Fix Next.js tunnel route span filtering by extending dropMiddlewareTunnelRequests to also drop BaseServer.handleRequest spans that match the tunnel path, replacing a fragile transaction-name string comparison in the event processor with the early, attribute-based TRANSACTION_ATTR_SHOULD_DROP_TRANSACTION mechanism already used for middleware and fetch spans.

Fix Next.js tunnel route span filtering by extending dropMiddlewareTunnelRequests to also drop BaseServer.handleRequest spans that match the tunnel path, replacing a fragile transaction-name string comparison in the event processor with the early, attribute-based TRANSACTION_ATTR_SHOULD_DROP_TRANSACTION mechanism already used for middleware and fetch spans.

Fix Next.js tunnel route span filtering by extending dropMiddlewareTunnelRequests to also drop BaseServer.handleRequest spans that match the tunnel path, replacing a fragile transaction-name string comparison in the event processor with the early, attribute-based TRANSACTION_ATTR_SHOULD_DROP_TRANSACTION mechanism already used for middleware and fetch spans.
