add GFM emphasis and underscore-delimited strong modesThree new inline formatting modes for GitHub Flavored Markdown: GfmEmphasis `*text*` → GfmEmphasisUnderscore `_text_` → (MD-preferred only) GfmStrongUnderscore `__text__` → (MD-preferred only)All three emit the same handler instructions as DokuWiki's Emphasis /Strong, so existing renderers need no changes.Design notes:* Lexer mode names use snake_case (gfm_emphasis, gfm_emphasis_underscore, gfm_strong_underscore) to keep PascalCase readable at the class level. The asterisk variant emits `emphasis_open`/`emphasis_close` via the getInstructionName() hook, so DW's Emphasis (`//...//`) and GfmEmphasis (`*...*`) can coexist in mixed modes without a lexer state collision while still producing the same output.* Underscore variants gate on Markdown-preferred syntax (`markdown`, `md+dw`) because `__` otherwise means DW underline. GfmStrongUnderscore sorts at 70 (matching Strong) — below Underline at 90 — so when loaded it wins the lexer race for `__` runs. Underline is already gated out of MD-preferred modes in the previous commit.* Entry patterns enforce the simplified CommonMark flanking rules already shared across DW inline modes (non-whitespace adjacency, no paragraph-boundary crossing) plus the word-boundary check for underscore variants using NO_WORD_BEFORE / NO_WORD_AFTER. The positive non-word-char enumeration makes them multibyte-safe without requiring the `u` flag: `für_etwas` and `пристаням_стремятся_` correctly stay literal.Per-mode unit tests cover basic matching, single-char bodies,leading/trailing-whitespace rejection, empty-delimiter rejection,paragraph-boundary rejection, multibyte intraword protection, andsort values. ModeRegistryTest's gating data provider picks up thethree new rules. List of files: /dokuwiki/inc/Parsing/ParserMode/GfmEmphasis.php
