Implement interfaces from GithubApi for all public classes

[codexcoder21]

Summary

• ~150 public classes now implement their corresponding interfaces from community.kotlin.conrib.github, extracted into the separate GithubApi project. Each class (e.g. GHApp, GHRepository, GHPullRequest) now has an implements community.kotlin.conrib.github.<ClassName> clause, enabling consumers to program against stable interfaces rather than concrete implementations.

• Enums, exceptions, and existing interfaces removed from org.kohsuke.github — these types (e.g. GHEvent, GHCommitState, GHDirection, GHException, HttpException, Reactable, Refreshable, TrafficInfo, and ~20 others) now live in the GithubApi project and are imported from community.kotlin.conrib.github.

• Added community.kotlin.conrib:github-api:1.0.0-SNAPSHOT as a Maven dependency in pom.xml to provide the interface definitions, enums, and exceptions.

• Updated all test files to import enums, exceptions, and interfaces from the new community.kotlin.conrib.github package.

Files changed

• 230 files changed: 576 insertions, 1,690 deletions
• ~150 Java classes modified to add implements clauses and new imports
• 32 files deleted (enums, exceptions, interfaces that moved to GithubApi)
• ~30 test files updated with new import paths
• pom.xml updated with GithubApi dependency

Test plan

• All 537 existing tests pass with the interface implementations
• Verify Maven can resolve the community.kotlin.conrib:github-api:1.0.0-SNAPSHOT dependency
• Verify no runtime class loading issues from the package restructuring
• Confirm deleted enum/exception/interface types are correctly resolved from the GithubApi dependency
