Bug: docs/design/notifications.md still describes persisted snooze state after #75 fix

[JoshuaRowePhantom]

Summary

The fix for #75 updated the code and JSON schema correctly, but did not update the design document.

What needs to change in docs/design/notifications.md

1. Line 36 - Remove "Persisted per-tab in the user-computer-profile entity." from the IsSnoozed docstring. Replace with "Snooze state is in-memory only and resets on restart."

2. Lines 159-160 - Remove the persistence paragraph in the Snooze section:

   "Snooze state is persisted per tab key in the user-computer-profile entity under a snoozed-notification-tabs string array field."

3. Line 259 - Remove the file checklist entry:

   "JsonSchemas/user-computer-profile.json -- add snoozed-notification-tabs string array field"

4. Line 264 - In Non-goals Bump actions/checkout from 4 to 7 #1, change "snooze state is persisted" to "snooze state is not persisted" (or rewrite to clarify it resets on restart).

Why

Issue #75 required removing all design-doc references to persisting snooze state, but the commit only modified the schema file and a code comment. The design doc is the authoritative spec and still documents the wrong behaviour.

Design

Root cause: The fix for #75 updated the code and JSON schema to remove persisted snooze state, but left four stale references in \docs/design/notifications.md.

Approach: Update the design doc only — no code changes needed.

Files that will change:

• \docs/design/notifications.md\ — fix four stale references to snooze persistence

[JoshuaRowePhantom]

Tests

This is a documentation-only fix. No tests are needed — there is no code to verify.

Resolution

Root cause: The fix for #75 updated code and the JSON schema to remove persisted snooze state, but left four stale references in \docs/design/notifications.md\ describing the old persisted behaviour.

Changes:

• \docs/design/notifications.md\ — (1) Updated \IsSnoozed\ doc-comment from 'Persisted per-tab in the user-computer-profile entity.' to 'Snooze state is in-memory only and resets on restart.'; (2) Removed the two-line persistence paragraph from the Snooze section; (3) Removed the \JsonSchemas/user-computer-profile.json\ source-layout entry; (4) Rewrote Non-goals Bump actions/checkout from 4 to 7 #1 to state that both notifications and snooze state are in-memory only and reset on restart.

Deviations from design: None.

Commit: a59e63e

Note: Two pre-existing flaky tests observed during test runs (unrelated to this change): #409, #410.

Verification passed

Checked: Commit a59e63e on the \eatures\ branch, modifying \docs/design/notifications.md.

Result: All four changes described in the issue are present and correctly implemented:

1. \IsSnoozed\ doc-comment updated from 'Persisted per-tab in the user-computer-profile entity.' to 'Snooze state is in-memory only and resets on restart.'
2. Persistence paragraph ('Snooze state is persisted per tab key...') removed from the Snooze section.
3. \JsonSchemas/user-computer-profile.json\ source-layout entry removed.
4. Non-goals Bump actions/checkout from 4 to 7 #1 rewritten to state both notifications and snooze state are in-memory only and reset on restart.

This is a documentation-only fix; no code changes or tests are required.
