Native nostalgia stack

Apply only the contract material to the requested work. Project AGENTS and docs own implementation rules and exact commands; project-structure/SKILL.md owns language-neutral layout and documentation.

Compiler and layout

• Use the project-pinned latest stable FPC and Delphi mode unless project docs explicitly choose another mode.
• Keep project-wide compiler directives in one shared include used by every unit.
• Put Pascal source under one root (source/ preferred), using namespaced filenames and a flat layout until a namespace becomes unwieldy.
• Co-locate unit tests; keep delivered end-to-end corpora under root tests/.
• Put all ignored build output under root build/.
• Prefer executable InstantFPC for one-off Pascal scripts; use an existing task runner or dynamic language only when that is materially simpler.
