…ght+dark

Replace the 8 theme-bound accent styles with 4 visual "directions" that are
orthogonal to light/dark, so every direction supports both modes. Legacy style
ids migrate to the closest direction, so stored settings keep working.

- theme.ts: THEME_STYLES = slate/carbon/nocturne/amber; drop style->theme
  binding; LEGACY_STYLE_MAP migrates graphite/ember/aurora/midnight/sandstone/
  porcelain/linen/glacier to the nearest new direction
- styles.css: 4 directions x light/dark accent token blocks; three-swatch
  theme cards with per-direction light/dark previews
- SettingsPanel: appearance picker shows name + label + 3 swatches + desc;
  theme and direction now switch independently
- locales: add direction names/labels/descriptions (en + zh)

Self-contained HTML/React+Babel prototype that drove the theme-direction work:
Slate / Carbon / Nocturne / Amber, each with light and dark variants, plus the
streaming transcript, dock split-view, command palette, and settings/history/
trash modals. Kept for design provenance; not shipped in the app.

Visual polish for the management modals; no behavior changes.

History/Trash:
- selection shows a 3px accent bar + soft tint instead of a full ring
- status badges become colored dots (current/open/deleted)
- meta row reflows: status+scope left, turns/time right-aligned
- group titles get a count chip
- replace native <select> filters with segmented count pills

Memory:
- type-colored chips (user/feedback/project/reference) + a left accent
  stripe on each fact card, applied to both the drawer and settings renderers
- instruction-file rows get a file icon, title, path, and scope tag

The CommandPalette component (esengine#3124) shipped but was never imported by App —
git -S confirms it was never referenced, so this completes the wiring rather
than reverting a removal.

- App: ⌘K/Ctrl+K hotkey, paletteOpen state, and PaletteItem[] built from real
  nav actions (new session, history, trash, settings/appearance/memory/models)
  plus a snapshot of recent sessions (resume on enter)
- styles: full .palette* stylesheet (centered modal, dimmed backdrop via
  :has(> .palette), grouped list, active state, footer hints, enter animation)
- locales: palette.* strings (en + zh)

- ProcessCard: a tone-colored sweep bar animates along the bottom edge while
  the card is running (CSS-only, via :has(.process-card__spin); respects
  prefers-reduced-motion). Idle cards are untouched.
- Composer mode bar (auto/plan/yolo): a sliding thumb tracks the active mode,
  measured from the live button so it stays aligned with the variable-width
  labels. Per-mode accent colors move to the thumb; stacking uses source order
  to satisfy the z-index token lint.

Aligns the tab strip with the redesign prototype: a "search · commands ·
open file ⌘K" pill fills the strip after the new-tab button and opens the
command palette on click. Wired through both TabBar render sites (mac chrome
tabs + header). Optional onOpenPalette prop keeps TabBar decoupled.

Matches the redesign: auto/plan/yolo now sits in the composer-meta params
row alongside the workspace picker, model, and effort switchers instead of
on its own line above the input. Pure JSX relocation — the sliding thumb,
per-mode colors, and behavior are unchanged.

Matches the redesign hero: the welcome example prompts now lay out in a
2-column grid (4 suggestions) under the centered logo instead of a single
vertical column. Adds a fourth example (find-and-fix-a-bug) in en + zh.

Brings the workspace dock closer to the prototype's single-column feel:
default tree width 320→288 (ratio 0.25→0.22). Topicbar action buttons
(changes/copy/export) slim from 34px to 30px with tighter padding for a
lighter chip look. Min/max bounds and resize behavior unchanged.

The session list under a project folder now slides open/closed instead of
snapping. Uses the grid-template-rows 0fr→1fr technique (pure CSS, no JS
height measurement) with a content fade, and the chevron rotates 90° on
expand. Children always render so collapse animates too; ContextMenu is
portaled so the overflow:hidden inner wrap can't clip it. Respects
prefers-reduced-motion.

- StatusBar: switch to "label + bold value" stat layout; show model name
  on the left with a green idle dot; remove separator dots; add i18n
  label keys for each stat segment (ctxLabel, cacheLabel, costLabel, etc.)
- Animation system: add shared CSS motion tokens (--dur-*, --ease-*,
  --motion-pop-scale, --motion-rise) and apply enter keyframes to
  popovers, drawers, modals, menus, tooltips, tabs, prompt shelf,
  todo bar, settings pages, and process cards
- Mount transition hooks: add useMountTransition (for panels that own
  their mount logic) and useDeferredClose (for parent-controlled panels)
  with prefers-reduced-motion support; wire into CommandPalette,
  ResizableDrawer, SettingsPanel, and HistoryPanel for proper exit
  animations via data-state="closing"
- Composer: remove the workspace/project switcher popover and related
  workspace management (onPickFolder, onRemoveWorkspace,
  workspaceRefreshSignal) — these move to the sidebar
- Remove NotificationCenter, StreamingIndicator, and the in-app
  notification center store (notificationCenter.ts) — unused features
- Styles: round the mode segment pill (border-radius 999px), smaller
  font, add entrance animations for various overlay surfaces
- i18n: update placeholder hint to include "! shell" in en/zh
