…te esc/bold/code/italic, add backoff Fixes #352: - Converted standalone tgApi() to private instance method (removes global rateLimitUntil) - Removed duplicate HTML escaping functions (esc, bold, code, italic) — now using telegram-style.ts imports directly - Added exponential backoff to pollLoop errors (1s → 2s → 4s → 8s → 16s → max 30s) - Added pollBackoffMs instance variable for graceful error recovery This resolves test isolation issues and removes ~60 lines of dead duplicated code.

Summary
Fixes #352 — TelegramChannel monolith refactor.
Changes
Converted tgApi() to private instance method — removed global rateLimitUntil variable, now instance state. Fixes multi-instance and test isolation issues.
Removed duplicate HTML escaping functions — esc(), bold(), code(), italic() were defined identically in both telegram.ts and telegram-style.ts. Now using the telegram-style.ts imports directly.
Added exponential backoff to pollLoop — errors now back off exponentially (1s → 2s → 4s → 8s → 16s → max 30s) instead of fixed 5s sleep. Resets on successful response.
Added pollBackoffMs instance variable — tracks current backoff state for graceful error recovery.
