fix: enable publish dedup by default, add source-URL dedup, forward pre-selected taxonomies

[chubes4]

Summary

• Publish dedup enabled by default — dedup_enabled now defaults to true and treats missing config as enabled. No more opt-in malarkey.
• Source URL dedup — published posts store _datamachine_source_url meta. The datamachine/check-duplicate ability checks source URL before title similarity, preventing same-source republishing even with different AI-rewritten titles.
• Pre-selected taxonomy forwarding — the WordPress publish handler now passes pre-selected taxonomy selections (e.g., fixed festival/location assignments) through to the publish ability. Previously only ai_decides selections were forwarded.
• Respects link_handling config for source attribution instead of always appending.

Root cause

Wire was publishing 3 copies of the same Reddit thread because:

1. Triple root jobs were spawned per scheduled run (fixed by batch_state_missing fix in v0.42.0)
2. Parallel fetches grabbed the same data before processed-items could mark it
3. Publish dedup was disabled by default so nothing caught it downstream
4. Pre-selected taxonomies were silently dropped, leaving ~300 Wire posts without festival/location

Testing

• Added test_check_duplicate_finds_published_post_by_source_url to DuplicateCheckAbilityTest
