Add Windows support and CI (#7)

* Add Windows support via interprocess crate

- Replace Unix domain sockets with interprocess local sockets (Unix
  sockets on Unix, named pipes on Windows)
- Add process.rs module for cross-platform process management
- Move nix crate to Unix-only, add windows-sys for Windows
- Update force_stop() to use platform-specific termination
- Document Windows limitation: no graceful shutdown (immediate kill)

* Add comprehensive test coverage for identified gaps

- Add 9 tests for ErrorContextBuffer (circular eviction, cloning, timestamps)
- Add 4 process termination tests (SIGTERM→SIGKILL escalation, Windows)
- Add 8 integration tests (panic recovery, large output, stale cleanup, stress)
- Add 2 version tests (mismatch detection, protocol behavior)
- Add Debug derive to TerminateResult for better test output

Total test count increased from ~30 to 57 tests.

* Fix clippy warnings and formatting issues

- Fix collapsible if statement in client.rs
- Use inspect_err instead of map_err in client.rs
- Use assert! instead of assert_eq! with bool literal

- Use .first() instead of .get(0)
- Fix redundant guards in match statements
- Apply cargo fmt fixes

* Fix unused imports on Windows

Add #[cfg(unix)] to imports only used on Unix:
- bail, Duration, sleep in process.rs
- fs in transport.rs

* Fix graceful timeout skipped when < 100ms

Use ceiling division so any positive timeout performs at least one
iteration before escalating to SIGKILL.

* Remove redundant INVALID_HANDLE_VALUE checks on Windows

OpenProcess returns null on failure, not INVALID_HANDLE_VALUE.

* Add owner-only security descriptor for Windows named pipes

Apply SDDL security descriptor D:P(A;;GA;;;OW) to restrict pipe access
to the owner only, equivalent to Unix 0o600 socket permissions.

* Fix Windows process_exists to check actual process status

Use GetExitCodeProcess to verify process is still running, not just
that OpenProcess succeeds. Fixes test_terminate_spawned_process_windows
which was failing because OpenProcess can succeed on terminated
processes during kernel cleanup.

Also fix clippy warning by using div_ceil().

* Complete test_multiple_commands_same_connection test

Actually send a second command and verify the connection is closed,
confirming the server's one-shot semantics.
