1ee4b3c2a0 fix(voice): stop poisoning design profiles with "[object Object]" instruct (#556)
Voice Studio "Save design as profile" passed buildDesignInstruct()'s RETURN
OBJECT ({instruct, unsupported, duplicates}) straight to FormData.append, which
string-coerced it to the literal "[object Object]". That got persisted into
voice_profiles.instruct and 400'd on first preview/use with "Unsupported instruct
items found in [object Object]" (#550 #545 #542 #537 #530 #525).

Fix the whole class + heal already-poisoned data (backward-compatible-data rule):
- CloneDesignTab.jsx:609 — pass `.instruct` (the string), not the builder object.
- useProfiles.js — append via new instructToFormValue() helper, which extracts
  `.instruct` if an object ever slips through again (defense-in-depth).
- omnivoice/_resolve_instruct — drop the "[object Object]" sentinel instead of
  raising, so any value that slips through (e.g. generation_history) degrades to
  neutral conditioning rather than a hard 400. A genuine unsupported token still
  raises (keeps the #114/#115 user feedback).
- migration 0006 — UPDATE voice_profiles SET instruct='' WHERE it's the sentinel,
  idempotent + table-guarded, to heal profiles saved on the buggy build.

Tests (fail-before/pass-after): frontend voiceInstruct (instructToFormValue never
yields "[object Object]"); backend _resolve_instruct tolerates the sentinel but
still rejects a real bad token; alembic 0006 heals a poisoned row, leaves a
healthy one untouched. Frontend 9 passed + typecheck clean; backend 5 passed.

"""Heal voice_profiles.instruct poisoned with the "[object Object]" sentinel.
Revision ID: 0006_strip_object_object_instruct
Revises: 0005_unified_profiles
Create Date: 2026-06-20 00:00:00.000000
A pre-fix Voice Studio build ("Save design as profile") passed the
``buildDesignInstruct()`` *object* straight to FormData, which string-coerced it
to the literal ``"[object Object]"`` and persisted that into
``voice_profiles.instruct`` (#550 #545 #542 #537 #530 #525). On first
preview/use that value fails the engine instruct validator with a 400. The
frontend + backend fixes stop any NEW poisoned rows; this migration heals the
ones already saved on the buggy build (the local-first backward-compat rule —
existing project data must keep working without manual migration).
