- `--jobs auto` / `-j auto` caps parallel concurrency at the CPU core count (portable across Linux/macOS/BSD); the default stays unlimited (#766)

### Changed
- Faster test runs: listing all defined functions uses the `compgen -A function` builtin instead of forking `declare -F | awk` (three call sites; 5 -> 3 `awk` forks per test file). No behaviour change
- Faster test runs: ordering a file's test functions by definition line is pure bash now instead of an `awk | sort | awk` pipeline that ran twice per file, and the duplicate-function check sorts its (usually empty) result inside awk instead of piping through `sort` (9 -> 5 forks per test file). No behaviour change
- Faster failure rendering: the "Source:" assert-line context of a failing test reads the test-function body in a single pass instead of forking `sed` per line and `grep` per line to find the closing brace (a 20-line body dropped from ~46 to ~2 forks here). No behaviour change
- Faster test runs: each test's subshell result payload is emitted with `printf` (a builtin) instead of a `cat <<EOF` heredoc, removing one `cat` fork per test. No behaviour change

- `--jobs auto` / `-j auto` caps parallel concurrency at the CPU core count (portable across Linux/macOS/BSD); the default stays unlimited (#766)

### Changed
- Faster test runs: listing all defined functions uses the `compgen -A function` builtin instead of forking `declare -F | awk` (three call sites; 5 -> 3 `awk` forks per test file). No behaviour change
- Faster test runs: ordering a file's test functions by definition line is pure bash now instead of an `awk | sort | awk` pipeline that ran twice per file, and the duplicate-function check sorts its (usually empty) result inside awk instead of piping through `sort` (9 -> 5 forks per test file). No behaviour change
- Faster failure rendering: the "Source:" assert-line context of a failing test reads the test-function body in a single pass instead of forking `sed` per line and `grep` per line to find the closing brace (a 20-line body dropped from ~46 to ~2 forks here). No behaviour change
- Faster test runs: each test's subshell result payload is emitted with `printf` (a builtin) instead of a `cat <<EOF` heredoc, removing one `cat` fork per test. No behaviour change

- `--jobs auto` / `-j auto` caps parallel concurrency at the CPU core count (portable across Linux/macOS/BSD); the default stays unlimited (#766)

### Changed
- Faster test runs: listing all defined functions uses the `compgen -A function` builtin instead of forking `declare -F | awk` (three call sites; 5 -> 3 `awk` forks per test file). No behaviour change
- Faster test runs: ordering a file's test functions by definition line is pure bash now instead of an `awk | sort | awk` pipeline that ran twice per file, and the duplicate-function check sorts its (usually empty) result inside awk instead of piping through `sort` (9 -> 5 forks per test file). No behaviour change
- Faster failure rendering: the "Source:" assert-line context of a failing test reads the test-function body in a single pass instead of forking `sed` per line and `grep` per line to find the closing brace (a 20-line body dropped from ~46 to ~2 forks here). No behaviour change
- Faster test runs: each test's subshell result payload is emitted with `printf` (a builtin) instead of a `cat <<EOF` heredoc, removing one `cat` fork per test. No behaviour change
