feat: v2.1.0 - Selective saving, cleanup command, and SessionEnd hook

New features:
- /learn:analyze now uses signal detection to save only valuable lessons
  - Explicit commands: "ține minte", "remember", "memorează"
  - Stated preferences: "întotdeauna", "always", "never"
  - Repeated corrections (2+ times)
  - Historical references: "cum am discutat", "as we discussed"
- New /learn:cleanup command for memory hygiene
  - Scoring system for entry quality
  - Conservative mode with confirmation
  - Upgrade option to rewrite entries
- SessionEnd hook shows reminder on /exit, /clear, Ctrl+D
- Metadata tracking: source, confidence, reinforced, trigger

Changes:
- analyze.md: Added Pas 3.5 for signal detection
- cleanup.md: New command for reviewing/deleting entries
- hooks.json: Changed from Stop to SessionEnd
- scripts/session-end-reminder.sh: New reminder script
- Templates updated with metadata fields
- Documentation updated for v2.1.0

+A Claude Code plugin for capturing lessons learned during development sessions with **domain-based memory**, **selective saving**, and **memory hygiene**.
 
 ## Installation
 
@@ -12,17 +12,59 @@ claude plugin install learn@romfast-plugins
 
 | Command | Description |
 |---------|-------------|
-| `/learn:analyze` | Analyze conversation and propose lessons |
+| `/learn:analyze` | Analyze conversation and propose lessons (selective) |
 | `/learn:status` | Show memory statistics by domain |
 | `/learn:import <file>` | Import from another memory file |
 | `/learn:reflect` | Consolidate and clean up memory |
+| `/learn:cleanup` | Review and remove low-value entries |
 
 ## Features
 
-- **Domain-based memory**: Organized by backend, frontend, database, testing, etc.
-- **Selective loading**: Only relevant memories load via `paths` frontmatter
-- **Automatic domain detection**: Detects domain from files in conversation
-- **Auto-generated patterns**: Glob patterns suggested when creating new domains
+### Domain-based Memory
+- Organized by backend, frontend, database, testing, etc.
+- Selective loading via `paths` frontmatter
+- Automatic domain detection from files in conversation
+
+### Selective Saving (v2.1.0)
+
+The plugin now uses intelligent signal detection to save only valuable lessons:
+
+**What Gets Saved (High Priority):**
+- Explicit commands: "ține minte", "remember this", "memorează"
+- Stated preferences: "întotdeauna fă X", "always do Y"
+- Repeated corrections: Same issue corrected 2+ times
+- Historical references: "cum am discutat", "as we discussed"
+
+**What Gets Filtered Out:**
+- One-time typo fixes
+- Single-file specific bugs
+- Import path corrections
+- Hardcoded value adjustments
+
+### Memory Hygiene (v2.1.0)
+
+Each entry now tracks metadata for cleanup:
+
+| Field | Description |
+|-------|-------------|
+| `source` | How it was captured: explicit, inferred, or repeated |
+| `confidence` | Signal strength: high, medium, or low |
+| `reinforced` | Times used in subsequent sessions |
+| `trigger` | Original phrase that triggered saving |
+
+Run `/learn:cleanup` periodically to review and remove low-value entries.
+
+### SessionEnd Hook
+
+When you exit a session (`/exit`, `/clear`, `Ctrl+D`), the plugin shows a reminder:
+
+```
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+💡 Tip: Rulează /learn:analyze pentru a captura lecțiile din sesiune
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+```
+
+**Note**: Requires Claude Code 2.0.50+ for `/clear` to trigger the hook.

+## Memory Format
+
+Entries are saved with metadata:
+
+```markdown
+### API Response Format Standard
+**Discovered**: 2025-01-06 (feature: user-api)
+**Source**: explicit | **Confidence**: high | **Reinforced**: 3
+**Trigger**: "ține minte să folosești acest format"
+**Description**: All API responses must use {data, error, meta} structure
+
+**Example** (`src/api/users.ts:45`):
+```typescript
+return { data: users, error: null, meta: { count: 10 } }
+```
+
+**Tags**: api, response, format
+```
+
 ## Development
 
 ```bash
+# Test the plugin
 claude --plugin-dir ./plugins/learn
+
+# Verify commands
+/learn:status
+/learn:analyze
+/learn:cleanup --dry-run
 ```
