v1.18.4

Bug Fix

• Neutral persona no longer leaks Argentine Spanish — Shared infrastructure assets (engram protocol, SDD orchestrator, Windsurf workflows) contained Rioplatense expressions (acordate, ¿Seguimos?, dale) that caused LLMs to infer voseo context and respond with "vos" even in neutral persona mode. All shared assets now use standard pan-Hispanic Spanish. Gentleman persona retains all Rioplatense expressions as designed.

Replacements

• acordate → removed (neutral recordar already present)
• ¿Seguimos? → ¿Continuamos? (all 7 editor-specific SDD orchestrators)
• dale / Dale → de acuerdo / De acuerdo (Windsurf workflow + orchestrator approval gates)

All changes are prompt/markdown only — zero Go code modifications.
