Consolidate workspace_root, PlannedCommand, shell_arg, markdown_cell, and
replace_generated_region into commands/mod.rs; unify fabro_dev/output_text/
write_file/read_file into tests/it/main.rs. Drop the abandoned check-boundary
subcommand.

Add a settings reference generator backed by OptionsMetadata on the sparse config layer structs. The generated user-configuration page is fenced and checked in CI alongside the CLI reference.
Add a cargo dev generator for the CLI reference and gate the generated docs in CI. The generator reads the fabro clap command tree through a narrow public reference surface so CLI docs drift is caught without exposing runtime command internals.
