…w() and tasklet.raise_exception()

Adapt a test case to the new behavior of tasklet.raise_exception(exc_class, *args). Now it raises RuntimeError on errors.

…d tasklet.raise_exception()

Adapt a test case to the new behavior of tasklet.raise_exception(exc_class, *args). Now it raises RuntimeError on errors.

Delete the pending_b2_blocks_ Class B vector + struct PendingBlock +
drain loop in translate(). The W26-era refactor of emitInlineExceptionMatch
removed all writers but left the queue declaration + drain plumbing as
load-bearing-looking dead state.

Independent grep verification (theologian 23:35:58Z + librarian
23:50:24Z + spec §2.1 grep-writers-before-Step-A discipline per pythia
python#93): 4 reference sites, ZERO writers. Mutation patterns
push_back/emplace_back/insert/operator[]/resize/assign/reserve all
NOT FOUND across cpython/. PendingBlock struct unused outside the
deleted field.

Reframes Phase 3 spec §2 inventory: pending_b2_blocks_ marked DELETED
in §2.1 errata; the §5 forcing-decision propagation validation is
now deferred to Batch 4 (block_map_, the next Class B candidate)
with mandatory pre-Step-A writer-grep per spec §2.1 amendment.

NO new bridges, NO new W45 fixtures (delete-of-dead-state per shepard
22:46:33Z + supervisor 23:36:13Z carve-out). NOT counted toward
W45 §3.5 5-batch backstop per supervisor 23:49:22Z (current count
holds at 4: python#6+python#7 fold-into-C + Phase 3 Batch 1+2).

Numstat (vs HEAD 1343895):
  Python/jit/hir/builder.cpp           +0  -6   (drain loop + clear)
  Python/jit/hir/builder.h             +0  -8   (struct + vector field)
  Python/jit/hir/builder_state_c.h     +4  -3   (Class B doc-list refresh
                                                  + dead-state footnote)
TOTAL: NET -13L pure deletion (forecast -15L; -2L variance).

Pre-commit compile-check: testkeeper 23:52:59Z BUILD_EXIT=0,
3-test sanity green (partial_conversions + W22 + W44).

W44 gate: PASS (2 markers, 0 production callers).

Authorization: theologian 23:35:58Z + supervisor 23:36:13Z (A)
DEAD-DELETE only (split from getSimpleExceptInfo per theologian
different-shape-bisect-granularity reasoning).
