Parse the occurrence field from sub_row and skip execution when today
is not the nth weekday specified (e.g. first_sunday). Check runs after
sub_row fetch but before dupe guard. Two new tests confirm skip and
pass paths using patched date.today in app.services.poster.
Adds RedditCommentStrategy to app/services/platforms/reddit_comment.py,
resolving thread_id via thread_url_override or _find_sticky title search,
falling back to reconstructed URL when client.comment() returns empty string.
Registers the strategy under "reddit_comment" in the platform _REGISTRY.
7 new tests confirm all execution paths: url override, title pattern lookup,
not-found error, missing-extra error, empty-URL reconstruction, dupe guard,
and registry presence. Full suite: 34/34 passing.
Replace hardcoded platform dispatch with get_client(campaign["type"]) so
any future campaign type (blog_post, email, etc.) routes automatically
through the strategy registry. Adds dupe-guard opt-out per strategy,
sub_row pre-fetch for extra metadata, and 5 new TDD tests (14 total).
