Plugin composer pills with a menu or popover now show an upward chevron at
every width, so a pill that opens a surface reads differently from a one-tap
action pill. Built-in Tasks and Subagents pills are unchanged.
The transcript's bottom inset used to be reserved only while some pill
existed. Plugins that add pills when a turn ends and remove them when the next
starts moved the transcript every turn. The inset is now reserved whenever the
agent has an active composer.
* feat(plugins): unify source installation and simplify plugin settings
* feat(plugins): install npm sources and review CLI updates
Treat install selectors as one-time choices. Keep source identity separate from the installed revision, and resolve ordinary updates from the current upstream default. npm only acquires directories; plugin loading remains independent of npm.
* fix(plugins): preserve CLI diagnostics and exercise reviewed updates
Move new source capability coverage to real browser journeys. Update the requirements regression to exercise preview and apply, and preserve the existing duplicate-selector diagnostic across positional option scopes.
