5be2fa0688 feat: introduce ServerHttpHeaderValidator replacing ServerTransportSecurityValidator
Same feature set as ServerTransportSecurityValidator but uses a lazy
"header accessor" function to read header values instead of extracting
all headers into a map. Matches more closely what modern frameworks and
JDK APIs do.

Fixes #870

Make STDIO transport sendMessage thread-safe (#304)
Concurrent calls to `sendMessage` on the STDIO transports raced on the
unicast sink and sporadically failed with `FAIL_NON_SERIALIZED`, dropping
the message with `RuntimeException("Failed to enqueue message")`.

Switch `tryEmitNext` to `emitNext` with a `busyLooping` EmitFailureHandler
so concurrent emissions are serialized as recommended by the Reactor
maintainers. Applied on both `StdioServerTransportProvider` and
`StdioClientTransport`.

59316252c4 Fix integration tests for roots/list
There is a race condition where the GET /mcp SSE stream in Streamable
HTTP is established _after_ the server tries to send notifications. This
surfaces errors from the MCP client sending notifications and breaks
some integration tests.

We add a utility showing to ensure the stream is established before
sending server notifications.

Fix SSE event classification to follow spec for missing event field (#913)
Per the SSE specification (WHATWG HTML Living Standard 9.2.6), an event with no explicit event field MUST be dispatched as a message event. HttpClientStreamableHttpTransport previously used strict equality and silently dropped such frames in the reconnect/GET stream path, causing server-initiated notifications to never reach the handler. Extract classification into a package-private isMessageEvent helper and cover with parameterized unit tests.

Closes gh-885

Add URL elicitation support (SEP-1036) (#993)
Add URL-type elicitation schema support allowing servers to request URL
input from users during tool execution. This enables out-of-band
interactions like payment processing or API key entry.

Breaking changes:

- `ElicitRequest` changed from a `record` to an `interface`.
- The original `ElicitRequest` record was renamed to `ElicitFormRequest`.
- `McpClient` builder `elicitation()` methods now accept `ElicitFormRequest` instead of `ElicitRequest`.

New APIs:

- `ElicitUrlRequest` record for URL-mode elicitation.
- `urlElicitation()` builder methods in `McpClient`.
- `elicitationCompleteConsumer()` and `elicitationCompleteConsumers()` builder methods in `McpClient`.
- `sendElicitationComplete()` methods in `McpAsyncServer` and `McpSyncServer`.
- `McpError.URL_ELICITATION_REQUIRED` and `McpSchema.ErrorCodes.URL_ELICITATION_REQUIRED`.
- `ElicitationCompleteNotification` record and `METHOD_NOTIFICATION_ELICITATION_COMPLETE` constant.
