Subject: [PATCH] feat(08-03): create useToastStore Pinia stub with locked
 show() contract

- Defines show(message, type='success', duration=4000) as silent no-op
- Positional parameters only per UI-SPEC.md contract
- Phase 10 (UX-10) must implement rendering without modifying call sites

+ * Phase 7.1 STUB — Phase 10 (UX-10) fills in the full implementation.

+ * The signature `show(message, type, duration)` is locked and Phase 10 must
+ * honor it without modifying Phase 8 call sites.
+ *
+ * Default values match UI-SPEC.md:
+ *   type     = 'success'  (NOT 'info')
+ *   duration = 4000
