* feat(acp): flatten Zed-style grouped configOptions choices
DeepSeek Harness 0.2.x (and Zed-style agents generally) nest select
choices one level under group entries that carry no `value` of their
own:
options: [{ group, name, options: [{ value, name }] }]
Both the per-session config-option descriptor and the model-metadata
merge previously read only flat `{ value, name }` entries, so grouped
pickers surfaced zero choices. Flatten recursively in a shared helper;
flat options are unaffected.

* feat(dsh): runtime model switching through ACP config options
dsh advertises its model catalog as a Zed-style grouped config option
(provider groups with JSON-encoded provider+model tuple values) instead
of session/set_model, so wire it through the generic config-option rail:
- shared: ListDshModels/ListDshModelsForMachine RPC methods, response
types, and grant dsh the ModelChange flavor capability
- cli: DshMode becomes {model} and rides the queued-batch mode like
other flavors; the launcher applies model switches per-turn via
session/set_config_option, discovers the live current model from the
config option after newSession, rolls back (and warns) when a switch
is rejected, and serves ListDshModels from session metadata. A
machine-scoped probe (60s single-flight cache) backs the new-session
catalog; --model is now accepted by the dsh command
- hub: dsh-models passthrough routes (machine + session scope)

* feat(web): dsh model selector for new sessions and in-chat switching
New-session form gets a Default-plus-catalog picker fed by the machine
probe (opaque tuple values verbatim, friendly names as labels, stale
draft picks dropped when the catalog rotates). Running sessions get the
same catalog over the session-scoped hook; switching rides the existing
generic model-change path now that dsh advertises ModelChange.

* fix(dsh): honor explicit Default reset and cover pending catalog discovery
The launcher now captures the server default before applying any spawn
override, and a queued `model: null` (the picker's "Default" after an
explicit switch) switches back to it instead of silently keeping the
last applied model; DshMode keeps null distinct from undefined all the
way from the config RPC through the queue (runDsh no longer collapses
it). The web model-option helpers get explicit dsh branches mirroring
opencode: pending, failed, or empty ACP discovery renders no Claude
presets and the Ctrl/Cmd+M cycler keeps the current model. NewSession
restores dshSelectedModel from preferred launch settings alongside
agy/opencode (the existing catalog-validation effect drops stale tuples)
with remount, forward-on-create, and fallback tests.

* fix(dsh): keep unset model preferences distinct from Default resets
Two review follow-ups:
- currentModel collapses "no preference yet" into null, so a session
started without --model on a server that reports no current model
queued model:null on every ordinary turn — the launcher read each one
as an explicit "Default" reset and emitted 'Cannot reset the DSH
model' every turn. The preference is now three-state (undefined =
nothing requested, null = picker's explicit Default, string = model),
encoded through dshModeForPreference() so preference-less turns carry
no model field at all.
- ListDshModels was registered only after initialize/session/new and
discovery finished; a picker opened during startup hit an
unregistered-method rejection with no retry path and stayed empty
until remounted. The handler is now registered before initialization
and parks on a readiness promise resolved once the session exists and
discovery has settled (rejected with the startup error otherwise).

* docs: DSH advertises model selection over ACP
The capability blurbs still said HAPI exposes no model pickers for DSH and
that the ACP server has no model switching. Update them to the wire reality:
models are listed via ListDshModels and applied per turn with
session/set_config_option. Resume remains out of scope on this branch.
