feat: add new skills for coding standards, continuous learning, detail layout, form layout, project guidelines, security review, and verification loop

- Introduced coding standards for TypeScript and React in SKILL.md.
- Added continuous learning skill with configuration and evaluation scripts.
- Created detail layout guidelines for read-only pages.
- Established form layout rules for data-entry forms.
- Documented project guidelines for the frontend monorepo.
- Implemented security review checklist for frontend/Electron applications.
- Developed a verification loop skill for comprehensive session checks.

This commit enhances the skill set available for developers, ensuring adherence to best practices and improving code quality.

+description: Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.

+
+# Strategic Compact Skill
+
+Suggests manual `/compact` at strategic points in your workflow rather than relying on arbitrary auto-compaction.
+
+## Why Strategic Compaction?
+
+Auto-compaction triggers at arbitrary points:
+- Often mid-task, losing important context
+- No awareness of logical task boundaries
+- Can interrupt complex multi-step operations
+
+Strategic compaction at logical boundaries:
+- **After exploration, before execution** - Compact research context, keep implementation plan
+- **After completing a milestone** - Fresh start for next phase
+- **Before major context shifts** - Clear exploration context before different task
+
+## How It Works
+
+The `suggest-compact.sh` script runs on PreToolUse (Edit/Write) and:
+
+1. **Tracks tool calls** - Counts tool invocations in session
+2. **Threshold detection** - Suggests at configurable threshold (default: 50 calls)
+3. **Periodic reminders** - Reminds every 25 calls after threshold
+
+## Hook Setup
+
+Already wired in `.cursor/hooks.json` as an `afterFileEdit` command:
+
+```json
+{
+  "version": 1,
+  "hooks": {
+    "afterFileEdit": [
+      {
+        "command": "node .cursor/scripts/hooks/suggest-compact.js"
+      }
+    ]
+  }
+}
+```
+
+## Configuration
+
+Environment variables:
+- `COMPACT_THRESHOLD` - Tool calls before first suggestion (default: 50)
+
+## Best Practices
+
+1. **Compact after planning** - Once plan is finalized, compact to start fresh
+2. **Compact after debugging** - Clear error-resolution context before continuing
+3. **Don't compact mid-implementation** - Preserve context for related changes
+4. **Read the suggestion** - The hook tells you *when*, you decide *if*
