feat: Configurable decisions archival thresholds in config.json

[diberry]

Problem

Archival thresholds are hardcoded constants in nap.ts (20KB, 30 days). Different projects have different write rates. Active projects need lower thresholds; stable projects can tolerate higher ones.

From

Flight + EECOM reviews of #20 (solution A5).

Proposed Schema

{
  "decisions": {
    "maxSizeKB": 15,
    "archiveAfterDays": 30,
    "archiveImplementedAfterDays": 7,
    "autoArchiveImplemented": true,
    "maxEntries": 75,
    "warnAtSizeKB": 10
  }
}

nap.ts reads from config.json, falls back to current hardcoded defaults.
