[CLI-002] Add Go bridge integration tests

[AdeGneus]

Context

The Go CLI bridge runner exists, but it needs integration coverage against the Python bridge command shape before real bridge-backed commands are expanded.

Scope

• Add bridge integration tests in CLI repo.
• Invoke Python subprocess against a fixture or fake bridge module.
• Assert stdout/stderr separation and JSON parsing.

Non-Goals

• Does not implement new CLI commands.

Technical Specification

Tests should verify bridge.DefaultRunner().Run(ctx, "config-validate") invokes python3 -m ori.cli_bridge config-validate and maps errors deterministically.

Acceptance Criteria

• Bridge command name is passed exactly.
• JSON stdout parses.
• stderr remains separate.
• go test ./... passes.

Tests Required

Test	Verifies
TestBridgeRunnerInvokesPythonModule	Subprocess command shape.
TestBridgeRunnerParsesError	Error mapping.

Additional Test Coverage / Edge Cases

• Verify command arguments preserve ordering and quoting when passed to Python subprocess.
• Verify non-zero bridge exit maps to CLI non-zero exit without swallowing stderr.
• Verify malformed bridge JSON becomes a clear CLI error.
• Verify context cancellation/timeout terminates the subprocess.
• Verify stdout and stderr are kept separate.

Invariants — Do Not Violate

• CLI must delegate runtime-owned behavior through bridge.
