Detect CPU vendor by probing MSRs (Intel IA32_THERM_STATUS vs AMD
TCTL MSR C0010293). Support both Intel Tjmax-based and AMD direct
temperature reading. Log detected vendor per CPU at startup.
New local recipe coretempd reads IA32_THERM_STATUS MSR via the
new sys:msr scheme and exposes per-CPU temperatures via scheme:coretemp.
- Reads IA32_THERM_STATUS (0x19C) and IA32_TEMPERATURE_TARGET (0x1A2)
- Calculates Celsius from digital readout relative to TjMax
- Exposes /scheme/coretemp/ directory with per-CPU temperature files
- Added to redbear-mini.toml (inherited by redbear-full)
- Added 15_coretempd.service init file
