Audit-driven improvements (7 items) to Editable:
- E1 invalid + required props
- morfo: Provider gains data-required/data-invalid + aria-required/aria-invalid;
Input emits data-invalid + aria-invalid.
- soma: opts include `invalid` and `required`; runtime registration + provider
props derivation emits the data-attrs.
- eidos css: risk-border on Input + Control when [data-invalid].
- E2 APG: added `apg: 'https://www.w3.org/WAI/ARIA/apg/patterns/textbox/'` to
morfo — Editable is essentially a textbox swap.
- E3 form integration: new HiddenInput part (morfo + soma + eidos). The Provider
wrapper auto-renders `<EditableHiddenInput>` when `name` is set, so consumers
don't have to compose it manually. Submits value as native form data.
- E4 Control re-export: Eidos namespace now exposes `Editable.Control`,
matching the soma surface.
- E7 submit hover: replaced `filter: brightness(1.04)` with
`--_editable-accent-solid-hover` per color variant. Consistent with the
other triggers' bg+border transition pattern.
- E9 disabled state: added `cursor: not-allowed` + `color: content-disabled`
on Preview/Input/triggers, alongside the existing opacity. Clearer
feedback than opacity alone.
- E10 defaultValue: new prop seeds `value` once via untrack when `value`
is uncontrolled. Same pattern as the recent select.defaultValue.
Demo at /uix/components/editable: switches for invalid/required/disabled,
a Form integration section with native form submit + FormData panel,
and a defaultValue uncontrolled example.
Verified: svelte-check --threshold error → 0 errors / 0 warnings / 4578
files. Soma tests: 3/3 pass.
