Telegram plugin: stale bun server.ts processes persist for days after CLI sessions are closed (idle ~120-130 MB RAM each)

Description

After enabling the Telegram channel integration in Claude Code CLI, each CLI session spawns a bun server.ts process for the Telegram plugin. When the CLI session is closed, these bun processes are not cleaned up and remain running as orphan/zombie processes indefinitely.

Unlike #43073 and #44670 (which describe 100% CPU zombies), these processes sit idle — no CPU usage, but consuming ~120–130 MB RSS each — and accumulate over multiple days.

Steps to Reproduce

1. Enable Telegram channel in Claude Code CLI (/telegram:configure)
2. Start a Claude Code CLI session (Telegram plugin bun server.ts starts)
3. Close/terminate the CLI session (exit or Ctrl+C)
4. Check for lingering bun processes: ps aux | grep "bun.*server.ts"
5. Repeat across multiple days / multiple sessions

Observed Behavior

After 6+ CLI sessions over several days (Thu → Fri → Mon → Wed → Thu → Fri), all 6 bun plugin processes were still running:

PID   RSS       STARTED   COMMAND
63416 125 MB    Thu11PM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)
19098 128 MB    Fri12AM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)
93509 132 MB    Thu06PM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)
54268 130 MB    Fri04PM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)
64038 122 MB    Tue03PM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)
58294 120 MB    Fri04PM   /Users/…/.bun/bin/bun server.ts  (cwd: telegram/0.0.4)

Total leaked RAM: ~757 MB across 6 orphaned processes.

Expected Behavior

When a Claude Code CLI session terminates, the Telegram plugin bun server.ts process spawned for that session should be killed/cleaned up.
