[pr-review] Daily PR Code Quality Review — 32814535910 #55678

#55677 — Fix false positives in exitCode check for require-getexecoutput

• pull_request_read (get_diff) and get_files returned no content — PR appears to be an empty/just-opened WIP draft with no committed changes yet.
• No files to review.

#55676 — Update CLI and MCP versions for various tools

• Same as above: no diff/file content returned via MCP tools. WIP draft, nothing to review yet.

#55675 — Fix security findings identified by Sighthound

• Same as above: no diff/file content returned via MCP tools. WIP draft, nothing to review yet.

#55559 — Fix full local Go and JavaScript test suites

• Changes are entirely test-file and shell-script fixes (no new production Go functions added).
• context_cancellation_test.go: replaced a flaky/misleading timing assertion with a deterministic mock (logsFetchWorkflowRunBatch) and proper require.NoError/assert checks — good test hygiene, no bare t.Log-only tests.
• install_copilot_cli_test.go: added a fake sudo shim to avoid real privilege escalation in tests — reasonable, well-scoped.
• scripts/agent-report-progress.sh: added several new shell helper functions (normalize_repo_path, is_changed_go_file, is_linter_summary_line, run_change_scoped_go_linter) — not Go, so doc-comment/error-handling checks don't apply, but functions are reasonably small and single-purpose.
• No oversized functions or missing if err != nil handling observed in the diff.

#55531 — Add read-only GitHub Issues access to agent enclaves

• New file enclave_github_proxy.go: all new functions are unexported (lowercase), so the missing-doc-comment check for exported functions doesn't trigger; still, package-level unexported helpers (buildEnclaveGitHubProxyPolicyJSON, effectivePrimaryGitHubIntegrityFloor, generateStartEnclaveGitHubProxyStep, generateStopEnclaveGitHubProxyStep) lack any comments explaining intent — worth a lightweight comment given the security-sensitive nature (policy/capability generation).
• Error handling looks consistent: json.Marshal errors are wrapped with %w, and step-generation functions propagate errors up through mcp_setup_generator.go.
• All new/changed functions are compact (well under 80 lines).
• 12 new test functions added (TestBuildEnclaveGitHubProxyPolicyJSON, TestEnclaveGitHubProxyVersionGates, etc.) all contain real assertions (not t.Log-only).
• Touches security-relevant surface (capability keys, CA certs, policy JSON) — recommend a focused security/enclave-domain review in addition to this general pass.
