ci: Fix macOS tests and add FreeBSD support (#3442)

* ci: Remove failing macos-13 from test matrix

* ci: Add FreeBSD testing workflow

* ci: Document test matrix rationale

* ci: Update cross-platform-actions to v0.32.0 for FreeBSD 14.2 support

* ci: Use FreeBSD 14.1 (14.2 has SSH connectivity issues)

* ci: Switch to vmactions/freebsd-vm for FreeBSD testing

* ci: Fix FreeBSD package names (pip included in Python)

* ci: Simplify FreeBSD matrix and fix package names

* ci: Use specific Python version command on FreeBSD

* ci: Add sqlite3 package for FreeBSD

* tests: Increase signal integration test timeouts for CI

The signal integration tests were flaky in CI environments,
especially FreeBSD VMs, due to 10-second timeouts being too short.
Increased timeouts to 30 seconds to handle slower CI environments.
