Durable Playbook actions need adapters for agent turns, workspace operations, validation, and human-approved publication.

Add the development adapters and publication flow. Agent results use the exact run's final reply, optionally unwrap one JSON fence, and keep schema and artifact-hash validation strict; progress messages no longer invalidate otherwise valid evidence.

Stack 3/9. Depends on #157. Merge in order, retargeting to j5/main as predecessors land. Full-stack testing branch: codex/playbooks-09-aurora-loops.

Validation at the integrated stack tip: 179 server/shared tests and 104 web tests passed; server and web typechecks passed. Each regenerated runtime manifest was checked. The adapter slice independently passed 92 tests, including the parser regressions.

Heads-up: this PR touches Squadron code that is being removed.

What changed on j5/main (2026-10-08). J5 is retiring Squadrons and folding their behavior into projects (#412, decided 2026-10-05). The client half has merged (#454, #455, #456):

• The Squadron picker, draft chip, sidebar Squadron filter, first-run gate and the Create, Rename and Delete Squadron dialogs are gone. Most of apps/web/src/j5/squadron/ is deleted.
• New threads, drafts, the sidebar filter and Add Project use upstream's project flow again.
• The Fleet page, Inbox and thread cards read the thread's project.

Still to come. The server migration re-keys the ledger from Squadrons to projects, removes list_squadrons and join_squadron, and renames squadron_id / squadronId to project fields across the server, the shared contracts and the peer protocol. After that, a rename pass removes the word from the remaining code.

For this PR. It uses Squadron ids in about 11 changed lines in apps/server/src/j5/playbook/AgentAdapter.ts and the fh/development definition and tests.

When you next rebase: use the thread's or workspace's projectId where this uses a Squadron, in stored rows, contracts and queries alike. No Squadron needs to be chosen or sent when a thread is launched; the server derives the home from the project. The smaller PRs in this stack (#163, #159, #143, #164) have one to four such lines each and need the same change.
