feat(web-shell): color-code each split pane by workspace (#6971)
* feat(web-shell): color-code each split pane by workspace

On a narrow split (split-screen / mobile), it was hard to tell which
workspace each pane belonged to: a pane's header showed only its session
name, and the sole workspace signal — the composer chip at the bottom —
collapsed to a bare folder icon that looked identical for every
workspace, so the workspace was discoverable only by hovering each one.

Surface the workspace where you actually scan — the pane header — and
give each workspace a stable accent color so panes read apart at a
glance and same-workspace panes read as a group:

- Add a colored workspace tag (dot + basename) at the start of each
  pane header on a multi-workspace daemon, and colorize the header
  divider with the same accent. The dot never shrinks, so panes stay
  distinguishable even when the name and session title ellipsize.
- Derive a stable per-workspace color from the workspace's position in
  the daemon's advertised workspaces[], reusing the sidebar
  session-group palette so the two surfaces speak the same color
  language. Extracted into a shared workspaceAccent.module.css.
- Tint the composer workspace chip with the same accent (folder + faint
  background) so it stays distinguishable even in its icon-only compact
  state, instead of a generic folder.

Single-workspace daemons are unchanged: no tag, and the header divider
falls back to the neutral border.

* refactor(web-shell): address review on split-pane workspace accent

- Rename workspaceAccent.module.css -> WorkspaceAccent.module.css to match the
  PascalCase convention used by every other component .module.css; update both
  import sites.
- Hoist the four raw-hex accent colors (red/orange/yellow/green) into shared
  --accent-* theme tokens in App.module.css, and point the workspace accent
  module, the sidebar group dots, and the overview badges at them. The palette
  now has a single source of truth and can't drift between the four surfaces
  (values are unchanged, so rendering is identical).
- Add a compile-time exhaustiveness guard so adding a
  DaemonSessionGroupPresetColor without extending WORKSPACE_ACCENT_COLORS (and
  its CSS class) fails the build instead of silently dropping that accent.
- Give the pane-header workspace tag role="img" so its "Workspace: <name>"
  aria-label is reliably announced; aria-label on a bare span (generic role)
  is not.

* refactor(web-shell): address follow-up review on workspace accent

- Hoist the four --accent-* tokens out of both theme blocks into the
  theme-independent .app scope, so they are declared once (the values do not
  vary by theme) — a genuine single declaration rather than two kept in sync.
- Add a dev-only runtime check that every accent color has a matching class in
  WorkspaceAccent.module.css, closing the gap the compile-time guard cannot
  cover: CSS modules are typed Record<string, string>, so a renamed/removed
  class would otherwise silently drop that color's accent.
- Rename the "same workspace same color" test to describe what it actually
  asserts (a stable color per cwd, and distinct colors across workspaces).

* refactor(web-shell): address second follow-up review on workspace accent

- WorkspaceIndicator tests: assert on imported CSS-module class names instead of
  string literals, so a CSS-module naming change can't silently make the
  substring checks vacuous; add an expanded-mode (non-compact) accent test so a
  refactor that gated the accent on `compact` would be caught.
- workspaceColor.ts: run the CSS-class contract check unconditionally — throw in
  dev, but console.error in production — so a missing class in a prod build is
  at least diagnosable instead of a silent accent drop.
- WorkspaceAccent.module.css: correct the docstring to state exactly which
  tokens come from where — red/orange/yellow/green from --accent-* in
  App.module.css, blue/purple deliberately reusing the --agent-* brand tokens.

/**
* Per-workspace accent palette, mirrored from the sidebar session-group colors
* so the two surfaces speak the same color language. Each class only sets the
* `--ws-accent` custom property, which the consuming component reads to tint a
* dot, divider, or chip. Shared between the split-view pane header (ChatPane)
* and the composer workspace chip (WorkspaceIndicator) so a workspace looks the
* same in both places.
*
* Values come from shared theme tokens in App.module.css, kept in lockstep with
* the sidebar `.groupColor*` dots and overview `.color*` badges: red/orange/
* yellow/green resolve the theme-independent `--accent-red/orange/yellow/green`
* tokens, while blue/purple deliberately reuse the app's brand tokens
* `--agent-blue-500` / `--agent-purple-600` (which are theme-specific) — so a
* "blue" or "purple" workspace tracks the brand palette and shifts with it by
* design, matching how the sidebar and overview render those two.
*
* Class names deliberately match the `DaemonSessionGroupPresetColor` values so
* a consumer can select one with `accentStyles[color]`.
