[PR] Add Presto platform with engine-only integration tests [wayang]

JunWang222 opened a new pull request, #773:
URL: https://github.com/apache/wayang/pull/773

   ## Summary
   
   This PR adds the Wayang Presto platform implementation and engine-only integration tests.
   
   ## What is included
   
   - Adds `wayang-presto` platform module.
   - Adds Presto mappings/operators for:
     - TableSource
     - Filter
     - Projection
     - Join
     - GlobalReduce
     - ReduceBy
     - Sort
     - TableSink
   - Adds end-to-end `PrestoOperatorsIT` coverage for each operator.
   - Adds JavaPlanBuilder integration tests that simulate user-facing API usage.
   - Keeps the integration tests engine-only by registering only `Presto.plugin()`.
   - Uses self-contained in-memory Presto fixtures created by the test setup, without requiring external datasets.
   
   ## Validation
   
   - Rebased on latest `apache/wayang:main`.
   - Presto operator tests are designed to run against the local Presto setup and skip when Presto is unavailable.

   Hi Jun, there is some test failing in the sql api. Could you take a look? I think it's the same in all three PRs
