Reworks the app's Material 3 ColorScheme so the whole UI reads as one family with the picker-palette accent chips, instead of Material-generated grey with vivid chips sitting on top of it. (Companion to a ref-bump in halkyon-learn.)

What changes

HalkyonColorScheme.light() / .dark() are now hand-authored rather than raw ColorScheme.fromSeed output. Every chromatic role is a picker-palette member:

role	light	dark
primary	cobalt `#273EB2` (anchor)	lightened cobalt `#AEB9FF`
secondary	slateblue `#415DF0`	`#B7C0F7`
tertiary	copper `#C44800`	lightened copper `#FFB694`
error	cerise `#BA1E55`	`#FF9EBB`

The neutral ramp carries a deliberate cool, cobalt-tinted undertone — light mode is near-white blues (surface #F7F9FF … surfaceContainerHighest #CDD7EF), dark mode a deep navy-slate. That undertone is the piece that stops the background reading as generic Material grey.

How

Built as fromSeed(seedColor: cobalt, tertiary: copper).copyWith(...): fromSeed still fills the rarely-seen roles (shadow, scrim, the *Fixed set, inversePrimary) coherently off the cobalt seed, and copyWith overrides every role the UI actually shows.

Untouched: the 20-color HalkyonPickerPalette (names, hexes, AA-guarded foregrounds) and the HalkyonExtras status colors (success / warning / info). Those already cohere; this brings the chrome up to meet them.

Tests

The colour-scheme + theme tests are updated to lock the new anchors (primary = cobalt, secondary = slateblue, error = cerise, the cool surface values, and the dark lightened tertiary). Full halkyon_ui suite green (50), analyze clean.

Design was reviewed as a swatch/component preview before implementation; the values here match what was signed off.
