Insight-first monetization: trust-building free tier and pricing

Adjusts the paywall strategy from withholding toward insight-first:

- Free-tier instructions rewritten around the monetization philosophy:
  the goal is not to interrupt the conversation but to build trust. The
  free experience should leave the user feeling understood, respected
  and curious to continue, and should help the user reach a meaningful
  insight of their own. The rule is included verbatim: 'Never
  manufacture suspense. Create genuine curiosity by helping the user
  reach a meaningful insight, then offer a deeper level of analysis in
  Premium.'
- Premium transition sharpened: analysis_ready may only fire when the
  conversation has reached a meaningful point and the natural next step
  is a complete analysis, structured framework, personalised strategy,
  practical exercises or a step-by-step action plan — pausing
  immediately before that delivery, never mid-sentence or mid-
  explanation. Transition example updated to the new wording. Product
  feeling encoded: always 'I genuinely want to continue this
  conversation', never 'they stopped me just to make me pay'.
- Pricing: paywall now shows plan prices — localized prices fetched
  from the store via react-native-iap, falling back to $5.99/month and
  $49.99/year (~30% below monthly) until store config exists — plus
  the Premium includes list (unlimited conversations, unlimited
  analyses, personalised guidance, future feature updates).
- README: monetization philosophy, product feeling and pricing sections
  updated to match.

 ### The intelligent paywall
 
+**Monetization philosophy.** The goal is not to interrupt the conversation
+— the goal is to build trust. The free experience should make the user feel
+understood, respected, and curious to continue; only when the conversation
+has reached a meaningful point is Premium introduced. The rule given to the
+model, verbatim: _"Never manufacture suspense. Create genuine curiosity by
+helping the user reach a meaningful insight, then offer a deeper level of
+analysis in Premium."_

 The paywall is not a hardcoded message count. Free conversations run in
 _discovery mode_: the model asks relevant follow-up questions, names
-patterns, shows understanding, and builds toward an analysis — without
-delivering the full solution. When the problem is described, the information
-is sufficient, and a concrete action plan is ready, the model signals
-`analysis_ready`, writes a calm transition ("…I have a concrete strategy I
-would recommend. Continue with Premium to see the analysis and the
-recommended steps."), and the conversation pauses.
