Transaction Science 2778ddd525 wai-quantum: the planner under a contract, its reasoning sealed, a provider's answer shadowed
Re-landed from PR #668 (branch wai/quantum-planner-contract, merged with main
495651ddd at 37350335b) as one commit on main, under the land-it model. Five
review rounds; round 5's findings (two high: workers that died as PID 1) were
fixed on the branch, and its CI reds were traced and fixed before landing.

A job may carry a contract (deadline, energy ceiling, cost, accuracy); the
planner chooses a route that meets it or refuses with every route's reason,
and its reasoning is sealed in the receipt. Under #676's reading child the
contract job is planned in the child from the per-method timings the parent
sends, bounded as a job naming its chosen method plus its reasoning, kept
across a restart. Both verifiers (Rust and receipt_verify.py) check the
planner statement beside wasmQ's; the receipts corpus is regenerated with
both kinds (268 crafted receipts, 14 plants caught). The views page carries
its engine raw-deflated and stays under its 1 MiB limit (669,484 bytes).

Passed before the push (Framework, linux; M3, macOS): every repository
check, receipts conformance, breaking, corpora, catalogue, the qpu clients,
energy (wai-rs, wai-quantum full, serve), the CLI tests and clippy, writer,
smoke, cross-simulator corpus, job receipts, wasmQ tests and vectors, the
engine with and without receipts under -D warnings, the docs pages, and the
service suite with clippy.
