Adds github.com/danmestas/EdgeSync/cli/repo, a kong-compatible command tree for fossil repo operations (ci, co, timeline, diff, cat, config, merge, …) that consumers can embed without importing libfossil/cli.

Cmd and Globals are type aliases of libfossil/cli.RepoCmd and libfossil/cli.Globals. Re-declaring them as wrapper structs would require mirroring ~38 subcommands' worth of kong flags by hand, brittle to libfossil flag changes. Aliases give consumers source-level isolation (no "github.com/danmestas/libfossil/cli" import in their code) while reusing libfossil's tested CLI implementation.

cmd/edgesync/cli.go migrates to the new package as the first consumer. The flag surface, subcommand set, and behavior are unchanged from the end-user perspective.
