refactor(picker-shell): close as INTERNAL primitive (audit P1 #5)

picker-shell quedó suelto en el audit-codex: existía un morfo placeholder
en src/uix/morfo/components/picker-shell.ts sin imports, sin events,
sin texts, y los 5 composite pickers (date / date-range / time /
time-range / color) consumían eidos parts via re-export bajo SU namespace
(<DatePicker.Footer>, etc.) — apps nunca escribían <PickerShell> directo.

Cierre como INTERNAL primitive per la propia recomendación del audit:

- Movido src/uix/morfo/components/picker-shell.ts → src/uix/morfo/internal/picker-shell.ts.
  El audit walk de morfo/components/ ya no lo encuentra. Cero imports
  rotos (no había ninguno).
- README en src/uix/eidos/components/picker-shell/README.md declara
  el status INTERNAL + diagrama de composición de los 5 pickers.
- Docstring del morfo actualizado con STATUS: INTERNAL explícito.
- audit-codex-full-1.md sección 5 marcada RESUELTO con verbatim del cierre.

Verificación:
- npm run morfo:vocabulary → EXIT 0
- npx vitest src/uix/sema src/uix/morfo → 195/195 pass
- npm run component:audit → picker-shell ya no aparece (no era public
  component, no debe figurar en lista de NEEDS-WORK)

+# PickerShell (INTERNAL primitive)
+
+**Status:** Internal layout primitive. **Not a public component.**
+
+PickerShell is the shared layout chrome used by the five composite pickers:
+
+- `DatePicker`
+- `DateRangePicker`
+- `TimePicker`
+- `TimeRangePicker`
+- `ColorPicker`
+
+Each of those re-exports the picker-shell parts under its own namespace, so apps write `<DatePicker.Footer>` / `<ColorPicker.Clear>` / etc., never `<PickerShell>` directly. The main `$uix/eidos` barrel intentionally does **not** export `PickerShell`.
+
+## Why internal
+
+- Zero standalone semantics — no events, no state, no morfo contract beyond a single Provider stub.
+- All meaningful behaviour (Clear / Cancel / Close actions) flows through `pickerShellContext` registered by the host picker's provider in soma.
+- The contract surface that matters for apps is each individual picker's namespace, not the shell.
+
+## What lives where
+
+- **Morfo declaration:** `src/uix/morfo/internal/picker-shell.ts` — outside `morfo/components/` so the component audit (which walks public components) does not flag it for the public-artefact ruleset (demo, `texts.label`, public README requirements).
+- **Soma:** `src/uix/soma/components/picker-shell/` — the `PickerShellHandle` + context machinery the five pickers register against.
+- **Eidos parts (this directory):**
+  - `picker-shell.svelte` — Root
+  - `picker-shell-header.svelte` — Header zone
+  - `picker-shell-body.svelte` — Body zone (where the picker's payload lives)
+  - `picker-shell-footer.svelte` — Footer (action row)
+  - `picker-shell-clear.svelte` — Clear action
+  - `picker-shell-cancel.svelte` — Cancel action
+  - `picker-shell-close.svelte` — Close action
+
+## Adding a new composite picker
+
+1. Soma provider registers a `PickerShellHandle` via `pickerShellContext`.
+2. Eidos picker barrel re-exports the shell parts under its namespace:
+
+```ts
+import Footer from '../picker-shell/picker-shell-footer.svelte';
+import Clear from '../picker-shell/picker-shell-clear.svelte';
+// …
+MyPicker.Footer = Footer;
+MyPicker.Clear = Clear;
+```
+
+3. Apps use `<MyPicker.Footer>` / `<MyPicker.Clear>` like any other picker.
+
+## Closes
+
+audit-codex-full-1.md P1 #5 — "picker-shell existe pero no esta cerrado como pieza de sistema". Closed as INTERNAL primitive per the audit's own recommendation: *"Si es interna, no deberia salir como demo publica ni Morfo publico incompleto."*
