This PR implements the core logging infrastructure for the telemetry
system. It introduces the `ClearcutLogger` class, integrates it into the
server lifecycle events, and establishes the `ClearcutSender`
abstraction.
**Implementation Roadmap:**
This is the second in a series of PRs designed to implement a robust,
privacy-conscious telemetry system:
1. **CLI & Opt-out Mechanism
([Merged](https://github.com/ChromeDevTools/chrome-devtools-mcp/pull/757)):**
* Added `--usage-statistics` flag and transparency logging.
2. **Logger Scaffolding & Integration (This PR):**
* **`ClearcutLogger`**: Implemented the main logging entry point.
* **One-way Data Flow**: Integrated `logToolInvocation` and
`logServerStart` hooks into `main.ts` to capture events.
* **`ClearcutSender`**: Introduced a transport abstraction (currently a
dummy implementation) that will later handle HTTP requests, batching,
and retries.
* **Type Definitions**: Added TypeScript definitions for the telemetry
Protocol Buffer messages.
3. **Persistence Layer (Next):**
* Implement local state management to reliably track "First Time
Installation" and "Daily Active" metrics.
4. **Watchdog Process Architecture (Next):**
* Move `ClearcutSender` execution to a dedicated watchdog process to
ensure reliable event transmission even during abrupt server shutdowns.
5. **Transport, Batching & Retries (Next):**
* Finalize `ClearcutSender` with actual HTTP transport logic, including
event batching and exponential backoff retries.
