v1.1.0 - Caption quality: trait pruning + tag-based curation

Your captions, under control

• Blacklist: tags like watermark, signature, blurry never enter captions.
• Trait pruning: set Prune ≥ 0.8 and tags present in ≥80% of images (blue hair, twintails…) are removed from every caption — the trigger word absorbs the character's constant traits. The pruned list shows up in _report.html.
• Tag-based curation: Require 1girl / Reject if multiple girls — frames that fail the rules are moved to output/_rejected/ automatically. The tagger now curates your dataset, not just captions it: no more group-shot pollution from gameplay/anime sources.
• Always-tags (tag_always config / --always): fixed tokens after the trigger, e.g. anime screencap.
• Everything also works standalone: vid2dataset tag FOLDER --require 1girl --exclude "multiple girls" --prune-threshold 0.8

屏蔽标签、特征修剪（触发词吸收固定特征）、按标签自动剔除多人/不合格帧到 _rejected/ —— 打标器现在不只写 caption，还会帮你筛数据集。
