merge: reconcile Wave 1.1 with post-PR40 lab

Merge canonical lab 9557b8d5909eb4a885c3bf49e19a65dd904f8c1d exactly once.
Retain invocation journal ownership and lineage, provider terminal ordering,
teacher handoff, framed DONE handling, and canonical authority/Ajax routing.

Combine dynamic dispatch receipts with lab policy forwarding. Adapt native
shell/patch evidence, explicit TUI verifiers, and artifact recovery presentation.
Refresh generated configuration source links and strengthen adapter regressions.

Validation: focused 2118 passed; Wave 1.1 script 2291 passed; broad runtime
5649 passed; full pytest 11581 passed, 53 skipped, 2 xfailed, 6 subtests passed.
Compileall 1689 Python files; syntax 279 JS and 82 MJS files; diff and
conflict-marker checks passed.
