The worker-isolation fix is already in post-FTS master. This PR now adds regression tests only; it changes no production code.

f4789c59f gives each processor run its own decoder and encoder for both ordinary and windowed processing. The former shutdown prerequisites are also in master (543c66491, bbb69cb57), so the rebase drops all three superseded production/test-fix commits.

The remaining 12 integration cases check input/output processor placement, ordinary/threaded HTTP inputs, native and mixed chains, and filter boundaries. Four input workers, four workers on each of two output routes, eight clients, and 32 requests of 128 uniquely identified records exercise record isolation and per-stage counters.

Validation on master 05048e35d with these tests:

• 12 cases pass normally and under strict Valgrind.
• Every selected Memcheck process reports zero errors and zero definite/indirect/possible leaked bytes.
• Full rebased PR commit range passes the repository prefix linter.
• Stress tests and Memcheck do not constitute a race-detector proof.

From the repository root, with FLUENT_BIT_BINARY pointing at the branch build:

python -m pytest tests/integration/scenarios/processor_concurrency -q
VALGRIND=1 VALGRIND_STRICT=1 python -m pytest tests/integration/scenarios/processor_concurrency -q

No configuration or bundled-library changes. Target: master.
