Feature Request: Support hot-reloading skills or add a /reload-skills command

[zaojingyoutu]

Problem

Currently, opencode scans and loads all skills only at startup. When a user creates or modifies a skill (e.g., adding a new skill to ~/.config/opencode/skills/ or .opencode/skills/), the changes are not recognized until opencode is completely restarted.

Suggested Solution

Implement one of the following:

1. Hot-reloading: Automatically detect changes in skill directories and reload them without restarting.
2. Manual reload command: Add a /reload-skills command that allows users to refresh the skill list during an active session.

Benefits

• Significantly improves the developer experience when creating or testing custom skills.
• Eliminates the need to restart the entire session just to load a new skill.
• Makes opencode more flexible and user-friendly for power users who frequently extend its capabilities.
