Add lightweight Hono + Bun servers for server-only compute endpoints.
CRUD is handled by mana-sync, these handle AI + file upload only.
Traces: AI guide generation, location sync (Port 3026)
Planta: Photo upload (S3), AI plant analysis (Port 3022)
NutriPhi: AI meal analysis (photo+text), recommendations (Port 3023)
Each uses @manacore/shared-hono for auth/health/errors. ~100-200 LOC.
