feat(tui): two-entry /details selector with Tab cycling

DetailsDialog now shows one entry per dimension (Tool cards, Reasoning)
seeded with the current values; Tab cycles the highlighted entry's
pending value (rendered as current -> pending), Enter applies every
changed dimension in one confirm, Esc/Ctrl+C cancels.

 ## Decision
 
-`dsh-tui` registers `/details` beside its other agent-scoped commands. Bare `/details` opens `DetailsDialog`, a centered keyboard selector over the five detail states — the three tool-card phases and reasoning shown/hidden — that preselects the current phase, marks both current values, applies the highlighted state on Enter, and cancels on Esc or Ctrl+C; its width is the `detailsDialogWidth` config key and a second `/details` replaces an open selector, mirroring the `/model` overlay. Arguments name target states directly: `collapsed|expanded|hidden` jumps tool cards to that phase, `reasoning on|off` sets reasoning display, bare `reasoning` toggles it, and directives combine in one invocation. An unknown token returns a command error carrying the usage line. Every entry mutates the same closure state as the shortcuts, refactored so the cycle and toggle are thin wrappers over `setToolsVisibility`/`setReasoning`; the shortcuts and their notices are unchanged.

 A combined invocation applies reasoning before visibility because `setReasoning` rebuilds the transcript from session events, which drops non-durable notice components; applying it last would erase the just-appended visibility notice.

 - A user can jump to any detail mode, set both dimensions at once, and see the current state in the selector — including on terminals that intercept Ctrl+O/Ctrl+R.
 - The parser accepts order-free tokens, so `/details reasoning expanded` toggles reasoning and expands cards; last directive wins per dimension. This leniency is deliberate and documented in the README.
-- The selector applies one dimension per confirm; a combined change still needs the argument form. Enter on the already-current row re-applies it idempotently and repeats its notice.
-- Transcript rebuilds no longer lose assistant messages when a step carries more than one `assistant/message` event; the `details-command` snapshot pins the argument surface and the fixed replay, and `details-selector` pins the open selector with its current-state markers.
+- The selector applies only changed dimensions on confirm, so Enter without a Tab closes silently; a two-dimension change is one open-Tab-Enter interaction.
