Production builds previously still emitted info/warning/error entries
via os_log (content private-redacted, but entries, categories, and
timing metadata were visible, and message strings were constructed).
For a privacy-first app the right posture is silence: every SecureLogger
wrapper and both cores are now gated behind #if DEBUG, so release
builds construct no log strings and emit nothing. Debug builds are
unchanged (public formatting, level threshold via BITCHAT_LOG_LEVEL).

SecureLogger's public wrappers evaluated their message autoclosure before
the level check inside log(), so every filtered debug message across the
codebase still paid for string interpolation - hundreds of call sites on
the per-packet/per-event hot paths. The wrappers now guard the level
first, and debug() compiles out of release builds entirely. Regression
tests verify filtered messages are never constructed.
The two heaviest per-event debug logs (NostrRelayManager inbound events,
ChatNostrCoordinator geo events) are now sampled every 100th with a
running count, so debug-enabled dev builds stop emitting hundreds of
lines per minute in busy geohashes.
