feat(release): enhance generate-release-notes with AI optimization and auto-update

Major improvements to release note generation system: **AI Model Optimization:** - Switch from Claude Sonnet 4.5 to Haiku 4.5 (67% cheaper, 50% faster) - Cost reduced from 1.0 to 0.33 Premium requests per generation - Generation time reduced from ~30s to ~15s - Quality maintained through improved prompt engineering **Improved Prompt Structure:** - Restructured prompt: instructions first, commit data last - Added explicit user-feature prioritization rules (sensors > config > developer tools) - Integrated file change statistics with each commit - Added file path guidance (custom_components/ = HIGH, scripts/ = LOW) - Added 3-step decision process with walkthrough example - Added explicit output constraints to prevent meta-commentary **Auto-Update Feature:** - Consolidated improve-release-notes functionality into generate-release-notes - Automatic detection of existing GitHub releases - Interactive prompt to update both title and body - Shows comparison: current title vs. new AI-generated title **File Statistics Integration:** - Added --stat --compact-summary to git log - Shows which files changed in each commit with line counts - Helps AI quantitatively assess change importance (100+ lines = significant) - Enables better prioritization of user-facing features **Testing Results:** - Generated title: "Price Volatility Analysis & Configuration" (user-focused!) - Successfully prioritizes user features over developer/CI changes - No more generic "New Features & Bug Fixes" titles - Thematic titles that capture main release highlights Impact: Release note generation is now faster, cheaper, and produces higher-quality user-focused titles. Single consolidated script handles both generation and updating existing releases.

+    PROMPT="You are tasked with generating professional release notes in GitHub-flavored Markdown from conventional commits.

-**Commits between ${FROM_TAG} and ${TO_TAG}:**
+**CRITICAL Format Requirements:**

-${COMMITS}
+1. **START with a single-line title using '# ' (H1 heading):**
+   - Analyze ALL commits and create a SHORT, descriptive title (max 5-7 words)

-**Format Requirements:**
-1. Parse conventional commit format: type(scope): description
-2. Group by type with emoji headings:
-   - 🎉 New Features (feat)
-   - 🐛 Bug Fixes (fix)
-   - 📚 Documentation (docs)
-   - <20> Dependencies (chore(deps))
-   - <20>🔧 Maintenance & Refactoring (refactor, chore)
-   - 🧪 Testing (test)
-3. **Smart grouping**: If multiple commits address the same logical change or feature:
+   **HOW TO CHOOSE THE TITLE:**
+   Step 1: Scan commit scopes and identify USER-FACING changes:
+     - feat(sensors): ✅ User feature (they see new sensors)
+     - feat(config_flow): ✅ User feature (they use config UI)
+     - feat(services): ✅ User feature (they call services)
+     - fix(translations): ✅ User fix (they see corrected text)
+     - feat(release): ❌ Developer tool (users don't see this)
+     - feat(ci): ❌ Infrastructure (users don't care)
+     - docs: ❌ Documentation (nice but not a feature)
+
+   Step 2: Among user-facing changes, prioritize by impact:
+     - New sensor types > Config improvements > Bug fixes > Translations
+     - Multiple related sensors = name the feature domain (e.g., \"Price Volatility Analysis\")
+     - Major config flow changes = \"Enhanced Configuration Experience\"
+
+   Step 3: Ignore developer/internal changes for title selection:
+     - Even if there are 10 release/ci/docs commits, they don't appear in title
+     - Title must reflect what USERS experience when they upgrade
+
+   **EXAMPLE DECISION PROCESS:**
+   Given these commits:
+     - feat(sensors): Add 4 volatility sensors with classification
+     - feat(release): Add automated release notes generation
+     - fix(translations): Fix hassfest validation errors
+     - docs: Restructure documentation
+
+   WRONG title: \"Release Automation & Documentation\" (developer-focused!)
+   RIGHT title: \"Price Volatility Analysis Features\" (user sees new sensors!)
+
+   **GOOD TITLES (user-focused):**
+   - \"# Advanced Price Analysis Features\" (new sensors = user feature)
+   - \"# Enhanced Configuration Experience\" (config flow = user-facing)
+   - \"# Improved Reliability & Performance\" (stability = user benefit)
+
+   **BAD TITLES (avoid these):**
+   - \"# Release Automation\" (developers don't read release notes!)
+   - \"# Developer Experience\" (not user-facing!)
+   - \"# New Features & Bug Fixes\" (boring, says nothing)
+
+   Keep it exciting but professional. Do NOT include version number.
+
+2. **After title, use '### ' (H3 headings) for sections:**
+   - ### 🎉 New Features (for feat commits)
+   - ### 🐛 Bug Fixes (for fix commits)
+   - ### 📚 Documentation (for docs commits)
+   - ### 📦 Dependencies (for chore(deps) commits)
+   - ### 🔧 Maintenance & Refactoring (for refactor/chore commits)
+   - ### 🧪 Testing (for test commits)
+
+3. **Smart grouping**: If multiple commits address the same logical change:
   - Combine them into one release note entry
   - Link all related commits: ([hash1](url1), [hash2](url2))
   - Use a descriptive summary that captures the overall change
+
 4. Extract 'Impact:' sections from commit bodies as user-friendly descriptions
+
 5. Format each item as: - **scope**: Description ([hash](https://github.com/${GITHUB_REPO}/commit/hash))
-6. Keep it concise, focus on user-visible changes
-7. **Exclude from release notes**:
+
+6. **Exclude from release notes (but still consider for context):**
   - Manifest.json version bumps: chore(release): bump version
-   - Development environment: feat/fix/chore(devcontainer), feat/fix/chore(vscode), feat/fix/chore(scripts), feat/fix/chore(dev-env)
-   - CI/CD infrastructure: feat/fix/chore/ci(ci), feat/fix/chore/ci(workflow), feat/fix/chore/ci(actions)
-8. **Include in release notes**:
+   - Development environment: feat/fix/chore(devcontainer), feat/fix/chore(vscode), feat/fix/chore(scripts)
+   - CI/CD infrastructure: feat/fix/chore/ci(ci), feat/fix/chore(workflow), feat/fix/chore(actions)
+   - IMPORTANT: These should NEVER influence the title choice, even if they're the majority!
+
+7. **Include in release notes (these CAN influence title):**
   - Dependency updates: chore(deps) - these ARE relevant for users
-   - Any user-facing changes regardless of scope
-9. Output ONLY the markdown, no explanations
+   - Any user-facing changes regardless of scope (sensors, config, services, binary_sensor, etc.)
+   - Bug fixes that users experience (translations, api, coordinator, etc.)

-**Examples of smart grouping:**
- Multiple commits fixing the same bug → One entry with all commits
- Commits adding a feature incrementally → One entry describing the complete feature
- Related refactoring commits → One entry summarizing the improvement
+8. **Understanding the file paths (use this to assess importance):**
+   - custom_components/tibber_prices/sensor.py = User-facing sensors (HIGH priority for title)
+   - custom_components/tibber_prices/binary_sensor.py = User-facing binary sensors (HIGH priority)
+   - custom_components/tibber_prices/config_flow.py = User-facing configuration (HIGH priority)
+   - custom_components/tibber_prices/services.py = User-facing services (HIGH priority)
+   - custom_components/tibber_prices/translations/*.json = User-facing translations (MEDIUM priority)
+   - scripts/ = Developer tools (LOW priority, exclude from title)
+   - .github/workflows/ = CI/CD automation (LOW priority, exclude from title)
+   - docs/ = Documentation (LOW priority, exclude from title)

-Generate the release notes now:"
+   **Key insight:** Large changes (100+ lines) in custom_components/tibber_prices/ are usually important user features!
+
+9. **Output structure example:**

+- Analysis of why you chose the title
