fix: update improve-skills command for Factory Droid CLI

**Critical Fix**: Factory Droid CLI version was looking at wrong directory

## Problem
The /improve-skills command in Factory Droid CLI was hardcoded to look for
`.claude/skills/` directory, which doesn't exist in Factory installations.

When users ran `/improve-skills` in Factory Droid CLI:
- ❌ Command failed to find skills
- ❌ Checked wrong directory (.claude/skills/ instead of .factory/skills/)
- ❌ Referenced "Claude Code" throughout
- ❌ User couldn't improve their skills

## Solution
Updated Factory Droid CLI version to:
- ✅ Check `.factory/skills/` directory
- ✅ Use platform-neutral language
- ✅ Update all user-facing messages
- ✅ Keep Claude Code version unchanged

## Changes
`droid_cli/default/commands/improve-skills.md`:
- Changed all `.claude/skills/` → `.factory/skills/`
- Changed "Claude Code Skills" → "Skills"
- Updated confirmation message
- Updated final recommendations message

`claude/default/commands/improve-skills.md`:
- No changes (already correct for Claude Code)

## Impact
✅ Factory Droid CLI users can now use /improve-skills
✅ Command works correctly in both platforms
✅ Each platform checks its own skills directory

## Testing
Run in Factory Droid CLI:
```
> /improve-skills
AI: Checks .factory/skills/ ✅
AI: Improves skill descriptions ✅
```

Run in Claude Code:
```
> /improve-skills
AI: Checks .claude/skills/ ✅
AI: Improves skill descriptions ✅
```

 RECOMMENDATION 👉 Review and revise them further using these tips:
 
 - Make Skills as descriptive as possible
-- Use their 'description' frontmatter to tell Claude Code when it should proactively use this skill.
+- Use their 'description' frontmatter to describe when this skill should proactively be used.
 - Include all relevant instructions, details and directives within the content of the Skill.
 - You can link to other files (like your Droidz standards files) using markdown links.
-- You can consolidate multiple similar skills into single skills where it makes sense for Claude to find and use them together.
