Fix generic boolean status report projection

[masarray]

Problem

ARSAS event logs can receive a full CDC structure for generic SPS-style status objects, for example:

Structure(3) {stVal=false, q=Quality{...}, t=BinaryTime(...)}

instead of the scalar stVal leaf. The report projector already handles known structures such as Pos, Op, Str, and phase measurements, but generic Boolean status structures fall through to the raw-structure renderer.

Fix

• Project the bounded SPS-style shape { Boolean stVal, Quality q [, Timestamp t] } to <reference>.stVal.
• Preserve quality and timestamp on the projected update.
• Mark the projection as projected-boolean-status.
• Keep the rule intentionally narrow so non-Boolean structures such as {mag,q,t} are not misclassified.

Regression coverage

• Reproduces the INVERTERA2/LLN0.ACAlm1 shape from the ARSAS field event log.
• Verifies false, good, timestamp, and projected .stVal reference.
• Negative test confirms a non-Boolean three-field structure remains raw and emits REPORT_RAW_STRUCT.

This is the source-of-truth engine fix; ARSAS also has a compatibility guard PR for installations still pinned to an older engine commit.
