* fix(shell-ready): honor ZDOTDIR without breaking zsh scoping
Fixes#1866
This reimplements PR #1737 (reverted in #1864) with a safer approach
that preserves normal zsh startup semantics.
**Core fix**: Discover ZDOTDIR by sourcing user ~/.zshenv in a subshell
instead of inside a wrapper function. This preserves top-level zsh
scoping for common patterns like `typeset -U path` that broke in the
original implementation.
**Shell safety improvements**:
- Use `printf '%s\n'` instead of `echo` for capturing ZDOTDIR (handles
special characters in paths safely)
- Subshell isolates early returns and side effects from wrapper
**Code quality**:
- Extract duplicated zsh wrapper template to `src/main/shell-templates.ts`
- Both local-pty and daemon paths now share identical wrapper logic
**Test coverage**:
- Add live zsh subprocess tests that spawn real zsh to verify:
- XDG ZDOTDIR discovery works
- `typeset -U path` in .zshrc preserves top-level scoping
- Early returns in .zshenv don't crash the wrapper
- Vanilla (non-XDG) configs fall back to HOME correctly
- Template structure tests validate subshell discovery logic
Before (broken):
```zsh
__orca_source_user_zshenv() {
source "$HOME/.zshenv" # typeset becomes function-scoped
}
```
After (fixed):
```zsh
_orca_discovered_zdotdir=$(
unset ZDOTDIR
[[ -f "$HOME/.zshenv" ]] && source "$HOME/.zshenv" 2>/dev/null
printf '%s\n' "${ZDOTDIR}"
)
export ORCA_ORIG_ZDOTDIR="${_orca_discovered_zdotdir:-${_orca_spawn_orig_zdotdir:-$HOME}}"
```
The subshell sources .zshenv at top-level (preserving normal scoping),
captures only the ZDOTDIR value, then exits. User rcfiles (.zshrc, etc.)
are still sourced at the wrapper's top level, so all scoping works normally.

* Add shell-script-literal test framework and improvements
Adds a new declarative test framework for shell-ready tests that uses
literal shell scripts (copy-pastable into terminals) with inline snapshots.
Framework features:
- Shell scripts as string literals with # Run: marker to split setup/test
- Direct script execution (no brittle parsing) via temp files
- Path normalization for reproducible snapshots (<HOME>, <WRAPPER_DIR>)
- Auto-detects shell from command, supports bash/zsh/sh
- Inline snapshot testing with vitest toMatchInlineSnapshot()
Code quality improvements:
- Extract escapeRegex to shared string-utils.ts (deduplicates 2 copies)
- Refactor shell-templates.ts for readability (condense comments, add structure)
- Pre-compile regex patterns to avoid hot-path allocation
- Fix path normalization to sort by length (prevent nested path corruption)
- Fix actualUserHome handling to skip empty values
All tests passing (64/64 shell-ready tests, 55/55 affected tests).
Files added:
- src/main/providers/__tests__/shell-ready-framework/shell-script-test.ts
- src/main/providers/__tests__/shell-ready-framework/README.md
- src/main/providers/__tests__/shell-ready-framework-example.test.ts
- src/shared/string-utils.ts
Files modified:
- src/main/shell-templates.ts (readability cleanup)
- src/main/codex/config-toml-trust.ts (use shared escapeRegex)
- src/main/daemon/shell-ready.test.ts (updated for new framework)
- src/main/providers/local-pty-shell-ready.test.ts (updated for new framework)
