fix: correcting non-deterministic unit test

  The TestAcceptance_SelfCanary test was failing non-deterministically because it depended on whether GAP_ANALYSIS.md existed in the repo root:

  Root Cause:
  - If the file existed (which it did), it used that file with incorrect requirement IDs (CBIN-001, CBIN-002)
  - If the file didn't exist, it would create one with correct IDs (CBIN-101, CBIN-102)
  - The actual CANARY tokens in tools/canary/ are CBIN-101, CBIN-102, CBIN-103
  - This mismatch caused the verify step to fail

  The Fix:
  1. Created a dedicated testdata directory (tools/canary/testdata/selfcanary/)
  2. Always write the GAP_ANALYSIS.md file with the correct requirement IDs
  3. Use isolated output files in the testdata directory
  4. Made the test independent of the repo root's GAP_ANALYSIS.md file

  Result:
  - Test now passes consistently (5/5 runs successful)
  - All 7 acceptance tests pass
  - Test is now deterministic and isolated from repo state

  The test is fixed in tools/canary/internal/acceptance_test.go:125-157.
