actop 1.7.2

Added

• Alert/throttle/energy in export backends (--json / --serve). Both
  run_json_stream and serve_prometheus now construct an AlertEngine from
  the same alert-threshold CLI flags the TUI uses; each snapshot is fed through
  the engine and the resulting AlertFrame (thermal, cpu/gpu throttle, bandwidth
  saturation, package-power peak, swap rise, cumulative session energy) is merged
  into every NDJSON record and every Prometheus scrape. An LLM profiling session
  through --json now answers did the chip throttle? and what did the run
  cost in total energy? without opening the TUI.
• --json-processes / --serve-processes CLI flags for explicit per-process
  rows in export mode. The underlying include_processes pipe already existed;
  these flags close the discoverability gap.

Changed

• Tests restructured to functional-only. Removed 8 format-contract tests
  (single-line JSON, TYPE header present, synthetic AlertFrame key assertions);
  merged fan/process tests; added 2 functional AlertEngine pipeline tests
  (mock Monitor → AlertEngine → verify computed alert values match sustain
  logic). 12 tests now (6 non-local, 6 local), all functional.
• Dropped LC-4 (rolling-stats widget cleanup) from roadmap. 4 deques in
  HardwareDashboard are pure code hygiene, not a user-visible defect, and
  track E does not depend on them.
• CLAUDE.md: added format-contract/shape-test rejection rule to the
  functional-only mandate.
