Implement the last version of the mcp schema and complete restructuring
of the mcp schema implementation from a monolithic `types.kt` file into
separate files.
- #158
- #185
- #353
- #298
- #248
## Motivation and Context
The previous implementation of the mcp schema was outdated and contained
several issues. In addition, it stored all mcp types in a single large
file, which made maintenance and further development more difficult
## How Has This Been Tested?
All tests passed
## Breaking Changes
Yes. The new types are now located in a separate package. Additionally,
many types have new parameters and modified constructors

Improves server versatility and developer experience by enabling STDIO
and refining setup.
## How Has This Been Tested?

# #302 Update samples build workflow
- Introduce workflow to build samples independently from the main
project
- Keep building samples against the current snapshot version of the SDK.
Update composite build configuration.
- Temporarily disable "samples/kotlin-mcp-server": the multiplatform
project is broken. **It doesn't compile for me even on the main
branch**. Not working with [MCP
Instepcor](https://modelcontextprotocol.io/docs/tools/inspector),
because CORS is not configured. Deserves a separate PR to fix.
## Motivation and Context
Samples should be independently buildable

Don't bind the sample server to `0.0.0.0` by default as that exposes the
server to anyone else on the local network.
If anyone were to use these samples as staring points to build larger
services, those servers would thus expose developers to attack
immediately upon launch.
I'd prefer if we avoided that 😆
## Motivation and Context
🔒 Security
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were

Introduce a `ServerSession` to manage multiple connections to the mcp
server. `Protocall` logic of the `Server` was moved to `ServerSession`,
while MCP resources logic remained in `Server`
## Motivation and Context
1. Fix the multiple connection issues reported for SSE transport
2. Avoid server duplications during configurations: currently every connection
creates a session, but the server stays single
## How Has This Been Tested?
Added `SseIntegrationTest` and `WebSocketIntegrationTest` integration
tests to check connection with single and multiple clients
## Breaking Changes
This change caused several depreciations:
1. The `Server` -> `Protocol` inheritance (which caused single
connection issue) should be removed in future releases, now, all the
methods inherited from `Protocall` marked as `Deprecated` with a
`Warning`
2. Websocket Ktor server initialization changes in order not to create
server instance per connection

#196 Update build configuration and workflows for enhanced local
publishing and sample builds
- Add `mavenLocal()` to repository configuration in sample projects.
- Update dependencies to distinguish between `mcp.kotlin.client` and
`mcp.kotlin.server`.
- Include `JAVA_OPTS` for optimized memory usage in GitHub workflow.
- Enhance build workflow to include local publishing and build steps for
sample projects.
- Add package-lock.json for Kotlin JS/WASM Store
- Switch to SNAPSHOT versions by default
## Motivation and Context
#196 Samples MUST be validated as part of the build
## How Has This Been Tested?

./gradlew :kotlin-sdk-core:publishToMavenLocal
./gradlew :kotlin-sdk-client:publishToMavenLocal

## Motivation and Context
Flaky integration tests
## How Has This Been Tested?
`./gradlew check`
## Changes
- Use random port for Ktor in tests
- Remove unused `TestUtils` utility class.
- Replace `runTest` with `runBlocking` in test cases.
- Adjust imports and formatting for consistency.
- Add `Awaitility` dependency for dynamic server setup.
- Update `Duration` usage from milliseconds to seconds.
- Minor configuration and code formatting updates.
## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [x] Test update
## Checklist
<!-- Go over all the following points, and put an `x` in all the boxes
that apply. -->
- [ ] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [ ] My code follows the repository's style guidelines
- [ ] New and existing tests pass locally
- [ ] I have added appropriate error handling
- [ ] I have added or updated documentation as needed
## Additional context
<!-- Add any other context, implementation notes, or design decisions
-->
<!-- Provide a brief summary of your changes -->
Replace the CIO dependency with only server/client core dependency.
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
In order to minimize the size of package. There are probably other
existing engines like Netty/Tomcat(server) or Java/OkHttp/Apache(client)
in the classpath. So we can reuse existing infrastructure.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
I have run:
- kotlin-sdk-client: jvmTest, jsTest
- kotlin-sdk-test: jvmTest, jsTest
- kotlin-sdk-server: allTests
- All `build` of samples
I have an issue about `samples/kotlin-mcp-server`.
`io.modelcontextprotocol` is not found in `commonMain`.
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
Yes. They need to `implementation` CIO engine manually if they use it in
their app.
