Zig treats paths, arguments and environment values as byte slices; the
port converted them lossily in many places. Now (final-Z1.md):
- argv, env (incl. present non-UTF-8 values), HOME, PATH lookup,
passwd, resources dir, TMPDIR, cgroup, config path canonicalization,
+validate-config, +list-themes and Zig-string escapes (\xFF) keep raw
bytes. String-based config values carry bytes via ghostty_os::osbytes,
a bijective escape (noncharacter U+FDD0 + byte) that leaves all valid
UTF-8 - including Nerd Font private-use icons - unchanged.
- os/file rlimit fallbacks exist on all targets.
- i18n locale canonicalization is an exact port of libintl's tables
(e.g. pa-Guru -> pa_IN).
- New ghostty-build-info crate is the single source of version, channel,
commit and build mode for all consumers.
Test Plan:
- cargo test -p ghostty-os -p ghostty-config -p ghostty-cli
(incl. randomized osbytes round-trip property tests)
