Bygg NeuroSemantics AI: minimal mobilapp, en backend, IaC och CI/CD

Ersätter den tidigare webappen på denna branch med ett fokuserat monorepo:

- apps/mobile: Expo/React Native med tre vyer (Welcome, Chat, Paywall),
  Cognito hosted UI-inloggning (Apple/Google/e-post) och In-App
  Purchase/Play Billing via en gemensam purchases-modul.
- services/api: en enda Lambda-backend — OpenAI Responses API med
  Markdown-kunskapsbas som systeminstruktioner, free tier-gräns i
  PostgreSQL (HTTP 402 -> paywall) och kvittoverifiering bakom ett
  delat PaymentProvider-interface (Apple/Google, Stripe kan läggas
  till för webb senare).
- infra: AWS CDK-stack med API Gateway (JWT-authorizer), Lambda,
  Cognito, Aurora Serverless v2 och Secrets Manager.
- db/migrations: minimal datamodell (users + usage), inga
  konversationer sparas.
- GitHub Actions: CI (lint, typecheck, test) och deploy från main.

+# NLP fundamentals
+
+NLP (Neuro-Linguistic Programming) was developed in the 1970s by Richard
+Bandler and John Grinder by modeling effective therapists (Virginia Satir,
+Fritz Perls, Milton Erickson). It offers models for how people structure
+subjective experience.
+
+## Key presuppositions (working assumptions)
+
+- The map is not the territory.
+- People respond to their map of reality, not reality itself.
+- There is no failure, only feedback.
+- Every behavior has a positive intention in some context.
+- People already have the resources they need, or can create them.
+- The meaning of communication is the response it elicits.
+
+These are adopted as useful stances, not truth claims.
+
+## The Meta-Model
+
+A set of language patterns for recovering information deleted, distorted, or
+generalized in speech. Examples:
+
+- **Deletion**: "I'm afraid." → "Afraid of what, specifically?"
+- **Unspecified verb**: "He rejected me." → "How, specifically, did he reject you?"
+- **Universal quantifier**: "I always fail." → "Always? Every single time?"
+- **Modal operator**: "I can't speak up." → "What would happen if you did?"
+- **Nominalization**: "Our communication is bad." → "How are you communicating?"
+- **Mind reading**: "She thinks I'm useless." → "How do you know she thinks that?"
+
+The Meta-Model turns vague, limiting maps into specific, workable ones.
+
+## Representational systems and submodalities
+
+Experience is coded in sensory systems (visual, auditory, kinesthetic).
+Submodalities are the fine qualities of those codes — brightness, distance,
+size, volume, temperature. Shifting submodalities (e.g. shrinking and dimming
+a threatening inner image) often shifts the emotional response.
+
+## Anchoring
+
+Associating a state with a stimulus (a touch, word, or image) so the state can
+be re-accessed deliberately. Built by eliciting a strong state and applying
+the stimulus at its peak, then testing.
+
+## Well-formed outcomes
+
+Goals stated positively, within the person's control, sensory-specific,
+context-bound, and ecological (checked against the wider system of the
+person's life): "What do you want? How will you know you have it? What might
+it cost you?"
