Adds createHttpStudioGateway, the adapter the Studio UI calls in
production. It drives every mutation through mutationIntent()
(defineMutationIntent/defineIdempotencyKey, not
createBrowserMutationIntentFactory, so the caller-supplied idempotency
key is preserved rather than regenerated) and leaves header
construction to the executor/credential collaborator entirely - the
gateway never sees or sets Idempotency-Key or x-csrf-token itself.
Also moves stable-stringify.ts out of adapters/mock/ so the mock and
http adapters share one pure function without production code
depending on the mock directory, and fixes the resulting import in
cursor.ts, mock-studio-gateway.ts, and mock-studio-gateway.test.ts.
Adds MSW handlers (tests/mocks/handlers/tech-log-studio.ts) that wrap
the reference mock-studio-gateway implementation, and a contract test
suite that drives the gateway through a thin fetch-based executor
built from the contract's own projectRequest, proving canonical
path/body/header construction without assembling the full platform
transport.

Round 3 of the TechLog contract task added two pieces of genuinely new
logic with no assertion on their output: the totals.needsValidation
count in getDashboard(), and the detail() rewrite that avoids a
self-reference when computing WorkingCopyDetail.nextAction. Both would
have passed every existing test if they regressed.
- needsValidation is checked against an independent count derived from
listDocuments()'s per-document nextAction, with sanity bounds so a
filter that always returns 0 or the full count can't pass silently.
- detail()'s nextAction is asserted on two fixtures whose expected
value is justified by the asserted preconditions alongside it
(published-at-current-version -> NONE; INVALID-but-current-validation
-> FIX_VALIDATION). Verified locally that hardcoding nextAction to a
constant in detail() makes the second assertion fail, and that
zeroing needsValidation's count makes the dashboard assertion fail.
