rgit context dialled a language server per changed file (vtsls and marksman spawn fresh per call), costing ~0.5-1.8s per call in larger repos; it now skips the LSP cross-check (diff.Options.SkipCrossCheck). rgit diff and rgit commit still verify. context no longer prints W ts-only or cross-check mismatch lines (help, USAGE, CODES, CHANGELOG updated). Measured on a mortar-size clone with 10 edited files, 5 runs: median 568 ms -> 234 ms. gopls -listen.timeout 10m -> 2h: its daemon reload cost ~80s CPU after every 10 idle minutes and the 2s query deadline expired during it. The shared gopls socket was checked and does not mix workspaces (each connection announces its own root). Also: SECURITY.md reporting/disclosure/timeline text. Tests: a live mock LSP socket proves context makes zero connections while diff does. Gate green.
