displayModel gains a `config` source, ranked below any report from the running
CLI and above the launch model: custom endpoint, then statusline or screen,
then config, then launch, then nothing. The screen still wins whenever it
names a model, since that is what the running TUI uses.
- Registry data: capabilities.modelDetect gains `configResolver`, a NAMED
reader (src/model-config-resolvers.ts), like a launcher profile; dsh names
'deepseek-route' (the reader from the previous commit). `screenLine` becomes
optional; the schema refuses a modelDetect naming nothing, an unknown
reader, or screenLines without a screenLine.
- Session: the reader runs from _withPaneLifecycle's finally, so at every pane
start, attach and relaunch, with the session's own launch config
(legacyConfigForMode) and env (its clamped overrides, then the server's), so
a per-session DSH_HOME is the home read. Async; a read that lands after a
newer one or after the session stopped is dropped; a remote or docker
session reads nothing locally. A change emits displayModelChanged
(broadcast and persist). Not restored after a restart: the next attach
reads it again, and a restored screen value outranks it.
