Xubin Ren 5badb75f6c review: tighten scope and add regression tests ...

Follow-ups from review of #3194:

- ci.yml: drop unconditional --ignore=tests/channels/test_matrix_channel.py.
  That test file already calls pytest.importorskip("nio") at module top, so
  it self-skips on Windows (where nio isn't installed) without also hiding
  62 tests from Linux CI.

- filesystem.py: hoist `import os` to the module top and drop the duplicate
  inline import in ReadFileTool.execute. Document the CRLF->LF normalization
  as intentional (primarily a Windows UX fix so downstream StrReplace/Grep
  match consistently regardless of where the file was written).

- test_read_enhancements.py: lock down two new behaviors
  * TestFileStateHashFallback: check_read warns when content changes but
    mtime is unchanged (coarse-mtime filesystems on Windows).
  * TestReadFileLineEndingNormalization: ReadFileTool strips CRLF and
    preserves LF-only files untouched.

- test_tool_validation.py: restore list2cmdline/shlex.quote in
  test_exec_head_tail_truncation. The temp_path-based form was correct,
  but dropping the quoting broke on any Windows path containing spaces
  (e.g. C:\Users\John Doe\...). CI runners happen not to have spaces so
  this slipped through.

Tests: 1993 passed locally.
