- valid_html_tags: HTML export now passes the allowlisted inline tags through
verbatim (b/i/sub/sup/kbd/div/center/strong/em/...) and escapes the rest,
via a render-time tag-aware escaper (write_escaped_allowing/match_allowed_tag)
— mirroring upstream's s:safe_html_line regex rather than a parser change.
`span` is always allowed so colour spans render.
- emoji_enable: render-time `:alias:` -> glyph substitution (curated common
set), default on; with_emoji builder + substitute_emoji/emoji_for.
- color_tag_template: :VimwikiColorize now wraps via a configurable template
(g:nuwiki_color_tag_template / setup color_tag_template), splitting on
__CONTENT__ with __COLORFG__ -> colour; both clients. Colour spans render in
export via the valid_html_tags span passthrough. Default template reproduces
the prior `<span style="color:NAME">` output (harness colorize tests green).
Renderer gets with_valid_html_tags + with_emoji; export.rs wires both from
HtmlConfig. Tests: valid_html_tags passthrough + escape, emoji on/off
(html_export.rs). Full rust suite + both harnesses green (Neovim 307,
Vim 301/18/21); clippy clean.
