orchestrator: Compose boot-walk supervision from the board's BootWatch capability

ReleaseReset arms the component's walk, AssertReset stops it, and the
new PlatformDriver::poll_boot_walks maps terminal verdicts to events:
Complete becomes ComponentReady (Active) or Booted (Passive), Failed
becomes Timeout regardless of cause — retry budgeting is the SM's. A
finished walk stops being watched, so each verdict is delivered once;
while everything waits, the poll carries the earliest walk deadline as
the run loop's next wake-up.

BootWatch gains arm(): a retry re-release starts a fresh walk, and
since reset actuation has no clock, the attempt starts at the next
poll's now_millis. The Board supplies one walk and one ComponentKind
per component, from the same table as the SM's chain.

The driver README still described take_event and NotImplemented, both
gone; rewritten to the current execute/fail-closed shape.
