gentle-pi v0.3.7

Fixes

• Respect neutral persona mode after reload by removing unconditional Spanish/Rioplatense voseo guidance from the shared orchestrator prompt.
• Add regression coverage for issue #21: neutral persona prompt includes neutral language guidance and excludes the old unconditional voseo instruction.
• Add artifact-language guardrails so persisted prompts/assets default to English.

Verification

• pnpm test
• pnpm publish --dry-run --no-git-checks
