/reload-skills does not update Tab completion for newly installed skills

Description

After installing new skills and running /reload-skills, the command reports the new skills as added, but they do not appear in the Tab completion menu when typing / in the chat prompt. The only workaround is to restart the entire hermes session.

Root Cause

In cli.py, the module-level variable _skill_commands is assigned at startup:

# cli.py ~line 2149
_skill_commands = scan_skill_commands()

The Tab completion lambda captures this name:

# commands.py SlashCommandCompleter
skill_commands_provider=lambda: _skill_commands

When /reload-skills is invoked, it calls reload_skills() in agent/skill_commands.py, which internally does:

global _skill_commands
_skill_commands = {}
_skill_commands = scan_skill_commands()  # creates a NEW dict object

This updates the skill_commands module's own _skill_commands, but cli.py's module-level _skill_commands still points to the old dict object created at startup. The Tab completion lambda resolves _skill_commands from cli.py's scope, so it always reads the stale data.

Steps to Reproduce

1. Start hermes chat
2. Install a new skill (e.g. copy a skill directory to ~/.hermes/skills/)
3. Run /reload-skills — it prints "added N new skills"
4. Type / and press Tab — the new skill commands are missing
5. Restart hermes — now the new skills appear in Tab completion

Suggested Fix

In cli.py's _reload_skills() method, after calling reload_skills(), sync the module-level variable:

def _reload_skills(self, ...):
    from agent.skill_commands import reload_skills, get_skill_commands

    result = reload_skills()

    # Sync cli.py's module-level _skill_commands so the
    # Tab-completion lambda picks up the updated dict
    global _skill_commands
    _skill_commands = get_skill_commands()

    ...
