- Ported advanced error detection (`is_auth_error`, `is_transient_error`, `is_network_error`) from the daemon script to accurately classify exceptions.
- Implemented `get_rate_limit_wait_seconds` to intelligently parse HTTP rate-limit headers (`retry-after`, `ratelimit-reset`) instead of relying on static backoffs.
- Increased default login retry attempts to 5, with jitter and bounded delays.
- Updated `login_with_backoff` to fail fast on invalid credentials while gracefully handling transient network issues and rate limits.
- New standalone script `bsky_post.py` to post text + optional image
or video to a Bluesky PDS instance. Supports --image, --video (mutually
exclusive), --alt, --lang, --service, --username, --password flags.
Reuses the same login-with-backoff pattern as rss2bsky and the Twitter bot.
- New Jenkinsfile that triggers every Thursday at 07:15 (cron: 15 7 * * 4),
reads credentials from Jenkins secret text entries, and runs bsky_post.py
with the configured image and Catalan language tag.
- Changed `post_lang: str` to `post_langs: List[str]` in `run_once`
and `try_send_post_with_variants` to support multiple BCP-47 language
tags passed to Bluesky's `langs=` field.
- Updated `--lang` CLI argument to accept comma-separated language codes
(e.g. `--lang ca,es`), parsed into a list at startup. Defaults to `["ca"]`.
- Added startup log line reporting the configured language(s) per run.
