a click that resets the confirmation.

Why

A visual refresh of these screens is in the build, but until something turns the switch on you may see no change to them. The compaction resume message now tells Claude which tools had been used.
