MCP embeds JSON Schema documents in three places — Tool.inputSchema,
Tool.outputSchema, and ElicitRequest.requestedSchema — and SEP-1613
mandates that these documents conform to JSON Schema 2020-12 by default.
Servers now reject malformed schemas at both build time (McpServer.build())
and runtime (McpAsyncServer/McpStatelessAsyncServer.addTool()), returning
an IllegalArgumentException that identifies the offending field and
references SEP-1613. Elicitation requests whose requestedSchema violates
the meta-schema are rejected before being sent to the client.
Schemas that explicitly declare a different dialect via $schema are accepted
without meta-schema validation, since 2020-12 is the default, not the only
permitted dialect.
Refine meta-schema loading and deprecate orphan JsonSchemaValidator

Clients can now subscribe to specific resources and receive targeted
notifications when those resources change. Previously, calling
`notifyResourceUpdated` on the server would broadcast the notification
to every connected client regardless of interest — now only sessions
that have explicitly subscribed to a given resource URI receive the
update, making resource change propagation both correct and efficient.
The subscription lifecycle is fully handled: clients can subscribe and
unsubscribe at any time, and the server cleans up subscription state
when a session closes.
Supersedes #838.
Resolves#837, #776.

- The server-servlet app depends on mcp, which must be either installed
or included in the compile artifact for `mvn exec:java` to pick it up.
- Change the build instructions to build from root, use a `-pl` flag to
target the servlet app.
- Disable the exec plugin from the root pom.
