Genre filtering silently returns unfiltered results

The novel-finder endpoint expects numeric genre ids in gi. The plugin
sends slugs, which the server ignores — so filtering by genre returns the
full listing, which reads as "the filter does nothing". This is the
behaviour reported in #2510.

Measured against the live endpoint:

query	results
(no filter)	94754
gi=action&gc=and — what the plugin sends today	94754 — ignored
gi=1&gc=and	66647 — applied
ti=417&tc=and	77061 — tags already worked
ti=417,20&tc=and	407 — comma-joined ids work

So gi, gc, the exclusion params and comma-joining were all correct
already; only the values were wrong. That also explains why tag filtering
worked and genre filtering didn't — the tag options were already numeric
ids.

The mapping

Genre ids are the 1-based alphabetical positions of the option list
already in the plugin. 32 of the 40 were read directly from the genre
chip links the site renders on novel pages (/en/novel-list?genre=<id>).
The remaining 8 — Ecchi, Erciyuan, Mecha, Shoujo, Smut, Sports, Tragedy,
Wuxia — were each verified individually: filter by the id, open a novel
from the results, confirm the rendered name matches and that the novel
carries that id in serie_data.genres. All 40 check out.

Tag options are already numeric ids and are untouched.

Scope

One change plus the version bump — 1.2.1 → 1.2.2. Nothing else in the
file is modified; the chapter-title heading from #2538 and the
translation-mode work from #2525 are left exactly as they are.

Confidence Score: 4/5

The PR should not merge as the filtering fix will not reach users.

Findings

1.  Genre fix will not ship ▶

Summary

The PR adds a root-level copy of WTR-LAB with numeric genre filter values and a version bump, rather than updating the existing plugin.

• The production build excludes the added file, leaving the intended filtering fix unpublished.

Genre fix will not ship

This adds the new genre values and version bump to a root-level file, but the production build excludes root-level files and discovers plugins under plugins/english/. The existing plugins/english/wtrlab.ts still uses version 1.2.1 and slug-valued genres. As a result, users will continue to receive the old plugin and genre filtering will remain broken. Apply the change to the existing plugin file.
