Testing with a real user config showed that `target/release/ghostty` and
`target/production/ghostty` (also `cargo run --profile production`, which
the README recommends) silently ran without resources: the configured
theme was not applied, bash shell integration was disabled ("no resources
dir set") so tab titles, the prompt cursor and cwd inheritance for new
tabs/splits broke, and terminfo was missing.
Zig never hits this because `zig build` installs `zig-out/share/ghostty`
next to `zig-out/bin`, which the exe-relative sentinel search finds. Cargo
has no such tree; the Rust-specific fallback to `<workspace>/resources`
was limited to the dev profile. It now applies to every profile. It only
triggers when the exe lives inside the workspace it was built from, after
GHOSTTY_RESOURCES_DIR and the share/ sentinel search, so installed
binaries are unaffected.
Test Plan:
- cargo test -p ghostty-os (dev_fallback_finds_workspace_resources now
covers release builds and env precedence)
- run target/production/ghostty with `theme = Catppuccin Mocha` and
`shell-integration = bash`: theme applied, titles show the cwd
