[v1.2] Add reconnection example to examples/python.md (and parity for examples/node.md)

[MaxMansfield]

Context

examples/python.md has no reconnection example. The closest reference is zoom/rtms-samples/rtms_api/reconnection_and_chaos_mode_js which uses raw WebSockets. A Python equivalent using the SDK's callbacks (on_media_connection_interrupted) doesn't exist in our docs.

Anyone deploying RTMS to a real production environment hits all three reconnection scenarios from Zoom's docs (https://developers.zoom.us/docs/rtms/meetings/work-with-streams/#failover-and-reconnection). Without a blessed example, every customer reinvents the pattern and most get it subtly wrong.

A working reference implementation already exists in the rtms-on-AWS Terraform template's worker/main.py (built 2026-05-20 by @MaxMansfield).

What to ship

Add a "Reconnection" section to examples/python.md (between the existing media callbacks and asyncio sections). Cover all three Zoom scenarios using SDK callbacks (not raw WS):

Scenario	Trigger	Handler
1. RTMS server failure	meeting.rtms_started arrives for an existing rtms_stream_id with new server_urls	leave old client, join with new payload
2. Signal connection down	meeting.rtms_interrupted webhook	tear down and rejoin with the webhook's fresh credentials
3. Media connection down	on_media_connection_interrupted callback	re-issue client.join(stored_payload) with exponential backoff

Code sample: take the working pattern from terraform-template/worker/main.py (_schedule_media_reconnect, handle_interrupted, start_meeting's server-failure detection). Exponential backoff: 3s × 2^n capped at 30s, max 5 attempts.

Acceptance criteria

• New "Reconnection" section in examples/python.md
• All three Zoom scenarios covered with runnable code
• Reference to the official Zoom failover docs URL
• State machine for tracking stored payloads per stream_id documented

Cross-language parity

• Add the equivalent "Reconnection" section to examples/node.md with the JS equivalent of the same patterns
• Same scenario table and same handler shapes
• PR description includes "Cross-language parity check" section

Source

Tracked in vault: Projects/RTMS SDK v1.2.md → DEVS-X4. Reference implementation: terraform-template/worker/main.py from the 2026-05-20 AWS deploy work.
