Debounce reconnect disconnect logging

[juliusmarminge]

Summary

• Prevent repeated disconnect warnings when multiple WebSocket subscriptions fail during the same reconnect window.
• Reset transport disconnect reporting after a subscription successfully receives a value, so future disconnects can be logged again.
• Avoid unhandled promise noise during replay recovery triggered by resubscribe and sequence-gap paths.
• Add coverage for the reconnect recovery path and the one-time disconnect log behavior.

Testing

• bun fmt
• bun lint
• bun typecheck
• bun run test

Note

Medium Risk
Touches WebSocket subscription retry/logging and orchestration replay recovery paths; mistakes could hide useful diagnostics or impact reconnection stability, but changes are small and covered by new tests.

Overview
Reduces noisy WebSocket disconnect warnings by ensuring WsTransport.subscribe logs transport disconnect only once per reconnect window, resetting once a subscription successfully receives a value.

Hardens environment orchestration recovery by scheduling replay recovery via a wrapper that swallows rejected promises (notably when triggered by onResubscribe or sequence gaps), preventing unhandled rejection noise.

Adds tests covering one-time disconnect logging when multiple subscriptions fail together and ensuring replay recovery failures during resubscribe don’t surface as unhandled rejections.

Note

Debounce disconnect logging and swallow replay recovery rejections in WebSocket transport

• WsTransport.subscribe now emits at most one 'WebSocket RPC subscription disconnected' warning per disconnect event when multiple subscriptions fail together; logging resets after the first successful message is received.
• Replay recovery rejections in createEnvironmentConnection are now swallowed via .catch(() => undefined), preventing unhandled promise rejections during sequence-gap or resubscribe-triggered recovery.

Approvability

Verdict: Approved

This PR makes two small, self-contained improvements: deduplicating WebSocket disconnect warning logs when multiple subscriptions fail together, and properly catching errors from replay recovery to prevent unhandled promise rejections. Both changes are low-risk logging/error-handling fixes with corresponding test coverage.
