v1.2.1 - Phase C Fix3

Changes

Fixed

• Meta-tool dispatch fixes — inline atomic rewrites replace nested dispatch pattern that caused double-execution in flow replay
• Credential round-trip — DPAPI null-byte stripping and explicit error messages on decrypt failure

Added

• TOTP module — totp_register, totp_register_from_uri, totp_generate, totp_list, totp_delete, hotp_generate. HMAC-based one-time passwords with DPAPI-encrypted secret storage.

Binaries

• workflow_arm64_windows.exe — ARM64 native (5.5 MB)
• workflow_x64_windows.exe — x64 native (6.4 MB)
