fix(#6250 round-7): anchor Inputs role attribute predicate to full parsed token

PerishCode's round-7 review pointed out that the Inputs group's
role attribute matcher still bypassed the boundary the rest of the
head establishes for other component groups: it matched attribute
values containing 'role=checkbox' text inside unrelated attributes
like [data-label="[role=checkbox]"] and did not reject
:not([role="checkbox"]) properly.

Fix: anchor the regex with ^...\]/i (same pattern that landed on
Buttons and Icons in round-6) so only complete parsed attribute
tokens with a role predicate are admitted to Inputs.

Add regression tests for three cases:
- :not([role="checkbox"]) is not admitted to Inputs
- [data-label="[role=checkbox]"] is not admitted to Inputs
- positive control: [role="checkbox"] still admits to Inputs

Validation:
  pnpm exec vitest run packages/contracts/tests/components-manifest-6250-not-and-attribute-opacity.test.ts
  -> 14 passed (was 11 before, +3 new)
  pnpm exec vitest run  (full contracts suite)
  -> 298 passed (44 files)
  pnpm exec tsc -p tsconfig.json --noEmit
  -> clean
