Fix WhatsApp phone parsing crash

[mralonsocorona]

Summary

Fixes a crash in the WhatsApp extension phone parsing helper when the default country preference is missing.

The parseUserPhone helper previously called .trim() directly on the configured defaultCountry. When that preference is unavailable, the Open Chat command can crash while parsing search input.

Changes

• Allow parseUserPhone to safely handle missing input.
• Guard the defaultCountry preference before trimming it.
• Keep existing behavior for international numbers and configured default countries.
• Add a changelog entry using {PR_MERGE_DATE}.

Validation

• npm run lint
• npm run build

Fixes #28921
Fixes #28918

Greptile Summary

Guards parseUserPhone against a crash when input is undefined or defaultCountry is missing from preferences, fixing the Open Chat command crash reported in #28918/#28921.

• parsePhone.ts: input is now optional; both input?.trim() ?? "" and defaultCountry?.trim() use optional chaining so a missing preference no longer throws.
• CHANGELOG.md: Adds a Fix entry, though the date placeholder should be {PR_MERGE_DATE} rather than a hardcoded date.

Confidence Score: 5/5

Safe to merge; the logic change is minimal and directly addresses the crash without altering any happy-path behavior.

The fix is a small, targeted defensive change — optional chaining on two values that were previously assumed non-null. No existing behavior is altered for users who have the preference set, and the empty-string fallback for undefined input produces a valid { isValid: false } result from the phone library rather than throwing.

CHANGELOG.md needs the date placeholder corrected before merge.

Important Files Changed

Filename	Overview
extensions/whatsapp/src/utils/parsePhone.ts	Makes input optional and guards both input and defaultCountry with optional chaining; correctly fixes the crash reported in the linked issues.
extensions/whatsapp/CHANGELOG.md	New Fix entry uses a hardcoded date (2026-06-25) instead of the required {PR_MERGE_DATE} placeholder.
