- Strengthened scratchpad bounds validation and ensured pointer range checks.
- Improved memory management with fallback allocation and robust cleanup.
- Adjusted SEADER_UART_RX_BUF_SIZE to 300 for better headroom.
- Added safeguards against frame/header underflows in scratchpad handling.
- Ensured proper alignment for UART worker and zero-copy transmission paths.
- Strip unused XER, PER, and OER codec support via persistent skeleton gating.
- Refactor high-frequency ASN.1 logic to use stack allocation.
- Implement zero-copy transmission path using 32-byte header offset in UART TX buffer.
- Correct CCID header initialization and DER encoding buffer size calculation.
- Add ASN_DISABLE_* macros to application.fam for consistent gating across builds.
