Centralized config with env-override helpers

Define all runtime thresholds (timeouts, retry counts, size limits, score thresholds) in a single config module. Expose tiny typed helpers — envInt(name, default), envFloat(name, default), envStr(name, default) — that safely parse env vars and fall back.

Why

Prevents "magic numbers" from spreading across modules and gives ops a single, grep-friendly surface for tuning. Helpers guard against NaN from malformed env input.

Mechanism

const envInt = (n, d) => {
  const v = parseInt(process.env[n], 10);
  return Number.isFinite(v) ? v : d;
};

module.exports = {
  VALIDATION_TIMEOUT_MS: envInt('VALIDATION_TIMEOUT_MS', 180_000),
  HEARTBEAT_MS: envInt('HEARTBEAT_MS', 360_000),
  SOLIDIFY_RETRIES: envInt('SOLIDIFY_RETRIES', 2),
  BROADCAST_SCORE_MIN: envFloat('BROADCAST_SCORE_MIN', 0.7),
  // ...
};

When to reuse

Any daemon or long-running CLI with dozens of tunable knobs. Prefer this over dotenv spread through the codebase.
