fix(telegram): suppress verbose-off tool trace bubbles

[artemgetmann]

Review Fast Path

• User path fixed: Telegram/Jarvis verbose-off chats no longer show internal 🔧 read, 🔧 memory_search, 🔧 process, or 🔧 exec tool/status trace bubbles while commands run.
• Proof: focused unit suite passed, full build passed, isolated tester runtime owned this worktree, and live tester bot showed before/after: pre-fix 49758 leaked 🔧 read; post-fix prompt 49764 produced only TOOL_TRACE_SPAM_CHECK_DONE_2 with no 🔧 bubbles.
• Shared-state footgun removed: tester proof used isolated runtime runtime_worktree=/Users/user/Programming_Projects/openclaw/.worktrees/telegram-tool-trace-spam-20260518, bot @Artem_jarvis_exec_bot, token claim count 1; main Jarvis bot was not touched during validation.
• Still hurts: this does not redesign progress/final splitting from PR fix(telegram): split progress from final replies #732; it only closes the verbose-off internal tool-label leak.

Why This Matters

Normal Jarvis chats should not expose implementation/tool internals. PR #748 only blocked some exec/cron paths, so other tool labels like read, memory_search, and process could still become Telegram-visible text.

Scope Boundary

• Suppresses wrench-prefixed internal tool trace text in Telegram when verbose is off.
• Preserves verbose-on tool traces.
• Preserves media-bearing tool payload delivery by stripping only the trace caption.
• Does not suppress the watchdog “Still working...” ping.
• Does not change main runtime ownership or shared LaunchAgent behavior.

Verification

• pnpm exec vitest run extensions/telegram/src/bot-message-dispatch.test.ts --pool=forks --maxWorkers=1 passed: 1 file / 76 tests.
• pnpm build passed.
• git diff --check passed.
• Isolated live proof:
  • runtime_ownership=ok
  • runtime_pid=23040
  • runtime_port=24104
  • current_lane_bot=@Artem_jarvis_exec_bot
  • baseline smoke passed before feature test
  • pre-final fix live failure: message 49758 contained 🔧 read\n\nTOOL_TRACE_SPAM_CHECK_DONE
  • post-final fix live pass: messages after prompt 49764 contained only TOOL_TRACE_SPAM_CHECK_DONE_2, no visible 🔧 bubbles
