Replace all ad-hoc inline comments between license headers and function
declarations with consistent SYNOPSIS / DESCRIPTION / ARGUMENTS / RETURNS /
EXAMPLE blocks across all 99 project-owned functions/ files. No executable
logic, variable names, or exit codes were modified.
Completes Task #6 from AGENTS.md (Retroactive Function Documentation
Standardization).
Adds a robust `scrub` utility function to safely and recursively clean
up common OS metadata, development caches, editor artifacts, and slicer
cruft using `fd`.
Features:
- Hierarchical deletion fallback system: checks for a custom `rm`
function, falls back to `trashy` (trash put), then `trash-cli`,
and drops to standard `rm -rf` as a final measure.
- Safe `-d/--dry-run` modes to preview matched targets.
- An advanced `-a/--aggressive` mode for wiping heavy project caches
(node_modules), local logs, and custom AI runtime config histories.
- Full flag validation and colorized help menus.
