core-refactor: single-reporter telemetry rewrite (#15933)

Browse Source

Overhaul the telemetry system to enforce a single-reporter model where only the HOST sends terminal statuses (success/failed/aborted) to the API. Containers now write local artifact files (.failed flag + .errinfo) that the host picks up after lxc-attach returns, preventing the race condition where a metadata-less container payload would win over the full host payload.

Key changes:
- Add TELEMETRY_CONTEXT=container export in install.func/alpine-install.func to mark container context before error handling starts
- Introduce _is_container_context() heuristic and _container_write_failure() artifact writer in error_handler.func
- Refactor api.func: unified _tm_payload() builder (full metadata on every send), _tm_send() curl wrapper, _tm_enabled() gate, telemetry_collect_sysinfo() cached collector
- Add structured .errinfo capture in silent() (core.func) using byte-offset to extract exactly the failing command's output
- Pull .errinfo from container in build.func after lxc-attach for precise error traces
- Add categorize_error(), telemetry_new_attempt(), detect_arm(), REPO_SLUG tracking
- Signal exits (129/130/143) now report as 'aborted' instead of 'failed'
- Remove post_update_to_api_extended() (superseded by unified _tm_payload)
- Export REPO_SOURCE, REPO_SLUG, TELEMETRY_PLATFORM into container environment
