fix(#2366): scope parseCoverageMatrix to recognized coverage tables (#2551)

Browse Source 
* test(#2366): regression tests for parseCoverageMatrix scoping bugs

Bug 1: summary table outside matrix not parsed as data
Bug 2: multi-section matrix with repeated headers parses correctly
Bug 3: markdown emphasis on decision cell is stripped

* fix(#2366): scope parseCoverageMatrix to recognized coverage tables

Replace latching sawHeader with contextual inMatrix tracking that
resets on non-pipe lines, preventing summary tables from being parsed
as data (bug 1). Allow multiple headers for multi-section matrices
(bug 2). Strip markdown emphasis from decision cells before validation
(bug 3).

Closes #2366

* fix(#2366): update representative-corpus test to expect correct behavior

The test previously documented the known-buggy parseCoverageMatrix behavior.
Now that the fix is in place, test against the expected correct output
(expectedBlock, expectedCounts, expectedErrorCount) instead of the
currentBuggyOutput snapshot.

**`parseCoverageMatrix` now scopes table parsing to recognized coverage matrices** — pipe-tables outside the matrix (e.g., summary tables) are ignored instead of being silently parsed as data rows, multi-section matrices with repeated headers are supported, and inline markdown emphasis (`**OPT-OUT**`) on decision cells is stripped before validation. Previously, the parser scanned every `|`-prefixed line file-wide with a latching header flag, causing silent phantom-capability corruption from unrelated tables, false rejection of multi-section matrices, and rejection of bold-emphasized decisions.
