Fixes #15

Changes:

Add explicit config words: BOREN=NSLEEP, MCLRE=OFF, FCMEN=OFF, IESO=OFF
Disable comparator before sleep (was never shut down)
Add defensive stop_fvr_tmp_adc() before sleep

Power-down budget (3.0V typical):

Base IPD: 30nA
WDT: 500nA
Total: ~530nA (matches product brief spec)

BOREN=NSLEEP saves 300nA during sleep while keeping BOR active during awake operation.

fix: shut down peripherals before sleep, add config words 82ded88d12

Add explicit config words: BOREN=NSLEEP (saves 300nA in sleep), MCLRE=OFF
(frees RA3), FCMEN=OFF, IESO=OFF. Disable comparator before sleep (Issue #15)
as it was never shut down. Also add stop_fvr_tmp_adc() before sleep as a
defensive measure to ensure FVR/ADC are off.

Power-down budget at 3.0V typical:
- Base IPD: 30nA
- WDT: 500nA
- Total: ~530nA (matches product brief RF Sleep spec)
