Subject: [PATCH] fix: remove set -e from agent, guard all commands with ||
 true

- Removed 'set -e' so a failing metric collection command doesn't kill
  the agent process
- Added '|| true' to every command in collect_metrics() to prevent
  pipeline failures
- Fixed push_metrics() to capture curl exit code with 'local code; code=$(...) || code=0'
- The agent now keeps running even if individual metrics or push fail
