Ben SchumacherandClaude Sonnet 4.6 58052db8e3 [MM-67976] Add server uptime to support packet (#35838)
* MM-67976: Add server uptime to support packet

Add process start time (started_at) and approximate host start time
(host_started_at, Linux only, derived from /proc/uptime) to the support
packet diagnostics. This helps diagnose restart loops and distinguish
process restarts from full machine/container reboots.

* Add HostStartedAt assertions to support packet happy-path test

* Revert unrelated changes

* Add unit tests for getHostUptimeSeconds and fix cross-platform portability

- Extract parseUptimeFile helper in uptime_linux.go to enable unit testing
  with synthetic file paths without touching the real /proc/uptime
- Add uptime_linux_test.go covering all error paths (file read error,
  empty file, non-numeric value) and happy-path parsing
- Add uptime_other_test.go asserting the non-Linux stub returns
  ErrHostUptimeUnsupportedPlatform and zero seconds
- Guard HostStartedAt assertions in support_packet_test.go with
  runtime.GOOS so the test correctly asserts zero-time on non-Linux
  platforms instead of failing

* test: use t.TempDir() for guaranteed-missing path in uptime test

Replace the hard-coded /nonexistent/proc/uptime path with a path
constructed from t.TempDir() to guarantee the file is absent without
relying on filesystem layout assumptions. Also remove the misleading
comment about swapping implementations.
