docs: list the Kotlin and TypeScript ADK implementations in README - #1212

…1212)

The Important Links header offers Python ADK and Java ADK but predates the
Kotlin and TypeScript implementations, so readers looking for a sibling
language find an incomplete list. Add both, and drop a stray trailing space
on the Java line.

* feat: enable h2c on web launcher listener (#826)

* feat(web): enable h2c on launcher listener

- Configure the web launcher HTTP server with net/http.Protocols so the same listener accepts both HTTP/1 and cleartext HTTP/2 traffic.
- This keeps existing REST, Web UI, A2A, and trigger routes working over HTTP/1 while allowing custom web sublaunchers to register handlers that require h2c, including native gRPC servers. The change avoids any public launcher API changes  and uses the standard library instead of adding an http2/h2c dependency.
- Add a regression test covering existing HTTP/1 route handling through the base router.

* feat(launcher): add opt-in h2c support for web server

* test(launcher): cover opt-in h2c behavior

Test HTTP/1.1 and prior-knowledge h2c requests with the flag enabled and disabled. Clarify h2c security, upgrade, and streaming timeout behavior in the flag documentation.

* fix(launcher): handle response body close errors in h2c tests

(cherry picked from commit e6562fe)

* fix(skilltoolset): document load_skill param as name, not skill_name (#919)

* fix(skilltoolset): document load_skill param as name, not skill_name

The default system instruction told the model to call the load_skill tool
with skill_name="<SKILL_NAME>", but LoadSkillArgs marshals its field as
"name". The first load_skill call in each session was therefore rejected for
an unknown field and only recovered via retry. Use name= to match the schema.

* fix(skilltoolset): make the new instruction test compile and pass lint

The test file added here imported the pre-v2 module path, which no longer
exists, so the whole skilltoolset package failed to build:

    tool/skilltoolset/instruction_test.go:8:2: no required module provides
    package google.golang.org/adk/tool/skilltoolset/internal/skilltool

Point the import at google.golang.org/adk/... and add the Apache 2.0
header that goheader requires on every new Go file.

No change to the test's logic or to the instruction fix.

* docs(llmagent): correct OutputSchema comment — tools still work via set_model_response (#786)

The previous comment incorrectly stated that OutputSchema prevents the use of
tools. The framework injects a set_model_response tool transparently so all
tool types (function tools, RAG, agent transfer) continue to work alongside
structured output. Updated the comment to reflect actual behavior.

Fixes #756
