docs(changelog): add AUTO mode banking app fix to v6.0.0 notes

v6.0 changed bare target.txt entries from AUTO to GENERATE, breaking
apps like BHIM that need TEE-backed attestation keys. Restore AUTO as
default and resolve it at config level (PATCH if TEE works, GENERATE
if not) to bypass the non-deterministic raceTeePatch path.

+### Banking App Compatibility
+- Bare `target.txt` entries now default to AUTO mode, resolved at config level to PATCH (working TEE) or GENERATE (broken TEE)
+- Fixes BHIM and similar banking apps that require TEE-backed attestation keys
+- Restores v5.0 behavior where AUTO was resolved before the interceptor dispatch, avoiding the non-deterministic `raceTeePatch` path

 ### Infrastructure
 - Version scheme changed to semver (v6.0.0)
 - Repository moved to TEESimulator-RS as canonical source
