Add iteration API for sections and keys

[Copilot]

• Diagnose CI failure root cause: DMOD develop branch added new BUILTIN API functions (_SetModuleLogLevel, _GetModuleContext, _GetModuleLogLevel) on 2026-03-06 that are absent in the dmod:1.0.4 docker image, causing unresolvable output entries in modules compiled with the newer headers
• Pin GIT_TAG in CMakeLists.txt to DMOD commit 69a8f744 (2026-03-01) — last commit compatible with dmod:1.0.4
• Verify the fix resolves CI

@copilot CI failuje:

The CI failure was caused by the DMOD develop branch, not the dmini code. On 2026-03-06, the DMOD library added three new built-in API functions (_SetModuleLogLevel, _GetModuleContext, _GetModuleLogLevel) that are absent from the dmod:1.0.4 docker image used in CI. Modules compiled against the newer headers have unresolvable output entries at runtime, so IsAllApiConnected fails.

Fixed in commit aecbe7d by pinning GIT_TAG in CMakeLists.txt to 69a8f7446a377751d6e1d5be33ba77521eda84cc — the last DMOD commit known to be compatible with dmod:1.0.4 (confirmed by the passing main-branch CI run on that date).
