Issue #4390: imported Chinese web-novels showed author either missing (未知) or as an irrelevant metadata blob (e.g. 2024/08/01发表于：是否首发：是字数1023150字116:01).

Key debugging tell: the displayed title was the entire filename including 作者：X (e.g. 【月如无恨月长圆】（1-154）作者：陈西). A real EPUB's dc:title would be just the book name. Full-filename title ⇒ the file went through Readest's TXT→EPUB converter (bookService.ts /\.txt$/ → TxtToEpubConverter), which sets bookTitle = base filename in the no-《》 branch of extractTxtFilenameMetadata. So "EPUB format" books can still be TXT-origin — check src/utils/txt.ts, not foliate-js, when title looks like a filename. (Native Rust EPUB parser #4369 was NOT shipped in 0.11.2.)

Two root causes in src/utils/txt.ts:

extractTxtFilenameMetadata only pulled an author from 《》-wrapped names; 【】 names (the web-novel norm) got no filename author.
Greedy header capture /[【\[]?作者[】\]]?[:：\s]\s*(.+)\r?\n/ grabbed a whole noisy metadata line as the author.

Fix:

parseLabeledAuthor(base) extracts the labeled 作者：X from ANY filename; title stays the full name. Only the labeled form is safe on a full filename — a bracketed/bare fallback would mistake a leading 【title】 for the author.
isPlausibleAuthorName() rejects a header match that looks like a blob (contains :/：, a \d{4,} run, or length > 20) → falls back to the filename author. Applied in BOTH convertSmallFile and extractAuthorAndLanguage (large-file path).

Note: the 著 form is handled for file content headers but NOT for filenames (kept minimal). Reported files were 455 kB / 1.25 MB → both under the 8 MB LARGE_TXT_THRESHOLD_BYTES (convertSmallFile path). Tests live in txt-converter.test.ts (faithful repro of both reported strings).
