Command "/skills reload" not always work

### Describe the bug

I create a new Skill by just describing the Skill to the Agent, it creates the Skill, write it in the global skill folder. When I use the command "`/skills reload`", it says there is 1 more Skill than before, however if I use "`/skills list`" the Skill is not listed.

### Affected version

1.0.59

### Steps to reproduce the behavior

For example, let's say I have 2 Skills (Skill A and Skill B),
1. I run "/skills reload" it says 2 Skills,
2. I add Skill C,
3. execute "/skills reload" and it says there are 3 Skills, but
4. if I run "`/skills list`", it only shows 2 Skills.

### Expected behavior

In Step 4. if I run "`/skills list`", it should display all 3 Skills.

### Additional context

**Workaround**: I have to exit Copilot, start it again and the new Skill now appears with "`/skills list`".

Start at the CLI entry points for `/skills reload` and `/skills list`, then reproduce the sequence with two existing Skills and a newly created global Skill. Trace why reload reports the new count while list still omits the Skill; done means `/skills list` displays all Skills immediately after reload without restarting Copilot.
