fix: reconcile documentation with actual behavior

[josegonzalez]

The review tracked in #374 surfaced six documented behaviors the code did not implement. Where the documentation was the intended spec, the code now matches it: apply and plan fetch a recipe from an http(s) --tasks URL (fetched once per command and reused across flag parsing and execution), and docket init writes a play-level name so --play resolves after scaffolding. The apply marker table, the play-skipped summary, the vars-file bool coercion forms, and the WSL install destination were corrected in the docs to match the code.
