fix(design-data): converge key-focus to keyboard-focus state

[GarthDB]

Description

Converges the drifted key-focus state value onto its registry-canonical form
keyboard-focus. registry/states.json already lists key-focus as an alias
of keyboard-focus, but the alias had leaked into 26 tokens' name.state
values (vs. only 3 using the canonical form) plus stack-item.json's
component state declaration.

• packages/design-data/tokens/color-aliases.tokens.json: 22 tokens' name.state → keyboard-focus.
• packages/design-data/tokens/color-component.tokens.json: 1 token's name.state → keyboard-focus.
• packages/design-data/tokens/layout-component.tokens.json: 2 tokens' name.state → keyboard-focus.
• packages/design-data/tokens/semantic-color-palette.tokens.json: 1 token's name.state → keyboard-focus.
• packages/design-data/components/stack-item.json: declared state renamed key-focus → keyboard-focus to match.

Each affected token already carries an explicit legacyKey pinning its
published flat name, so this is a structured-data-only change — no published
legacy token names change.

Related Issue

Closes bead spectrum-design-data-bja (discovered while authoring
stack-item.json in bead 7a5, which had to declare key-focus verbatim to
match existing data and pass SPEC-022).

Motivation and Context

key-focus vs keyboard-focus was drift, not a real semantic distinction:
key-focus is a registered alias of keyboard-focus, and every other
signal (29 of 30 component state declarations, platform-extension termIds,
the accessibility/terminology block referencing WCAG 2.4.7 and
:focus-visible) already points at the canonical form. Only stack-item.json
and these 26 tokens lagged.

How Has This Been Tested?

• moon run design-data:validate — no errors (SPEC-022 component-state-valid
  passes for stack-item); only pre-existing, unrelated warnings remain
  (SPEC-043, SPEC-027 dangling bindings already present at main).
• moon run design-data:legacy-output — regenerated output diffed byte-for-byte
  against a pre-change baseline: identical, confirming legacyKey pinning
  held.
• moon run design-data:roundtrip-verify — Roundtrip OK.
• moon run :test — full workspace test suite (Node + Rust), all passing.
• Changeset linted clean: node tools/changeset-linter/src/cli.js check --fail-on-warnings.

Screenshots (if appropriate):

N/A — data-only change.
