Document PHP optimizer standards violations for future fixes

DOCUMENTATION UPDATE:

Added standards_violations section to PHP optimizer documentation:
- MISSING: set -eo pipefail (bash strict mode)
- VIOLATION: Using cecho/echo -e (198 instances) instead of print_* functions
- MISSING: Cancel buttons (uses 'q) Quit' instead of '0) Cancel' pattern)
- UNKNOWN: press_enter() usage needs verification

Marked fix_required: Yes - refactor needed

These violations were identified after completion. Script is functional
but does not follow toolkit coding standards from REFDB_FORMAT.txt.

NOTE TO SELF: Always read [CRITICAL_DESIGN_RULES] section of
REFDB_FORMAT.txt BEFORE writing new scripts.
