v2.1: Unify skills and slash commands pattern (#5)

* v2.1: Unify skills and slash commands pattern

Following the new Claude Code standard where skills and slash commands
are merged into a single unified pattern:

- Convert commands to skills: /daily-workflow, /weekly-review, /push, /onboard
- Each skill has SKILL.md with frontmatter (name, description, allowed-tools)
- Skills can be invoked with /skill-name OR auto-discovered by Claude
- Remove deprecated .claude/commands/ directory
- Update all documentation to reference new unified pattern
- Update agents to reference skills instead of commands
- Update CLAUDE.md with unified skills table

This aligns with Claude Code 2.1+ where skills and slash commands
share the same features and invocation patterns.

* Simplify skill names: daily-workflow → daily, weekly-review → weekly

Rename verbose skill folders and names to shorter, cleaner invocations:
- daily-workflow/ → daily/ (invoked with /daily)
- weekly-review/ → weekly/ (invoked with /weekly)

Update all references across documentation, agents, and skill files
to use consistent short command names.

+# Git Push Skill
+
+Automates Git workflow to save your notes with meaningful commit messages and push to remote repository.
+
+## Usage
+
+Invoke with `/push` or ask Claude to save/commit your changes.
+
+### Basic Usage
+```
+/push
+```
+
+### With Custom Message
+```
+/push "Completed project planning"
+```
+
+## What This Skill Does
+
+1. **Stages All Changes**
+   - Adds all modified files
+   - Includes new files
+   - Removes deleted files
+
+2. **Creates Smart Commit Message**
+   - Uses provided message, or
+   - Auto-generates from changes
+   - Includes date/time stamp
+   - Summarizes key modifications
+
+3. **Syncs with Remote**
+   - Pulls latest changes (if enabled)
+   - Pushes to remote repository
+   - Handles merge conflicts gracefully
+
+## Commit Message Format
+
+### Automatic Messages
+Based on your changes:
+```
+Daily note for 2024-01-15 + 3 project updates
+- Added: Daily Notes/2024-01-15.md
+- Modified: Projects/Learning Spanish/notes.md
+- Modified: Goals/2. Monthly Goals.md
+```
+
+### With Timestamp
+```
+[2024-01-15 09:30] Completed weekly review
+```
+
+## Workflow Integration
+
+### Morning Routine
+```
+/daily          # Create daily note
+# ... work on notes ...
+/push "Morning planning complete"
+```
+
+### End of Day
+```
+# Complete daily reflection
+/push           # Auto-message with summary
+```
+
+### After Weekly Review
+```
+/weekly         # Run weekly review
+/push "Weekly review - Week 3"
+```
+
+## Git Operations
+
+### Standard Flow
+1. `git add .` - Stage all changes
+2. `git commit -m "message"` - Create commit
+3. `git pull --rebase origin main` - Get remote changes
+4. `git push origin main` - Push to remote
+
+### Safety Checks
+- Verify Git repository exists
+- Check for uncommitted changes
+- Ensure remote is configured
+- Validate branch exists
+
+## Conflict Handling
+
+If conflicts occur:
+1. Auto-resolve attempts (favor local for notes)
+2. If manual resolution needed, guide through process
+3. Never force push without explicit request
+
+## Security Considerations
+
+### Never Commit
+- Passwords or credentials
+- API keys
+- Personal identification
+- Financial information
+
+### Use .gitignore for
+```
+private/
+credentials.md
+.env
+.obsidian/workspace*
+.obsidian/cache
+.trash/
+.DS_Store
+```
+
+## Troubleshooting
+
+### Push Rejected?
+Pull first, then push again:
+```bash
+git pull --rebase origin main
+git push origin main
+```
+
+### Not a Git Repository?
+```bash
+git init
+git remote add origin [URL]
+```
+
+### Large Files Issue?
+Consider Git LFS for images/attachments.
+
+## Integration
+
+Works with:
+- `/daily` - Commit after creating daily note
+- `/weekly` - Commit after weekly review
+- `/onboard` - No git needed for context loading
+- Auto-commit hook for automatic saves
