[BUG] BATS detect_editor_cli 'neither cursor nor code' test is host-dependent

[c-vigo]

Description

The BATS test for detect_editor_cli assumes PATH=\"/usr/bin:/bin\" contains neither cursor nor code, but on some hosts /usr/bin/code exists. This makes the test fail for environment reasons rather than script logic.

Steps to Reproduce

1. Check out branch feature/70-remote-devc-orchestration.
2. Run just build no_cache.
3. Run just check.
4. Observe failure in tests/bats/devc-remote.bats for:
   • detect_editor_cli fails when neither cursor nor code in PATH

Expected Behavior

The test should deterministically validate the "neither editor CLI found" path, independent of host-installed binaries.

Actual Behavior

On environments where code exists in /usr/bin, detect_editor_cli selects code and execution proceeds to SSH checks. The assertion expecting Neither cursor nor code fails.

Environment

• OS: Linux 6.17.0-14-generic
• Container Runtime: N/A (failure occurs before remote runtime checks)
• Image Version/Tag: N/A
• Architecture: AMD64

Additional Context

Observed output snippet:

• ℹ Detecting local editor CLI...
• ✓ Using code
• ℹ Checking SSH connectivity to myserver...
• ✗ Cannot connect to myserver. Check your SSH config and network.

Likely fix: isolate PATH in the test with an empty temp directory and invoke /bin/bash "$DEVC_REMOTE" under env -i to keep shebang behavior deterministic.

Possible Solution

Update the failing test setup to avoid /usr/bin:/bin assumptions and use a controlled PATH with no cursor/code binaries.

Acceptance Criteria

• Reproduced on host with /usr/bin/code
• Test updated to be environment-independent
• tests/bats/devc-remote.bats passes locally and in CI
• TDD compliance (see .cursor/rules/tdd.mdc)
