feat(web): deepen composer stroke to l2, widen menu radii to 20px

The composer hairline moves one step up from the menus' l1; the seven
menu-fill dropdown cards grow from 16px to 20px corners. Notes and the
token comment record the new layering.

 `gradient-shadow-text.css` (the ui-theme shadow owner) defines the elevation tokens beside the `--dsw-shadow-lv*` scale:
 
-- `--dsw-elevation-stroke-color` — the hairline color, defaulting to `--dsw-alias-border-l4` (black 16% light, white 20% dark); components rebind it per surface or state, and every menu-fill surface (`--dsw-specific-menu` background) and the composer rebind the lightest `--dsw-alias-border-l1`, both quieter than panels and buttons. The default is declared on `body` alone while the derived tokens below are re-declared on `body, body *`: a custom property computes with `var()` already substituted, so body-only derived tokens would bake in body's color and make every rebind a no-op (the same per-element re-substitution scrollbar.css states for `--dsh-scrollbar-thumb`).

 - `--dsw-elevation-panel` / `--dsw-elevation-prominent` — the stroke plus two faint soft layers (3px directional + 16/20px glow at 2–5% black), panel for small floating widgets and cards, prominent for floats, and soft — larger blur at lower alpha — for the composer.
 
-Converted surfaces set `border: 0` and one elevation shadow: every `--dsw-shadow-lv3` float (Menu, Modal, popup selects, model select, usage/context popovers, feedback actions, schedule/job popovers, subagent lineage, settings panel, cordis panel, experimental team panel) takes prominent, and the lv2 surfaces (scroll-to-bottom button, turn-preview card, attachment-rail arrows, question composer, trajectory tooltip) take panel. The composer card takes the soft tier with the l1 stroke rebind, and its workspace-trigger state sets the stroke color `transparent` instead of the former `border-color: transparent`. Dark theme needs no shadow overrides: the soft layers are near-invisible there and the stroke carries the separation, as in Codex.

 `packages/client/ui-theme/tests/elevation-styles.client.spec.ts` pins the token composition and scans every stylesheet under `packages/`: a rule pairing an lv/elevation `box-shadow` with a `--dsw-alias-border-*` border fails, and every `solid` border on a neutral `--dsw-alias-border-*` token must be `0.5px` wide. Deliberate keeps: Toast and HoverCard (inverted fills where a theme-following stroke is meaningless), ImageLightbox (bare image), and the warn-bordered approval/plan panels, whose state-colored borders stay real borders and pass the scan.
