Description

When using --reminder flag with gog calendar create or update, the API returns: "Google API error (400 cannotUseDefaultRemindersAndSpecifyOverride): Cannot specify both default reminders and overrides at the same time."

Steps to Reproduce

gog calendar create primary --summary "Test Event" --from "2026-01-19" --to "2026-01-19" --all-day --reminder="popup:7h"
gog calendar update primary <eventId> --reminder="" --json

Expected Behavior

Event should be created with the specified reminder override (reminders.useDefault: false and reminders.overrides: [{method: "popup", minutes: 420}]).

Actual Behavior

Google API error (400 cannotUseDefaultRemindersAndSpecifyOverride): Cannot specify both default reminders and overrides at the same time.

Environment

• gog version: v0.8.0 (4f2b12e)
• OS: macOS

Analysis

It appears gog is sending both reminders.useDefault: true AND reminders.overrides in the same request, which the Google Calendar API doesn't allow.
