The E2E Package.swift declared swift-tools-version 5.7 and a macOS v12
platform, but the SDK root Package.swift requires macOS v14 (raised from
v13 to v14 in 8.0.0, commit 6218165). This mismatch broke
`xcodebuild build-for-testing` for the e2e target:

  error: The package product 'EdgeAgent' requires minimum platform
  version 14.0 for the macOS platform, but this target supports 13.0
  (in target 'e2e-tests' from project 'e2e')

And with the lower swift-tools-version, `.macOS(.v14)` is itself
unavailable (it requires swift-tools 5.9+, which introduced the v14
platform).

Bump swift-tools-version to 5.9 and raise the E2E macOS platform to v14
so the test target builds against the 8.x SDK.

Introduce decoupled liveness and readiness probe endpoints to improve stability and traffic routing in orchestrated environments like Kubernetes.

- Add GET /health for a lightweight HTTP-server-only liveness check.
- Add GET /healthz for node connectivity readiness, backed by a background poller.
- Add configuration for background health check interval.
- Fix nil pointer risk in submit witnesses parsing and style issues.
- Update documentation in README.md.

BREAKING CHANGE: The /healthcheck endpoint has been completely removed and replaced with /health and /healthz. Any external health checks/probes targeting /healthcheck will receive a 404 and must be updated.
