The decorator factory drops contextvars=False although direct decoration honors it, unexpectedly making fields context-local.

Forward the option unchanged; retain direct/factory enabled/disabled controls and independent AutoCast behavior. Add an Unreleased edc fix note and correct the ContextVar argument docstring.

Verification

Independent focused 7 passed; bounded edc/epy 138 passed. Original production with final tests: 1 failed/6 passed focused, 1 failed/137 passed bounded.

Limits

Three optional/dependency-heavy modules excluded; chex/JAX, full optional suite, Pyink/Pylint, platform matrix and CI unverified.
