refactor(config): remove github_repo_directory and github_repo_url (#8)

Drop the github_repo_directory and github_repo_url configuration
attributes and all their plumbing. These were largely informational:
github_repo_url only ever appeared in prompt text (system prompt and
Telegram Quick Facts), and github_repo_directory added prompt text plus
a Telegram-only os.Chdir into the project tree.

Removed across the precedence chain:
- Config file keys, ODEK_GITHUB_REPO_* env vars, and --github-repo-dir /
  --github-repo-url CLI flags (internal/config/loader.go, cmd/odek/main.go)
- CLIFlags, Config, and ResolvedConfig struct fields plus expandEnv/merge
  handling
- System prompt repo context block (buildSystemPrompt)
- REPL repo hint, Telegram Quick Facts source line, Telegram chdir, and
  the /new repo line
- Config template entry and help text
- Associated test references
