Three related fixes from the test audit.
**The CLI journey fixture gets its own database.** It spawned a real picloud —
whose dispatcher/orchestrator claim loops are global by design (one instance owns
one database) — against the shared dev DB, so it could claim the manager-core
suites' outbox/workflow rows (the same class of bug already fixed for the e2e
suites, one binary over). It now clones one dedicated database per journey run
from the migrated template. test-support gains `named_test_db_url` (explicit
stable name) + a blocking wrapper for the sync `LazyLock` fixture. The one journey
that talks to Postgres directly (dead-letter injection) now uses the fixture's DB
URL, not the base DATABASE_URL, so it hits the database the server reads.
**workflow_orchestrator moves to per-test databases.** Its `claim_ready_step` is
global, so the old harness serialized every test behind a process-wide CLAIM_LOCK
AND ran `DELETE FROM workflow_runs` (unscoped — it wiped every app's runs) before
each one. A private database per test makes the global claim see only that test's
rows, so both the lock and the unscoped DELETE are deleted.
**DB-backed suites fail loud instead of skipping green.** ~15 manager-core suites
`return None` when DATABASE_URL is unset and report PASS — so in any environment
that lost its database the entire integration surface reports green while running
nothing (why the CI gap went unnoticed for so long). New
`picloud_test_support::abort_if_db_required` panics when `PICLOUD_REQUIRE_DB` is
set (CI now sets it) but DATABASE_URL is not, injected into each suite's skip
path. Local runs without the var still skip cleanly.
Mutation-verified: with PICLOUD_REQUIRE_DB=1 and DATABASE_URL unset, a suite
panics; without the var it skips.

Turning CI on surfaced `atomic_write` as intermittently failing under load —
self-inflicted. Its fault injection is `CREATE TRIGGER ... ON outbox`, which takes
an ACCESS EXCLUSIVE lock on a table every other suite is concurrently inserting
into. The header even claimed it "cannot affect any test running in parallel";
that was wrong — scoping the trigger by app_id bounds which ROWS it rejects, not
the table lock installing it takes. Shipping that alongside "run the DB tests in
CI" would have poisoned the signal.
The fix is the one already used for the e2e suites: a private database per test.
That logic (build a migrated template once, clone it per test via
`CREATE DATABASE ... TEMPLATE`) was duplicated in `picloud/tests/common`, and this
would have been a third copy — so it moves into a shared `picloud-test-support`
dev-dependency crate, and `picloud/tests/common` now re-exports it. The invariant
it encodes: manager-core's claim loops are global by design, so a test must not
share a database with anything that runs them OR with anything that does DDL.
Moved onto it:
- `atomic_write` — the DDL fault injection above; its per-test cleanup is now
deleted (the database is thrown away).
- `outbox_reclaim` — asserts `reclaim_stale_claims` returns exactly 0, a count
over the WHOLE outbox table. On the shared DB any stale row from any other suite
(or a killed picloud that died holding a claim) would fail it permanently, until
someone cleared the table by hand.
