test(05-02): add GC integration test covering stale removal, valid preservation, empty-dir safety
- Test 1: stale instance dir (project root gone) is removed - Test 2: valid instance dir (project root exists) is preserved - Test 3: empty projects/ dir produces GC complete: 0 instance(s) removed. - Inline gc_instances definition for isolated testing (sed not in PATH) - Canary check verifies gc_instances exists in claudebox.sh

# test-gc.sh — integration tests for gc_instances function (05-02)
|
||||
#
|
||||
# Tests three behaviors:
|
||||
# 1. Stale instance dir (project root gone) is removed
|
||||
# 2. Valid instance dir (project root exists) is preserved
|
||||
# 3. Empty projects/ dir produces "GC complete: 0 instance(s) removed."
|
||||
#
|
||||
# Usage: bash test-gc.sh
