Cover more constructs in the PDB sequence-point tests

Extends the breakpoint-map comparison to hidden sequence points, anchoring
each hidden point to the visible point it follows so the descriptor stays
independent of the IL offsets the decompiler reconstructs. Adds PdbGen cases
spanning try/catch/finally, switch, async/await, yield, loops, LINQ, pattern
matching and more, pinning the known residuals where the decompiler folds a
compiler-hidden branch into an adjacent point.

Compare PDB sequence points against the compiler's breakpoint map

The PdbGen tests compared the reconstructed PDB to the C# compiler's
byte-for-byte, so any non-trivial method failed on reconstructed IL
ranges, hidden sequence points and local scopes - none of which the
decompiler can reproduce exactly. That left four of seven fixtures
[Ignore]d and the suite with almost no coverage.

Compare only what a debugging user actually feels: the visible (non-hidden)
breakpoint map, parsed straight from the sequence-point blobs and keyed by
method-definition row (shared between the PDB and the PE it describes). IL
offsets, hidden points, local scopes and the embedded source are dropped.
The compiler's own PDB is the oracle, so the tests assert correct debugging
behavior rather than the decompiler's past output. Methods where the
decompiler legitimately diverges pin an auto-derived residual snapshot, the
same accept-the-diff workflow as the pretty tests; a separate oracle-free
check rejects duplicate or overlapping sequence points.

Un-ignores ForLoopTests, LambdaCapturing and Members (its source is
regenerated to match the decompiler's per-type output, collapsing ~50 lines
of indentation-induced coordinate noise to two genuine differences).

Document the decompiler test suite in ICSharpCode.Decompiler.Tests/CLAUDE.md

Captures the compiler-matrix model, the test kinds and their pipelines,
how to add tests per kind, the #if/preprocessor-symbol comparison rules,
and the probe-a-construct-across-all-compilers workflow, so this no
longer has to be reverse-engineered from the runners.
