fix: dedupe Windows notification quick replies (#3467)

[Moku151]

Closes #3467

Summary

This restores the notification reply deduplication introduced in #3420, which was included in 4.15.6 but was not forward-ported to dev and is therefore missing from 4.16.0.

On Windows, Electron can emit the reply event twice for a single notification quick reply, causing the message to be sent twice.

This PR:

• dispatches only the first reply event for a notification;
• resets the deduplication state when the notification is shown again;
• adds regression tests for duplicated reply events and subsequent valid replies.

Screenshots

Not applicable; this change affects notification event handling only.

Summary by CodeRabbit

• Bug Fixes

  • Prevented duplicate notification replies from being processed more than once.
  • Replies are accepted again when a notification is shown anew.

• Tests

  • Added coverage for duplicate reply handling and valid replies after a notification reappears.

Walkthrough

The notification reply handler now prevents duplicate dispatches for the same notification. Showing the notification again clears the guard. Tests cover duplicate replies and replies after a subsequent show event.

Changes

Notification reply deduplication

Layer / File(s)	Summary
Reply dispatch guard src/notifications/main.ts	Tracks replied notification IDs, resets the tracking state on show, and ignores duplicate reply events.
Reply guard validation src/notifications/main/setup.main.spec.ts	Verifies one dispatch for repeated replies and a new dispatch after the notification is shown again.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 5e481

A notification that is closed and shown again with the same tag may have its first valid quick reply ignored, preventing the user’s message from being sent. This bounded correctness issue should be fixed and covered by a regression test before merging.

Hi @jeanfbrito, this PR forward-ports your fix from #3420, which was present in 4.15.6 but missing from dev and 4.16.0. Could you please review it when you have time? Thanks!

[jeanfbrito]

This matches the #3420 / 4.15.6 guard: drop a second reply for the same notification id, re-arm on show. Do not clear the Set on close (the duplicate can arrive after dismiss).

The two specs cover the cases that matter. Approving. Closing #3469 in favor of this.

Note: validate-pr is waiting on workflow approval for first-time contributors — I will kick that so CI can run.

Thank you @Moku151
