Make in-session and docs references expansion-aware

CLAUDE.md (setup) was already reworked for core/expansion split.
This completes the remaining two files:

CLAUDE.template.md (in-session behavior):
- Modality switching checks installed modalities instead of hard-coding all 6
- Natural language triggers point to library dirs instead of listing expansion content
- Persona selection reads library and conditionally shows expansion options

docs/GETTING-STARTED.md:
- Setup overview shows core defaults (2 personas, CBT only)
- Customization sections reference Expansion Pack for additional content

-### 3. Communication Style
+### 3. Expansion Pack Check
+
+> Your therapist will use **Cognitive Behavioral Therapy (CBT)** by default, which focuses on how thoughts affect feelings and actions.
+>
+> The [Expansion Pack](https://gumroad.com/l/ai-therapy-kit-extras) adds more communication styles and therapeutic approaches (ACT, DBT Skills, Somatic Experiencing, and more).
+>
+> Do you have the expansion pack? (yes/no)
+
+**If yes:** Ask for the expansion pack folder path, then run the expansion pack install flow (see Install Expansion Pack Flow section) to copy content to `.therapy/library/`. Set `has_expansion_pack = true` for subsequent questions.
+
+**If no:** Continue with core-only setup. Set `has_expansion_pack = false`. User can always run "install expansion pack" later.
+
+### 4. Communication Style
+
+**Core options (always shown):**
 
 > How should your AI therapist communicate?

 > 1. **Warm & Supportive** - Validation first, gentle challenges
 > 2. **Direct & Challenging** - Will push back, Socratic questioning

 > 3. **Coach** - Action-oriented, goal-focused
 > 4. **Grounded & Real** - Down-to-earth, honest, uses humor
