Passthrough of new entries from source feed to output feed via

SSRF protection for source feed URLs — DNS resolution and IP range
validation before connecting.
HTTP 429 (Too Many Requests) detection — treated like 304, falls
back to cached feed.
Source feed deduplication across tasks sharing the same URL.
Canonicalization of output and cache directory paths.
ETag and Last-Modified header persistence for conditional feed
fetches.
Configurable User-Agent header via

userName option.
A GitHub Action workflow to generate and host the generated feeds on
GitHub Pages.
Changed
Cache files are now per-task instead of per-source, enabling
different saveSourceFeedEntries per task for the same
source URL. Old cache files are migrated automatically to the new file
names.
Fixed
HTTP retry for server errors — retry logic was previously broken
because 5xx exceptions bypassed the retry loop. Server errors are now
properly retried with exponential backoff.
Statically-linked build for AArch64 — the Nix GC root was not being
created.
