bflatasticandClaude Opus 5.5 49e8413ebe Fix #130: installed fonts are found by name whatever ran before ...

Opening, placing, pasting or importing a file, the font menus and MCP now find
the installed system fonts (Arial, Times New Roman...) in a fresh session, so a
file renders the same whatever happened earlier, and PDF import keeps the real
family names (Microsoft YaHei, not "Microsoft Ya Hei").

Root cause: FontDb only consulted the system font catalog, which stayed empty
until a CJK fallback or Character panel > Show System Fonts happened to scan
the font folders. Every lookup by family name (face, families, styles,
has_family) now waits for one cataloging scan per session: the app starts it
in the background, other processes run it on first use. The scan reads only
each file's table directory and name table (about 70 ms for 780 faces here,
instead of reading every font file whole), the catalog is indexed by family,
the family list is cached, and an installed style of a loaded family (a
bundled family also installed with more weights) loads when asked for.
