Define built-in highlight groups added in nvim 0.9-0.12 - #47

Conversation
Fills the gaps where modern UI surfaces fell back to nvim's own default colorscheme and clashed with the palette: inlay hints, code lens, deprecated/unnecessary diagnostics, winbar, snippet tabstops, float footers, :substitute preview, terminal cursor, and the popup menu's kind/extra columns with their selected and matched variants, plus ComplHint for the native completion UI. Assignments map each group's default link onto the existing palette (SnippetTabstop→visualbg via Visual, DiagnosticUnnecessary→weakfg via Comment, Substitute=Search, TermCursor=reverse, Pmenu*Sel=PmenuSel). Where the faithful mapping is unreadable on this palette the value deviates deliberately: InlayHint/CodeLens/ComplHint use weakfg because dogrun's NonText (the default link target) sits at 1.36:1 over the background, and PmenuKind/Extra use lightfg as a readable step below the menu text. NormalNC stays undefined (it would restyle inactive windows), and ComplMatchIns stays undefined to honor upstream's deliberate `default link ComplMatchIns NONE` — styling it would repaint buffer text on every completion insert.

Summary
Defines 16 built-in highlight groups introduced across nvim 0.9–0.12 that previously fell back to nvim's default colorscheme and clashed with the palette:
LspInlayHint,LspCodeLens,ComplHint,DiagnosticDeprecated,DiagnosticUnnecessary,WinBar/WinBarNC,SnippetTabstop,FloatFooter,Substitute,TermCursor, and the popup menu'sPmenuKind/PmenuExtracolumns with theirSelvariants plusPmenuMatchSel.All values reuse existing palette colors — no new palette entries, no changes to any existing group. Assignments follow each group's default link semantics (
SnippetTabstop→Visual,DiagnosticUnnecessary→Comment,Substitute=Search,TermCursor=reverse,Pmenu*Sel=PmenuSel) except where the faithful mapping is unreadable on this palette: inlay hints / code lens / completion hints useweakfg(Comment-toned, 2.4:1) because the default link target NonText maps todarkfgat 1.36:1 here, andPmenuKind/PmenuExtrauselightfgas a readable step below the menu text.Deliberately left undefined:
NormalNC— defining it would restyle inactive windows.ComplMatchIns— upstream deliberately shipsdefault link ComplMatchIns NONE; styling it would repaint buffer text on every completion insert.All 16 names verified to exist as built-in groups on nvim 0.12.3 (
hlexists), and the generated diff is 16 added lines with zero changes to existing output.Test plan
