feat: experimental NVIDIA power control via RM ioctl interface
Adds an experimental power-cap mode using the undocumented RM ioctl interface (based on panchovix's LACT PR #1205) to set power limits below the VBIOS minimum (down to 30 W). - hal/rm_power.py: RM ioctl power-cap read/write/reset + runtime probe - limits.py: power_cap_mode (nvml/ioctl) with support detection - config.py: persist power_cap_mode per GPU - profiles: record/apply power_cap_mode - server.py: POST /api/limits validates ioctl support (409 on failure) - cli.py: profile save falls back to persisted mode - client.py: power_cap_mode in Limits - frontend: toggle + warning with panchovix attribution (LACT #1205) - tests: test_rm_power.py (unit) + integration coverage - Makefile: add test_rm_power.py to make test Also includes automated linter reformatting (prettier, ruff, shellcheck, isort, markdownlint) that the linter would apply anyway.
