Avoid getCalendarById on HarmonyOS to fix isPrimary column error

[robertying]

HarmonyOS 4.2.0 does not expose the isPrimary column directly in the calendar content provider — it's only available as a COALESCE expression. expo-calendar's native getCalendarById queries this column, causing an IllegalArgumentException crash when syncing assignments on Huawei devices.

Replace Calendar.ExpoCalendar.get(calendarId) with Calendar.getCalendars() followed by a find-by-id lookup, which uses a different native code path that does not query isPrimary directly.

Fixes #1112

@claude can you fix and patch the source instead?

Tasks

• Gather context and understand the request
• Locate the native expo-calendar source for patching
• Create a patch for the HarmonyOS isPrimary column bug
• Revert the JS-level workaround in src/helpers/event.ts
• Commit and push changes

I'm unable to create the patch in this run because:

1. node_modules are not installed — the workflow doesn't run pnpm install, so there are no local expo-calendar source files to diff against.
2. Network access is blocked — npm, curl, gh api, and WebFetch all require explicit permission grants that aren't configured for this action.

patch-package patches require exact line-by-line diffs matched against the installed source; I can't synthesize one without the original file.

What the patch would do

The fix is in node_modules/expo-calendar/android/src/main/java/expo/modules/calendar/CalendarModule.kt (or a helper class). The getCalendarByIdAsync function queries the Android calendar content provider with isPrimary in its column projection, which crashes on HarmonyOS where that column is only available as a COALESCE expression. The getCalendarsAsync function avoids this by not including isPrimary directly in its projection.

The patch would change the getCalendarByIdAsync projection to either:

• Remove isPrimary (matching what getCalendars does), or
• Wrap it: "COALESCE(isPrimary, 0) AS isPrimary"

To unblock this

Add a pnpm install step to the workflow before the Claude Code step, or add Bash(npm:*) / Bash(curl:*) to claude_args in .github/workflows/claude.yml:

- name: Install dependencies
  run: pnpm install --ignore-scripts
  
- name: Run Claude Code
  uses: anthropics/claude-code-action@v1
  with:
    claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}

Or alternatively:

claude_args: '--allowed-tools Bash(npm:*) WebFetch'

Once node_modules are available I can run npx patch-package expo-calendar after editing the file to auto-generate the correct patch.
