Add TUI add and preview commands

Use charmbracelet/huh for an interactive add flow. Add a preview
subcommand to enter/exit per-project pre-release tags. Move stamp.toml
into .stamp/ and add ConfigPath helper. Prefer --snapshot then project
PreTag when computing versions and promote bumps to pre-release when
appropriate. Export CurrentVersion and add required TUI deps to go.mod.
