As part of the ongoing technical debt cleanup, this commit modernizes
CPTimer.j by removing its reliance on the C-preprocessor and updating
syntax to modern JavaScript standards.
Key changes:
- Replaced `#define CPTimerDefaultTimeInterval` with a native `const`.
- Replaced `var` with `const`/`let` for proper block scoping and immutability.
- Replaced the build-time `PLATFORM(DOM)` guard with a runtime
`typeof(window) !== 'undefined'` check, ensuring Foundation does not
depend on build-time platform flags.
- Added `FIXME` comments to explicitly document architectural anti-patterns:
- The invasive global override of `window.setTimeout` and `window.setInterval`.
- The use of `new Function` for string evaluation (CSP violation).
- The questionable exposure of `CPTimerDefaultTimeInterval` as a fallback.
