docs: The Dictionary of v4 -- every live word, alphabetical, its stack notation and description; built and published with every release (#157) [skip ci]

make dictionary -> build/docs/Dictionary.pdf (20 pages): mkdictionary.py checks docs/reference/v4-dictionary.tsv against the booted system's words first, so a stale dictionary fails the build; then Markdown, pandoc, docs/book/dictionary.tex (the books' preamble, its own title page: version and commit). Quoted FORTH tokens set as code, so their quotes print straight. The nightly's docs stage builds it; publish sends classifier dictionary; the Gitea release attaches it.

+\chapter{How to read it}
+Every word of the dictionary StarForth v4 boots with is here, in
+alphabetical order. The names are not typed by hand: they are the booted
+system's own list (\texttt{WORDS}, and the kernel's words of the node), and
+the build refuses a dictionary that has fallen behind it.
+
+\textbf{Stack notation.} \texttt{( before -{}- after )}: the values a word
+takes from the stack, the top on the right, and what it leaves there.
+\texttt{( R: ... )} is the return stack. \texttt{n} a signed number,
+\texttt{u} an unsigned one, \texttt{d} and \texttt{ud} double-cell numbers,
+\texttt{q} a Q48.16 fixed-point number, \texttt{x} any cell, \texttt{flag}
+a truth value (0 false, -1 true), \texttt{c} a character, \texttt{addr} a
+cell address, \texttt{baddr} a byte address, \texttt{xt} an execution token.
+
+\textbf{xxx.} Where a word reads a name or text from the input stream, the
+description shows it, as \texttt{' xxx} or \texttt{.\textquotedbl{} text\textquotedbl}.
