fix(javascript): exclude class member keys from lexical reads

Classify noncomputed class member keys and private names at the shared reference owner, avoiding false reads and closure captures. Preserve computed keys and initializer/body reads.

Validation: regression controls, fresh public CLI/MCP workflows and complete exact-head CI passed.

Fixes #3310.
