fix: initialize self.config in HermesCLI to fix AttributeError on slash commands

HermesCLI.__init__ never assigned self.config, causing an
AttributeError ('HermesCLI object has no attribute config')
whenever an unrecognized slash command fell through to the
quick_commands check (line 2832). This broke skill slash commands
like /x-thread-creation since the quick_commands lookup runs
before the skill command check.

Set self.config = CLI_CONFIG in __init__, matching the pattern
used by the gateway (run.py:199).
