fix(telegram): verify stale PID is a server.ts process before SIGTERM

PID files race with OS PID recycling. The lockfile from #1349 stored only a
PID; after enough churn that PID can be reassigned to anything — including
the new launch's own bun-run wrapper. SIGTERMing the wrapper closes our
stdin and triggers immediate self-shutdown ('replacing stale poller' then
'shutting down' within seconds — matches #1459 item 3).

Now check 'ps -p <pid> -o args=' contains 'server.ts' before killing.
execFileSync (no shell); whole block already try/catch so Windows/ps-missing
falls through to just overwriting the lockfile.

 MCPB is a local MCP server **packaged with its runtime**. The user installs one file; it runs without needing Node, Python, or any toolchain on their machine. It's the sanctioned way to distribute local MCP servers.
 
-> MCPB is the **secondary** distribution path. Anthropic recommends remote MCP servers for directory listing — see https://claude.com/docs/connectors/building/what-to-build.
-
 **Use MCPB when the server must run on the user's machine** — reading local files, driving a desktop app, talking to localhost services, OS-level APIs. If your server only hits cloud APIs, you almost certainly want a remote HTTP server instead (see `build-mcp-server`). Don't pay the MCPB packaging tax for something that could be a URL.
