Simplify plugin installation and runtime loading around package-manager-owned dependencies, with Jiti reserved for local/TS fallback paths.
Also scans npm plugin install roots so hoisted transitive dependencies are covered by dependency denylist and node_modules symlink checks.
- channels: convert Tip prose to component, fix /channels/index link, sentence-case heading
- configure: convert Note and Tip prose to components
- devices: convert Note and Warning prose to components
- models: sentence-case scan/status subheadings
- agents: clean up related links and Title Case body link
two bugs. both squash user model choice silently.
bug 1: applyDefaultModel() unconditional primary: model overwrite.
wizard calls with setDefaultModel=true, provider returns its default
(e.g. openrouter/auto), bam user primary gone. fix: existingPrimary ?? model.
bug 2: applyModelFallbacksFromSelection() phantom primary injection.
when no primary configured, resolvedKey (hardcoded default) written as
primary via nullish coalescing fallback. fix: conditional spread — only
include primary key when one actually existed.
tests for both. closes#70696
