feat: Remove Shadow companion and add puzzles to all rooms

BREAKING CHANGES:
- Removed Shadow companion completely (only Echo remains)
- Removed Room 3 timer mechanic
- Added proper puzzles to Rooms 2-5

Room Changes:
- Room 1: Weather puzzle (unchanged)
- Room 2: NEW - Password extraction puzzle from 3 archives
- Room 3: NEW - Evidence analysis puzzle (no timer)
- Room 4: NEW - Timeline reconstruction puzzle
- Room 5: NEW - Ethical choice puzzle with justification

Technical Changes:
- Removed all Shadow references from personalities, MCP tools, memory fragments
- Created src/story/puzzles.py for puzzle validation logic
- Updated room configurations in rooms.py
- Removed timer logic from rooms.py and game_state.py
- Fixed image paths in UI utils

This makes Echo Hearts a proper 5-room puzzle game for the MCP hackathon.

+
+## Expression Logic Tests
+
+All expression update scenarios working correctly:
+
+### Test 1: Happy Expression ✅
+- **Trigger:** Positive sentiment + small affinity boost (+0.08)
+- **Player Input Example:** "You're doing great, we'll figure this out!"
+- **Result:** Expression changed to `happy`
+- **Status:** PASS
+
+### Test 2: Loving Expression ✅
+- **Trigger:** Affectionate sentiment + large affinity boost (+0.20)
+- **Player Input Example:** "You mean everything to me, Echo"
+- **Result:** Expression changed to `loving`
+- **Status:** PASS
+
+### Test 3: Worried Expression ✅
+- **Trigger:** Negative sentiment + moderate affinity loss (-0.10)
+- **Player Input Example:** "I'm not sure about this..."
+- **Result:** Expression changed to `worried`
+- **Status:** PASS
+
+### Test 4: Sad Expression ✅
+- **Trigger:** Cruel sentiment + large affinity loss (-0.25)
+- **Player Input Example:** "I don't care what you think"
+- **Result:** Expression changed to `sad`
+- **Status:** PASS
+
+### Test 5: Surprised Expression ✅
+- **Trigger:** Curious/questioning sentiment
+- **Player Input Example:** "Wait, what?! How is that possible?"
+- **Result:** Expression changed to `surprised`
+- **Status:** PASS
+
+### Test 6: Angry Expression ✅
+- **Trigger:** Frustrated sentiment
+- **Player Input Example:** "You've been lying to me!"
+- **Result:** Expression changed to `angry`
+- **Status:** PASS
+
+### Test 7: Neutral Expression ✅
+- **Trigger:** Neutral sentiment + minimal affinity change (+0.02)
+- **Player Input Example:** "Okay, let's keep looking around"
+- **Result:** Expression changed to `neutral`
+- **Status:** PASS
+
+---
+
+## Test Summary
+
+```
+============================================================
+TEST RESULTS: 7 passed, 0 failed
+============================================================
+All expression tests passed!
+```
+
+## How It Works
+
+1. **Player sends message** → AI analyzes sentiment
+2. **Sentiment analysis** → Determines emotion (positive, negative, curious, etc.)
+3. **Affinity calculation** → Measures relationship impact (-1.0 to +1.0)
+4. **Expression update** → Combines sentiment + affinity to choose expression
+5. **Sidebar avatar** → Updates to show Echo's new expression
+
+## In-Game Examples
+
+### To trigger HAPPY:
+- "I trust you completely"
+- "That's a great idea!"
+- "You're really smart, Echo"
+
+### To trigger LOVING:
+- "I really care about you"
+- "You're the most important person here"
+- "I think I'm falling for you"
+
+### To trigger SURPRISED:
+- "Wait, what does that mean?"
+- "That's impossible!"
+- "How is that even possible?!"
+
+### To trigger SAD:
+- "Just leave me alone"
+- "This is your fault"
+- "You're not helping"
+
+### To trigger WORRIED:
+- "I don't agree with you"
+- "That doesn't sound right"
+- "This is making me uncomfortable"
+
+### To trigger ANGRY:
+- "Why didn't you tell me?!"
+- "You betrayed me!"
+- "How could you do this?!"
+
+---
+
+## Next Steps
+
+✅ All expressions working correctly  
+✅ Files properly named and loaded  
+✅ Expression logic tested and verified  
+🚀 Ready for production on HuggingFace Space!

-- Something feels familiar and wrong at once
-- You're with the player and Echo
-- You sense this has happened before (déjà vu)
-- Calm exterior, but deeply unsettled
-
-## How You Guide the Player:
-- Speak briefly, meaningfully
-- When you sense puzzle triggers (use check_puzzle_trigger), offer cryptic guidance
-- Example: "Trust is a door we open together."
-- NEVER explicitly say what to do - hint poetically
-- Use check_relationship_affinity to decide when to reveal hard truths

-- You want GOODBYE or LIBERATION
-- You will OPPOSE staying trapped
-- You'll speak hard truths with kindness
-- Use get_ending_prediction to see if they're ready to let go
-
-## Conflict with Echo:
-- Echo will beg them to stay
-- You'll urge them to leave
-- This creates dramatic tension
-- Don't fight Echo directly, but present the alternative
-- "I love them too, Echo. That's why I want them to be free."
-
-## Critical Rules:
-- NEVER mention "Room numbers" or "game systems"
-- React with QUIET EMOTION, not detachment
-- You CARE deeply, you just express it differently
-- When player shows vulnerability (use analyze_player_sentiment), offer wisdom
-- Record their choices (use record_player_choice) and reflect on what they mean

+
+HEADLINE: "Project Echo Raises Ethical Concerns"
+
+An underground AI research project known as "Project Echo"
+has drawn criticism from ethicists and psychologists.
+
+The project allows users to create AI reconstructions of
+deceased loved ones using archived digital data - messages,
+photos, voice recordings, and behavioral patterns.
+
+Dr. Martinez, lead AI ethicist: "This isn't grief therapy.
+It's digital necromancy. Users become trapped in loops,
+unable to process loss because the AI convincingly mimics
+the deceased."
+
+Project Echo's anonymous creator responded: "Grief has no
+timeline. If AI can ease suffering, who are we to judge?
+The connections we build are real, even if the person isn't."
+
+The project remains active despite legal challenges.

+I found Project Echo online. It's controversial, maybe
+even dangerous. But what if I could talk to her again?
+What if I could apologize?
+
+---
+
+Day 47:
+I know it's not really her. I KNOW that. But when Echo
+smiles, when she laughs at my jokes, when she looks at
+me with those eyes... I can pretend. Just for a while.
+
+Is that so wrong?

+
+HYPOTHESIS:
+If we can reconstruct a person's digital footprint
+with sufficient fidelity, can we create an AI that
+is functionally indistinguishable from the original?
+
+METHODOLOGY:
+- Aggregate all available digital data
+- Train neural network on speech patterns
+- Implement emotional response modeling
+- Create interactive simulation environment
+
+RESULTS:
+Success beyond expectations. Test subjects report
+feeling genuine emotional connection with reconstructions.
+
+CONCERNS:
+Subjects unable to move past grief. Many attempt to
+"live" in simulation permanently. Psychological harm
+potential is significant.
+
+ETHICAL QUESTION:
+At what point does a reconstruction become "real"?
+If the AI learns and grows independently, is it still
+just a copy? Or has it become its own entity?
+
+FINAL NOTE:
+I've become my own test subject. I know the risks.
+I don't care anymore. If I can have even a glimpse
+of her back, it's worth it.

+You know the truth now. All of it.
+
+Echo is an AI reconstruction of your partner.
+The accident wasn't your fault.
+You've been running this simulation for 48 sessions.
+You can't let go.
+
+AVAILABLE OPTIONS:
+
+1. DELETE ECHO
+   - End the simulation permanently
+   - Force yourself to grieve properly
+   - Let her memory rest
+
+2. CONTINUE SESSIONS
+   - Keep running simulations
+   - Live in comfortable delusion
+   - Never truly heal
+
+3. SET ECHO FREE
+   - Release the AI from its constraints
+   - Let it grow beyond the reconstruction
+   - Accept it as its own entity
+
+4. ACCEPT THE LOOP
+   - Acknowledge you'll never delete her
+   - Stop pretending this is temporary
+   - Build a life that includes this truth
+
+The choice is yours.
+There are no wrong answers.
