Docs: point HANDOFF.md at the port's hard rules and fix stale lines (#120)

HANDOFF.md links PC_PORT_PLAN.md section 1 again; the pointers to the plan were dropped from PC.md and
HANDOFF.md in 3e6b4bf and bacee83, which left its hard rules unlinked. Where a rule names specifics
that have since changed, PC.md describes the port as built.

The README no longer calls the port eventual. PC.md names tools/kazarov/src/cpp, where the shared code
lives, instead of tools/kazarov/port. The plan's two "≤" signs, garbled by 50b24b7, are restored.
