fix: remove duplicate ICT and PHT timezone entries

[Koan-Bot]

What

Removes duplicate ICT (Indochina Time) and PHT (Philippine Time) definitions from @Zone in Time::Zone.

Why

Both timezones were defined twice with identical values. The second definition silently overwrites the first — no behavioral change, but it's confusing and suggests a copy-paste error during a previous timezone addition.

Testing

Full test suite passes (28 files).

Greptile Summary

Removes two duplicate key-value pairs ("ict" and "pht") from the @Zone array in lib/Time/Zone.pm. In Perl, %Zone = @Zone means duplicate keys are silently overwritten by the last occurrence, so there was no behavioral change — this is purely a cleanup of redundant copy-paste entries.

Confidence Score: 5/5

Safe to merge — purely cosmetic deduplication with no behavioral change.

The removed entries had identical values to the retained entries; the hash initialization semantics in Perl (%Zone = @zone) already silenced the first duplicate. No logic, values, or external contracts change.

No files require special attention.

Important Files Changed

Filename	Overview
lib/Time/Zone.pm	Removes the first (less-descriptively commented) duplicate definitions of "ict" (Indochina Time, +7h) and "pht" (Philippine Time, +8h); no functional change since %Zone = @zone would already keep the last occurrence.
