* fix(ui): give embedded settings sections the shared section rhythm
The agents tab panel hosted settings sections in a bare div, so sections
stacked with zero separation; the bespoke .agents-main margin rule in
agents.css missed the nested tabpanel entirely. Descriptions also pulled
up to 4px under control-height header actions (squeezed Verify/Save rows).
Add a .settings-stack primitive to settings.css for embedded surfaces,
use it on the agent tab panel, delete the page-local margin fork, and let
section descriptions clear action-bearing headers.
* test(agents): export getRuntimeConfigSourceSnapshot from runtime-snapshot mock
Main's checks-node-compact-large shard is red: #126531 routed
provider-model-routes through projectConfigOntoRuntimeSourceSnapshot,
which reads getRuntimeConfigSourceSnapshot, and this suite's explicit
vi.mock factory did not export it (24 failures). Return null so the
projection no-ops and resolvers keep reading the provided config.
* feat(ui): add settings design-language foundation (tokens, settings.css, helpers)
* refactor(ui): move settings workspace shell styles into settings.css
* refactor(ui): migrate all settings surfaces to the unified settings design language
Every settings surface (General quick+advanced schema form, Appearance,
Communications, Automation, MCP, Infrastructure, AI Agents, Channels,
Connection, About, Profile, Model Providers, Plugins, Skills, Skill
Workshop chrome, Devices, Worktrees, Debug, Logs, Activity, Automations,
Sessions, Usage chrome) now renders through the settings-ui helpers and
settings.css: sections as plain uppercase headings outside one flat
group surface, hairline-divided rows, a single toggle/segmented/status
vocabulary, status dots instead of pills, and no cards-in-cards or enter
animations. Deletes the qs-*/cfg-*/config-section-card/account-card/
plugins-row/cron-editor-card/session-badge/agent-pill families and
orphaned shared rules.
* style(ui-docs): format design-system docs
* fix(ui): make activity statusKind lookup exhaustive for consistent-return lint
* fix(ui): address settings design-language review findings
Label-wrapped toggle rows with required accessible names, named selects
and cron form controls, busy-disabled segmented controls with restored
theme-transition anchors, collapsible skill groups, semantic plugin
headings, gateway connected status, paired-devices empty state, logs
subtitle, cron prompt help, and keyboard-accessible session goal
objectives.
* fix(ui): harden settings primitives per review round two
Wrap row action clusters, fully-inset nav focus ring, restore number
steppers in the schema form, cap node capability lines, keep the named
Activity region landmark, and associate cron help text via the row
label.
* fix(ui): skip empty section headings and fix the toggle doc example
* docs(ui): import renderSettingsToggleRow in the settings example
* fix(ui): rename number stepper delta to avoid shadowing
