fix: YAML boolean handling for tool_progress config (#3300)

YAML 1.1 parses bare `off` as boolean False, which is falsy in
Python's `or` chain and silently falls through to the 'all' default.
Users setting `display.tool_progress: off` in config.yaml saw no
effect — tool progress stayed on.

Normalise False → 'off' before the or chain in both affected paths:
- gateway/run.py _run_agent() tool progress reader
- cli.py HermesCLI.__init__() tool_progress_mode

Reported by @gibbsoft in #2859. Closes #2859.
