[ddtdanilo-lmdb-wrapper] Add new port

[ddtdanilo]

Summary

Add new port ddtdanilo-lmdb-wrapper version 1.0.1.

ddtdanilo-lmdb-wrapper is a MISRA C compliant wrapper for LMDB (Lightning Memory-Mapped Database). It provides a safe, validated API layer over LMDB with:

• Full parameter validation on every function call (null checks, invalid value checks)
• Explicit error codes for all failure modes
• All return values validated (no unchecked calls)
• Read API copies values into caller-owned buffers (no dangling pointers)
• Single return point per function
• C99, no goto, no dynamic allocation without validation

Use Cases

LMDB is used in production by major projects (Monero, OpenLDAP, Postfix, Caffe). This wrapper adds the MISRA C safety layer required for regulated environments:

• Blockchain & cryptocurrency — zero-copy reads and lock-free concurrent readers make LMDB ideal for distributed ledger systems
• Automotive (AUTOSAR, ISO 26262) — functional safety requires MISRA C compliance
• Medical devices (IEC 62304) — regulatory compliance demands validated, traceable code
• Industrial control (IEC 61508) — safety instrumented systems require defensive programming
• Aerospace (DO-178C) — airborne software requires strict coding standards
• IoT & firmware — persistent config and state on constrained devices; LMDB's ~30KB footprint fits embedded targets

Updated to v1.0.1. Changes from 1.0.0:

• Redesigned lmdbWrapperGet API: the function now copies values into a caller-provided buffer (void *valBuf, size_t valCapacity) instead of returning a pointer to LMDB's internal memory-mapped data. This eliminates dangling pointer risks and gives callers clear ownership of the data.
• Added LMDB_WRAPPER_ERR_BUFFER_TOO_SMALL error code for when the caller buffer is insufficient (the required size is still returned via valSizeOut).
• Supports size-only queries by passing valBuf=NULL, valCapacity=0.
• Added cppcheck static analysis step to CI.
• Added AGENTS.md for Codex compatibility.

All existing platforms passed on v1.0.0; waiting for v1.0.1 CI results now.

Since this is a new port, the version file should only contain one entry

Googling this project surfaces a different project.

To disambiguate this port from other projects, I ask we change the name to ddtdanilo-lmdb-wrapper

Thanks for the review @JavierMatosD! Done:

• Renamed port to ddtdanilo-lmdb-wrapper
• Version file (versions/d-/ddtdanilo-lmdb-wrapper.json) now has a single entry
• Removed old versions/l-/lmdb-wrapper.json
• Updated baseline.json accordingly
