chore(release): v0.4.1 - CI fixes, security updates & dependency refresh

Fix all GitHub Actions CI failures from the v0.4.0 release:

Security:
- Update bytes 1.10.1 -> 1.11.1 fixing RUSTSEC-2026-0007 (CVE-2026-25541):
  integer overflow in BytesMut::reserve causing out-of-bounds memory access
- Add RUSTSEC-2026-0009 (CVE-2026-25727, time crate DoS via stack exhaustion)
  to security audit ignore list -- time pinned at =0.3.45 by mac-notification-sys
  (transitive via notify-rust 4.12.0); requires upstream release to unpin

CI/CD:
- Fix Windows DCC test failure (test_send_and_receive_file): on Windows, TCP
  sends RST instead of FIN when sender drops connection with unread ACK data
  in receive buffer, causing receive_file() to fail with "connection reset"
  instead of clean EOF. Added #[cfg(not(windows))] -- test runs on Linux/macOS
- Update security audit advisory ignore lists in security-audit.yml defaults,
  fallback, and comments, plus master-pipeline.yml workflow_call input
- Change security audit schedule from daily (0 0 * * *) to weekly on Mondays
  (0 0 * * 1) to reduce unnecessary CI resource consumption

Version bump:
- All 7 Cargo.toml files: 0.4.0 -> 0.4.1
- README.md: version badges, release links, status section, added v0.4.1 notes
- CHANGELOG.md: added v0.4.1 entry with Fixed/Changed/Dependencies sections
- CLAUDE.md: updated development status header and added v0.4.1 line item

Dependencies (Cargo.lock refresh):
- bytes: 1.10.1 -> 1.11.1 (security fix)
- Multiple transitive dependency updates from crates.io index refresh

Verification: 266 tests passing, zero clippy warnings, zero fmt issues
