Add manual workflow to mark all syndication cache entries as sent

[Copilot]

• Create .github/scripts/mark-all-sent.js — marks all cache entries (and optionally live feed items) as sent for all platforms
• Create .github/workflows/mark-all-sent.yml — manual workflow_dispatch action that restores cache, runs the script, and saves the updated cache
• Fix: defensively initialize cache[type] and cache[type][itemId].platforms in markAllPlatformsSuccessful to handle partial/corrupt cache files
• Fix: use a Set per content type to track unique item IDs, preventing double-counting when alsoFetchFeeds overlaps with existing cache entries
• Fix: readCache() now distinguishes ENOENT (bootstrap fresh) from a corrupt/unparseable file (throw with a clear message) to prevent silent data loss
• Fix: feed fetch failures are now hard errors (re-throw) when alsoFetchFeeds is enabled so the workflow exits non-zero instead of silently succeeding with incomplete data

Pull request overview

Adds a manual, dispatch-only GitHub Actions workflow plus a companion script to bulk-update the syndication cache (.github/cache/syndication-status.json) so existing posts/links are treated as already sent across supported platforms, with optional live-feed fetching and a dry-run mode.

Changes:

• Introduces .github/scripts/mark-all-sent.js to stamp cache entries (and optionally feed items) as successful across the relevant platforms with a markedManually flag.
• Adds .github/workflows/mark-all-sent.yml to run the script via workflow_dispatch, reusing the existing syndication cache restore/save and concurrency patterns.

Done in e0981a5. Two fixes were applied to mark-all-sent.js:

1. Defensive initialization — markAllPlatformsSuccessful now checks that cache[type], cache[type][itemId], and cache[type][itemId].platforms each exist and are objects before writing to them, so a partial or corrupt cache file won't cause an uncaught TypeError.

2. Accurate unique-item counts — replaced the separate cacheCount/feedCount integers with a per-type Set of item IDs. Both the existing-cache pass and the live-feed pass add to the same set, so overlapping items are counted exactly once and the dry-run totals reflect the real number of unique items changed.

Done in 5470f49. Both reviewer comments from that thread are addressed:

1. readCache() no longer swallows all errors — it now catches only ENOENT (file absent → bootstrap fresh) and re-throws any other I/O error. If the file exists but cannot be parsed, it throws with a clear message identifying the cache path, so the workflow fails rather than silently overwriting recoverable state.

2. Feed fetch failures are now hard errors — when alsoFetchFeeds is true the try/catch around fetchFeed is gone; the error propagates to main() and then to the top-level .catch(), causing the process to exit non-zero. The workflow will fail visibly instead of succeeding with only the existing cache entries marked.
