Tests were failing because they relied on the old default limit of 20,000:
- test_memory.py: "x " * 50000 = 100,000 chars now equals the limit
instead of exceeding it. Increased to "x " * 60000 (120k chars).
- test_block_manager.py: Block created with default limit (now 100k),
then 30k char update no longer exceeds it. Set explicit limit=20000
on the test block to preserve the test intent.
- test_log_context_middleware.py: Removed stale `limit: 20000` from
dummy frontmatter fixtures to match new serialization behavior.

* fix(core): handle git memory label prefix collisions in filesystem view
Prevent context window preview crashes when a block label is both a leaf and a prefix (e.g. system/human and system/human/context) by rendering a node as both file and directory. Add regression test.

* fix(core): parse git-backed core memory in context window preview
ContextWindowCalculator.extract_system_components now detects git-backed memory rendering (<memory_filesystem> and <system/...> tags) when <memory_blocks> wrapper is absent, so core_memory is populated in the context preview. Add regression tests.
