feat(ui): drop the slash and the argument echo from the command row

The web command row renders `title · summary` from one logged command
lifecycle pair, and the two halves were written without knowing about each
other: the title was the dispatched line rebuilt from `command/run` and the
summary was `command/done`'s verbatim text, so every Access-chip pick read
`/permission workspace-write · Permission preset: workspace-write.` — the
command name twice and its argument twice.

The title is now the bare command name (no `/`, no arguments — the summary
already says what the command did), and a command handler's settlement text
never repeats the command's own name, so `/permission` returns `preset
workspace-write`. The row reads `permission · preset workspace-write`, and
the TUI notice still names the preset that now applies. The log is
unchanged: `command/run` keeps its structured name/args split for a richer
registered row.
