* feat(gitea): add Gitea Go SDK integration and CLI commands
Add `code.gitea.io/sdk/gitea` and create `pkg/gitea/` package for
connecting to self-hosted Gitea instances. Wire into CLI as `core gitea`
command group with repo, issue, PR, mirror, and sync subcommands.
pkg/gitea/:
- client.go: thin wrapper around SDK with config-based auth
- config.go: env → config file → flags resolution
- repos.go: list/get/create/delete repos, create mirrors
- issues.go: list/get/create issues and pull requests
- meta.go: pipeline MetaReader for structural + content signals
internal/cmd/gitea/:
- config: set URL/token, test connection
- repos: list repos with table output
- issues: list/create issues
- prs: list pull requests
- mirror: create GitHub→Gitea mirrors with auth
- sync: upstream/main branch strategy (--setup + ongoing sync)
