* refactor: a transport trait and streamable http client
* test: test with js streamable http server
* refactor: separate sse stream connection
* fix(test): streamable http client test with js
* fix(test): wait longer time for js server startup
* feat(model): add json schema generation support for all model types
This commit adds JSON Schema support for all model types by implementing
`schemars::JsonSchema` trait. The feature is gated behind the new
`schemars` feature flag. This enables automatic schema generation for
API documentation and validation purposes. Added tests to verify schema
generation for client and server JSON-RPC messages.
* fix(model): add manual json schema implementation for `NumberOrString`
This commit adds a manual implementation of `JsonSchema` trait for the
`NumberOrString` enum to properly represent its union type nature in
JSON Schema. The schema now correctly specifies that the type can be
either a number or a string using the `oneOf` validation keyword.
* fix(model): skip extensions field in json schema generation
The `Extensions` type was incorrectly included in JSON schema
generation, which could lead to confusing API documentation. This commit
adds `#[schemars(skip)]` attribute to all `extensions` fields in request
and notification structs, and removes the manual `JsonSchema`
implementation for the `Extensions` type since it's an internal
implementation detail that shouldn't be exposed in the schema.
* feat(transport): support streamable http server
* refactor(transport): add common module for shared transport utilities
* perf(tracing): add more log for streamable http session
* fix(test): fix port conflict in test with js
* fix(transport): fix id generating and session management
1. cancel when deleting
2. use `wrapping` and `saturating` correctly
* chore(naming): rename sse server to streamable http server
