fix: preserve int map entries during resize

[imbajin]

Purpose of the PR

Concurrent table growth could hash a key using one generation and access another, losing entries. A competing chain update could also make removal report an existing key as absent.

Main Changes

Hash against the captured table's length and retry a failed compare-and-set while the key is still present. Add parallel growth checks for reads, removals, retained values and final size.

Verifying these changes

• Trivial rework / code cleanup without any test coverage. (No Need)
• Already covered by existing tests.
• Need tests and can be verified as follows:
  • Native regressions fail the original implementation and the first partial fix; the final candidate passes the IntMap suite.
  • Java 17 clean compilation, EditorConfig formatting and three independent reviews passed.
  • Current org/ASF CI is checked separately after delivery.

Does this PR potentially affect the following parts?

• Dependencies
• Modify configurations
• The public API
• Other affects: internal concurrent collection correctness
• Nope
