Addresses the partial ports listed in docs/rewrite/notes/review-completeness-codex.md (details in docs/rewrite/notes/gaps-X2.md): - Flatpak: the exit watcher no longer consumes the host command; a shared FlatpakSignalHandle lets closing a surface still SIGHUP the host process group. - Child environment is byte-preserving end to end (ghostty_os::EnvMap of OsStrings) and Snap paths are filtered like filterSnapPaths. - argv handling no longer panics on non-UTF-8 arguments. - URI percent-decoding keeps raw bytes; OSC 7 pwd is passed through without lossy conversion. - Keybinding comparison/hashing uses full Unicode case folding from a table generated from CaseFolding.txt (Unicode 17.0.0). - Link regexes set Oniguruma's whole-search retry limit through the new minimal ghostty-onig crate (one SAFETY-commented FFI call). - OSC 9 NUL-capacity check ordering matches Zig. - Wayland registry binds/clears globals advertised after startup. - Custom shaders may pass sampler2D to helper functions (naga adapter). - +list-themes preview renders OSC 8 links, styled underlines and follows color-scheme reports. Also includes the inspector's integration edits in shared files (renderer state hook, termio VT recording, core/apprt-gtk wiring), X1's config/input/cli additions for completion generation, and a fix for a race in the termio backpressure test (it wrote before `stty raw` applied, so the cooked line discipline dropped bytes past MAX_CANON). Test Plan: - cargo test --workspace - cargo clippy --workspace --all-targets -- -D warnings
