fix(gateway): roll over telegram tool progress bubbles

[LeonSGP43]

What does this PR do?

Fixes Telegram tool-progress rollover so long-running gateway turns stop editing a full progress bubble and continue from a fresh one before hitting Telegram's single-message limit. The gateway now also honors an adapter's returned replacement message_id after successful edits so follow-up updates keep targeting the newest visible progress message.

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)
• ✨ New feature (non-breaking change that adds functionality)
• 🔒 Security fix
• 📝 Documentation update
• ✅ Tests (adding or improving test coverage)
• ♻️ Refactor (no behavior change)
• 🎯 New skill (bundled or hub)

Changes Made

• Added platform-aware message-limit helpers in gateway/run.py for progress-bubble sizing.
• Rolled over tool-progress bubbles before an edit would exceed the adapter message limit instead of replaying the full historical transcript into the same Telegram bubble.
• Updated the progress loop to adopt replacement message_id values returned by edit_message().
• Added a regression test in tests/gateway/test_run_progress_topics.py covering Telegram rollover behavior with a constrained message limit.

How to Test

1. Run python3 -m pytest -o addopts='' tests/gateway/test_run_progress_topics.py.
2. Confirm test_run_agent_telegram_progress_rolls_over_before_edit_overflow passes.
3. In a Telegram gateway session with display.tool_progress: all, run a tool-heavy turn and verify progress opens a second bubble before the first one overflows.

Duplicate of #26208 — same Telegram tool progress bubble rollover fix for #26207.

Closing in favor of #26208 — both fix the same bug (#26207, Telegram tool-progress bubbles exceeding the platform message limit). #26208 was submitted first, similar approach (rollover before limit), and similar diff scope. Functionally equivalent. Thanks for the parallel work.
