improve PR #246 - part 1

Fixed links between rules and guidelines.

Add guideline about "Rule 2 - Size restrictions" not changing soon.

Expand "Guidelines for Rule 13 - No carriage returns in prog.c".

Put the word, "restrictions" into "Rule 2 - Size restrictions".
While this is a **GOOD IDEA**, the concept needs to be rolled out
over all of the rules, not just "Rule 2 - Size restrictions".

Changed IOCCC Rules to version **29.13 2025-12-01**.
Changed IOCCC Guidelines to version **29.06 2025-12-01**.

Ran `make quick_www` to perform the above.
