Bring apps/desktop and ui-tui to a clean state for typecheck, eslint,
and prettier:
- Run prettier across both trees (printWidth/wrap drift; prettier is not
CI-enforced for these JS projects, so main had accumulated drift).
- Apply eslint --fix for padding-line-between-statements and perfectionist
import/export sorting.
- Manual fixes for non-auto-fixable rules:
- remove unused node:net import in electron/main.cjs (uses Electron net)
- replace inline `typeof import(...)` annotations with top-level
`import type * as EnvModule` in two ui-tui test files
- scoped eslint-disable no-control-regex on intentional sentinel/ANSI
regexes (mathUnicode.ts, text.ts)
- resolve react-hooks/exhaustive-deps per-case: correct swapped/missing
deps, collapse redundant session.* members, and justified disables on
settings mount-only data-load effects to preserve run-once behavior
No behavior changes; test pass/fail counts are unchanged from the main
baseline.
macOS Desktop backend processes can still miss Apple Silicon Homebrew paths even after adding Hermes-managed Node and venv bins. That leaves `/codex-runtime on` unable to find a Homebrew-installed `codex` binary at `/opt/homebrew/bin/codex`.
Add a small testable backend env helper that builds the dashboard subprocess environment in one place. It prepends Hermes-managed Node and venv bins, appends missing POSIX sane PATH entries individually, preserves caller precedence without duplicates, and keeps Windows PATH casing/delimiters intact.
Wire both source-checkout and active-install backend descriptors through the helper, and add Node regression coverage to the desktop platform test suite.
