Celia Chen b87327f4e5 Add rustls fallback for local MCP HTTP requests (#38436) ...

## Why

Local MCP requests can fail when the platform TLS backend cannot negotiate a
protocol version with an HTTPS endpoint.

## What changed

- Retry replayable local MCP requests once with rustls after a recognized TLS
  protocol-version negotiation failure. Keep certificate, timeout, and unrelated
  connection failures on the existing error path.
- Remember successful fallback per HTTPS origin and outbound route, while keeping
  the platform TLS backend as the default for other destinations.
- Share the fallback-enabled client across local MCP resolution, CLI login, and
  OAuth discovery while preserving remote environment HTTP clients.

## Testing

Added coverage for platform-specific error detection, request replay, cached
fallback reuse and isolation, non-replayable requests, redirects, and remote MCP
client selection.
