… map for multi-service packages (#4650) Fixes #4009 ## Summary Extends the TCGC `api-version` emitter option to accept either a `string` or a `Record<string, string>` (a map from each service namespace's full name to its desired version), enabling per-service version selection for multi-service packages. ## Behavior - **`string`** (e.g. `"2024-10-01"`): applies to single-service packages only. Ignored for multi-service. - **`"latest"`**: global keyword, applies regardless of service count. - **`"all"`**: single-service only. **Multi-service packages do not support `all`** (in either string or map form) — it is ignored and each service falls back to its latest version. - **`Record<string, string>`** (e.g. `{ "ServiceA": "av1", "ServiceB": "bv2" }`): maps each service namespace full name to a version. Services not listed default to their latest version. ## Implementation notes - Added `resolveApiVersionForService` as the single source of truth for resolving the version that applies to a given service. - `getServiceNamespaces` is memoized on the context (`__serviceNamespaces`) since it is consulted on the per-type hot path via `getAvailableApiVersions`. - `handleVersioningMutationForGlobalNamespace` now mutates each service independently using its resolved version. ## Validation - Added multi-service map tests (per-service versions, fallback to latest, `all` ignored). - Full TCGC suite: 1330 passed / 2 skipped. TypeScript build and ESLint clean. --------- Co-authored-by: tadelesh <chenjieshi@microsoft.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: iscai-msft <isabellavcai@gmail.com>

Hotfix (patch) release for `@azure-tools/typespec-java` **0.45.6 -> 0.45.7** from the `release/july-2026` branch. ## Changes included - Fix per-client `ServiceVersion` regression after migrating from js-yaml and lodash. - Remove `@azure-tools/typespec-liftr-base` and `@azure-tools/openai-typespec` from peer and dev dependencies. - Support `clientApiVersions`. ## Notes - Version bump generated via `pnpm chronus version --ignore-policies`. - The `clientApiVersions` changeset was authored as `feature` but is released here under a **patch** bump (consistent with prior hotfix precedent, e.g. #4670); all entries appear under **Bug Fixes** in the changelog. - `core` submodule pointer unchanged. - Only `@azure-tools/typespec-java` is bumped; unrelated pending changesets are untouched. Targets `release/july-2026` (not `main`). Backmerge to `main` to follow after merge.
