/**
 * ToolTelemetryBridge — forwards local tool execution events to the HQ
 * publisher as `tool.started` and `tool.completed` envelopes, so the command
 * center can surface live tool activity (what's running, durations, success
 * rates) across every connected machine.
 *
 * Sources:
 *  - `tool.started` (EventBus) → `tool.started` envelope. Raw tool input is
 *    shaped via {@link summarizeHqToolArgs} according to the active HQ policy.
 *  - `tool.executed` (EventBus) → `tool.completed` envelope (carries the
 *    richer post-execution signal: duration, ok/error, output bytes).
 *
 * All payload fields are plain serializable data — no closures. The
 * `tool.started.input` raw args follow the publisher redaction policy before
 * publishing.
 *
