feat(latex, symbols): add missing LaTeX2e/amsmath/amssymb commands and \mathscr font#522

Conversation
The symbol table covers unicode-math names but lacks some common commands that unicode-math spells differently or omits: \ldots, \iff, \implies, \impliedby, \land, \lor, \emptyset, the amsmath \dots* family, several amssymb symbols, and spacing commands (\quad, \qquad, \enspace, \thinspace, \thickspace) mapped to their unicode space characters. Also adds the \mathscr font, identical to \mathcal since unicode has a single script alphabet, and enables it in the font config, docs and test file. Glyph values cross-checked against Julia's REPL latex-to-unicode table (stdlib/REPL/src/latex_symbols.jl, MIT), itself derived from W3C's unicode.xml.

Problem
A number of very common LaTeX commands don't render because they have no entry in
symbols.entries: the table covers unicode-math names, but not commands that unicode-math spells differently or omits entirely. Related: #178, #176.Examples that currently render as raw text:
\ldots,\iff,\implies,\land,\lor,\emptyset,\mathscr{F}.Changes
symbols.entries: 29 new entries, kept deliberately to the clearly-standard set (LaTeX2e core, amsmath, amssymb):\ldotsand the amsmath dots family (\dotsb,\dotsc,\dotsi,\dotsm,\dotso)\iff,\implies,\impliedby,\land,\lor,\emptyset,\hbar,\bigcirc\circledS,\circlearrowleft,\circlearrowright,\gvertneqq,\lvertneqq,\nleqslant,\nsubseteqq,\nsupseteqq,\varsubsetneqq,\varsupsetneq\quad,\qquad,\enspace,\thinspace,\thickspacemapped to the corresponding unicode space characters (U+2003 etc.)symbols.fonts: newmathscrtable, identical tomathcalsince Unicode has a single script alphabet (both map to the U+1D49C block plus the Letterlike Symbols exceptions). The existing#lua-match? "^\\math"query already captures it, so only the symbol table, config default, docs andtest/latex.mdneeded touching.Notes
stdlib/REPL/src/latex_symbols.jl, MIT), which is itself derived from W3C'sunicode.xml. No code was taken from it, only the factual command-to-codepoint mapping.\qquadas raw text. Happy to drop them from the PR if you'd rather keep spacing commands unhandled.\hat,\vec,\ddot, ...) were deliberately left out; concealing them to combining characters without reordering would render incorrectly.🤖 Generated with Claude Code
