program_engine: Phases 1+2 — Clock abstraction + TIMED execution

First half of the autonomous program-execution engine. Two phases land
together because Phase 1 was pure scaffolding (Clock + classifier)
and made little sense in isolation.

Phase 1 — engine foundation:

* Clock protocol with RealClock (wall time + asyncio.sleep) and
  FakeClock (manual advance, no real waiting; sleepers wake in
  chronological order on advance_to).
* classify(programs) splits a Program tuple into timed / event /
  yearly / clausal-head buckets, dropping FREE / REMARK / unknown
  records and the AND/OR/THEN clausal continuations (those are
  reached by walking forward from each WHEN/AT/EVERY head, not by
  classification).
* ProgramEngine class with start / stop lifecycle (idempotent +
  context-manager), per-program asyncio task list, _EngineMetrics
  counters.

Phase 2 — TIMED programs actually run:

* _next_absolute_fire(now, program) computes the next datetime at
  which a TIMED program with TimeKind.ABSOLUTE should fire, given
  its hour/minute/days mask. Walks forward up to 8 days; returns
  None for empty Days mask (program is effectively disabled).
* Each TIMED program gets its own asyncio task running
  sleep-until-next-fire / fire / loop. Firing dispatches the
  4-byte Command wire payload (cmd / par / pr2) through
  MockPanel._handle_command — same code path the v2 Command opcode
  uses, so a TIMED program turning on a unit produces identical
  state to a client sending the equivalent Command.
* astral added as an [engine] optional dependency, pinned to 2.2
  for HA compat (HA itself pins astral==2.2). Library wired up but
  not yet consumed — sunrise/sunset support lands in Phase 3.

Tests (28 new):

* RealClock and FakeClock behaviour incl. chronological wake order.
* classify against each ProgramType, unknown values, empty input.
* Engine lifecycle (idempotent start/stop, context manager,
  malformed-record tolerance).
* End-to-end: TIMED UNIT_ON program fires at the right Monday 06:00,
  loops correctly across weeks, never fires outside its Days mask,
  ignores programs with empty Days mask.

Full suite: 527 passed, 1 skipped (up from 499).

"""Autonomous execution engine for HAI Omni panel programs.
The :mod:`omni_pca.mock_panel` module turns ``MockState`` into a
wire-speaking *replay* of a panel: clients ask for properties, names,
programs, and the mock serves what's on disk. The engine in this
module is the next layer it interprets the decoded :class:`Program`
records as **automation rules** and fires them autonomously over time,
mutating ``MockState`` the same way a real panel firmware would.
Architecture
------------
The engine is decoupled from real wall-time via a :class:`Clock`
protocol so tests can fast-forward through schedules without waiting
for real seconds to elapse. Two implementations ship:
* :class:`RealClock` the production engine. ``now()`` returns
``datetime.now()`` and ``sleep_until()`` does ``asyncio.sleep``.
* :class:`FakeClock` for tests. ``now()`` returns the manually-set
current time and ``sleep_until()`` returns immediately after
recording the target. Tests then call ``advance_to(target)`` to
jump the clock forward and let pending sleepers wake up.
Program-type coverage is built up in phases:
* Phase 1 (this module's initial cut) — skeleton + Clock + the
classifier that splits :class:`Program` records into "schedulable
by time", "event-triggered", and "clausal head" categories.
* Phase 2 TIMED program execution.
* Phase 3 YEARLY + sunrise/sunset via :mod:`astral`.
* Phase 4 EVENT program routing.
* Phase 5 full clausal evaluator for firmware-3.0 multi-record
WHEN/AT/EVERY + AND/OR/THEN chains.
The engine never touches the wire directly. All state mutations go
through :meth:`MockPanel._apply_unit_command` (and siblings), which
are the same code paths the v2 ``Command`` opcode handler uses so
"engine fires a TIMED program that turns on unit 5" and "client sends
``Command(UNIT_ON, 5)``" produce identical results.
