docs: fix stale README config defaults (wake 0.65, vad 700/15)

the lower [vad]/threshold bullets still said 0.6 / 800ms / max 10; sync to the real
defaults (wake_fuzzy_threshold 0.65, silence_ms 700, max_seconds 15). CLAUDE.md and
COMPACT.md (git-ignored) corrected on disk too (model small.en, same numbers).
