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.

+# Neurosemantics
+
+Neurosemantics studies how humans create meaning — how neurology (body, brain,
+nervous system) and semantics (meaning, language, symbols) interact to produce
+our experienced reality. The field was developed primarily by L. Michael Hall,
+building on NLP, Alfred Korzybski's general semantics, and cognitive psychology.
+
+## Core ideas
+
+- **Meaning is constructed, not found.** Events have no inherent meaning; we
+  give them meaning through framing, language, and evaluation.
+- **The map is not the territory** (Korzybski). Our mental models of reality
+  are abstractions — useful, but never the thing itself. Suffering often comes
+  from confusing map with territory.
+- **Meaning becomes embodied.** The meanings we hold trigger neurological and
+  emotional states — "meaning becomes muscle". Changing meaning changes state.
+
+## The Meta-States model
+
+Hall's central contribution. Humans do not only experience primary states
+(fear, joy, curiosity); we reflexively bring states to bear _on_ other states:
+
+- Fear **of** fear → panic.
+- Acceptance **of** fear → calm courage.
+- Appreciation **of** learning → engagement.
+- Shame **about** anger → self-suppression.
+
+A meta-state is a state about a state. The higher-level state qualifies,
+tempers, or intensifies the lower one. Much of personal change work is about
+deliberately choosing which higher frames to apply to primary experiences.
+
+Practical use: ask "How do you feel _about_ feeling X?" to surface the
+meta-level structure, then invite a resourceful higher frame (acceptance,
+curiosity, self-compassion, humor).
+
+## Frames and frame games
+
+A frame is the context or reference point that determines meaning. Reframing
+changes the meaning by changing the frame:
+
+- **Context reframe**: "In what situation would this behavior be useful?"
+- **Meaning reframe**: "What else could this mean?"
+- **Outframing**: stepping to a higher logical level and setting a frame about
+  the whole game ("What does it say about you that you keep trying?").
+
+## The Meaning–Performance axis
+
+Hall describes human excellence as the interplay of two axes: the meanings we
+hold (beliefs, values, identities) and the performances we deliver (skills,
+actions). Peak performance occurs when rich, empowering meanings are closed
+into action. Coaching works both axes: enrich meaning, then bridge it to
+behavior ("How will you act on this today?").
