Why?

Fix an existing master defect: ordinary POST requests ending in /search currently hoist limit even for custom methods. #4233 exposes this through added coverage, but is neither the cause nor the base of this fix.

What?

• Add _request_v2_search and _request_v2_search_async, each splitting URL/body before one ordinary-request delegation.
• Delete suffix-based hoisting from _request and _request_async.
• Preserve options, base address, usage, parameter encodings, and single coercion. Copy caller params and preserve any existing-query URL byte-for-byte.
• Cover paired sync/async dispatch, absent limits/null params, ordinary custom requests, encoding, immutability, and pagination.
• Add a patch changefile documenting migration for handwritten low-level search services.

Validation: just test (4,371 passed, 7 skipped); just lint; just format-check; just typecheck; just typecheck-examples pass. Focused search suite: 17 passed. GA regeneration produces no generated changes.

Additional acceptance in disposable worktrees only: #4233 head 5508bd65545fe39e9ebd99eba249f642f1434e1a, Python private-preview baseline 481b84d7. just run-with-capture /tmp/search-gen-python.txt gen python --private-preview --repo=<temporary Python worktree>, then just test tests/test_generated_examples.py -n 0 (3,559 passed) and -k test_v2_data_operation_search_post_all_service pass. No preview generated files are included here.

Reviewed #1939: preserve sync/async POST pagination with the original body and request options. Existing request signatures remain usable; handwritten low-level search services must opt into the dedicated helper. Runtime helpers must ship before codegen-generated calls are released.
