This pull request adds the 11 Slackbot skills Web API methods to the sync and async clients.

• slackbot.skills.create, .delete, .info, .library.add, .library.remove, .list, .update (skills:read / skills:write)
• admin.slackbot.skills.list, .publish, .setAutoEnabled, .unpublish (admin.skills:read / admin.skills:write)
• New com.slack.api.model.slackbot.Skill model, shared by the create, info, list and update responses, plus SkillMcpServer for the mcp_servers argument.
• Request field Javadoc copies the argument descriptions from the docs.slack.dev reference pages.
• Response fields are typed from the docs examples and confirmed against live responses. This adds invalid_mcp_servers (create and update) and invalid_usergroup_ids (setAutoEnabled), which the docs name in the errors table but don't show in an example.
• mcp_servers is sent as a JSON array of {service_type, app_id, server_id} objects. The reference pages only say "array". The API rejects plain strings ("must provide an object") and any other keys ("invalid additional property"). An empty list sends [], which clears the list on update.
• skill_ids, creator_ids and usergroup_ids are sent comma-joined, like other ID arrays in this SDK.
• JsonDataRecorder now writes a typed sample for empty mcp_servers arrays instead of "".

Testing

The new test_with_remote_apis tests were run against an Enterprise Grid developer sandbox using an org-installed test app:

mvn test -pl slack-api-client '-Dtest=test_with_remote_apis.methods.slackbot_skills_Test,test_with_remote_apis.methods_admin_api.AdminApi_slackbot_skills_Test'

• slackbot_skills_Test uses SLACK_SDK_TEST_BOT_TOKEN (needs canvases:write, skills:read, skills:write). It creates a skill from instructions, then calls info, update (including an unknown MCP server), owned list, library remove and add, and delete. It also turns a new canvas into a skill and deletes it, and runs async list and info.
• AdminApi_slackbot_skills_Test uses SLACK_SDK_TEST_GRID_ORG_ADMIN_USER_TOKEN (needs admin.skills:read, admin.skills:write, skills:write). It lists with each sort, then creates a skill, publishes it, runs a partial publish to check failed_skills, and auto-enables it. With SLACK_SDK_TEST_GRID_IDP_USERGROUP_ID_2 set it also auto-enables for a user group and checks an unknown group. Finally it sets no_one, unpublishes, and deletes the skill.
• Both tests pass with setFailOnUnknownProperties(true), and every test skill is deleted at the end.
• The existing test apps need these scopes added before the tests pass in the full remote suite.

A note on placement: the slackbot.skills.* methods come before slackLists.* in Methods, MethodsClient, AsyncMethodsClient, both implementations, MethodsRateLimits, RequestFormBuilder and MethodsTest, because method names are sorted case-insensitively. slackbot (b) sorts before slackLists (l). This matches the Node and Python SDKs. The exception is metadata/web-api/rate_limit_tiers.json, which RateLimitsDumpTest generates in case-sensitive order, so there slackLists.* stays first.

Closing in favor of a stack with one pull request per method, following a skill from creation to deletion: #1685 through #1695. The branch is kept.
