Experimental Livebook-friendly DSL for sketching project plans.

This Lab DSL compiles to the stable, pipe-first Choreo.Planner builders and returns an ordinary %Choreo.Planner{}. It is useful for interview planning, release sketches, dependency conversations, and quick Kanban/Gantt artifacts.

Examples

iex> import Choreo.Lab.DSL.Planner
...> plan = planner "Launch v1" do
...>   v1 = milestone("V1 Launch")
...>   design = task("Design API", status: :done, estimate_hours: 8)
...>   build = task("Build Gateway", priority: :high)
...>   alice = user("Alice")
...>   backend = label("backend")
...>
...>   contains v1 ~> design
...>   contains v1 ~> build
...>   design ~> build |> depends_on()
...>   build ~> alice |> assigned_to()
...>   build ~> backend |> tagged_with()
...> end
iex> Enum.sort(Choreo.Planner.children(plan, :v1))
[:build, :design]
iex> Choreo.Planner.dependencies(plan, :build)
[:design]
iex> Choreo.Planner.assignee(plan, :build)
:alice

Edges use the same sketch grammar as the other Lab DSLs:

design ~> build
design ~> build |> depends_on("finish design first")
blocks blocker ~> blocked
contains milestone ~> task
assigned_to task ~> user
tagged_with task ~> label

Planner edge labels are accepted for grammar consistency, but the stable Choreo.Planner model currently stores typed relationships rather than display labels on those edges.
