iOS: Add early resolution and conditional streaming for GET requests

[Copilot]

Fix Parallel Request Cancellation Issue

Problem:

When running multiple requests in parallel, they were getting cancelled during session recreation. This happened because recreateSession() was cancelling all active requests.

Checklist:

• Remove Request Cancellation:

  • Removed code that cancels active requests in recreateSession()
  • Active requests now continue on the old session until they complete
  • Keep old session alive for 30 seconds to allow requests to finish

• Test:

  • Verify parallel requests work without cancellation

Changes:

Before:

• recreateSession() cancelled all active requests when creating a new session
• Old session was kept alive for only 0.5 seconds
• Parallel requests would fail with cancellation errors

After:

• recreateSession() does NOT cancel active requests
• Active requests continue running on the old session
• Old session is kept alive for 30 seconds to allow requests to complete
• New requests use the new session with updated event monitors/interceptors
• Parallel requests can now run without interference

@farfromrefug I believe we can remove this log.
