v4.3

• Debug log gating — SystemLogger.debug() now skipped entirely in release builds, eliminating unnecessary logcat syscalls on every intercepted transaction.
• Supervisor backoff — Exponential restart delay (500ms → 30s cap) prevents CPU spin if the daemon crashes repeatedly. Resets automatically once stable.
• Process priority — Daemon runs at nice=10, yielding CPU to foreground apps on constrained devices.
• Map eviction — Rate limiter and file lock maps now evict stale entries instead of growing unbounded.
• CI pipeline — Single-trigger build→release pipeline with proper changelog extraction and correctly sized artifacts.
