P3 review: the surface, docs and proofs

Split kernel::entry_flows into entry_movements and flows_of so the
reversal-mirror proof fits CI; prove runs the fast harnesses, prove-slow
the 8 slow ones (own job in scheduled CI), prove-all both. Laws in
verification.md renumbered 1-31 with a table of all 55 harnesses.

MCP docs checked against the 115 tools (about 60 fixes) with a test that
every tool is documented; rules.md cross-references fixed; bookspec
statuses and loader tightened; viewer notes wrap and accounts sort by
code; STATUS.md says P3 is built, cutover pending.
