M4.6 follow-up piece 2. `Style` gains `underline_color: Color` (Default = follow the text color) so a diagnostic squiggle can be red/yellow/cyan/gray without clobbering the syntax color of the text it underlines — exactly why error_style() left its 'red' unwired until now. The wire consequence: Style rides inside Cell / CellDelta / Snapshot / StyleSpans, so this is the protocol's first encoding-breaking change. PROTOCOL_VERSION 5 → 6 and SUPPORTED_PROTOCOL_VERSIONS narrows to [6]: postcard is not self-describing, so no per-session send gate can keep a v5 peer decoding v6 cells — a mismatched pair now fails the handshake with a clean VersionMismatch instead of garbling mid-session. Version policy tests rewritten to pin the new contract. Surface wiring: - diag.rs: per-severity underline_color (indexed 1/3/6/8). - frontend.rs: kitty-style CSI 4:N for Double/Curly/Dotted/Dashed (previously flattened to plain SGR 4) + SGR 58:5/58:2 emission. - ansi.rs: parse SGR 58/59 with the 38/48 extended-color grammar. - overlay.rs merge_styles: non-default-wins, like fg/bg/underline. - lua_bindings.rs: underline_color on Lua style tables.
