Removes internal process references so the repo is presentable to an outside audience: dropped the internal build-retrospective doc (process log with internal terms, not useful to an outside reader), and reworded remaining internal references in code comments and module docs (agents.md cards, architecture.md, MODULES.md, index.html, package.json) to generic descriptions of what changed and when, with no behavior change -- full 47/47 suite re-run green after the scrub, every edit verified comment/doc-only via diff.

/* ISLE SLINGERS -- physics/aim/index.js (submodule: aim)
|
|
* Modularization pass (behavior-neutral split of the original
|
|
* js/core.js monolith). Installs its units into ONE shared physics scope `P`
|
|
* that every physics submodule sees -- the same single-scope semantics the
|
|
* monolith had. Must load before js/physics/index.js (the aggregator that
|
|
* attaches the public ISLE_CORE API). Surface installed: aimVector, trajectory.
