Cryptid Core Co Field Operations

v0.9.0-g — Stage 9e: Voice Retrim + Farewells Fixed - **Greeting recordings no longer include spoken line numbers.** The uniform 0.35s trim in 9d wasn't enough to catch the "one," "two" count-ins Xander read before each line. Now every greeting is trimmed to the actual first silence gap after the number. Added - **Farewell sounds for Agents X, T, J, and N.** Random 1-of-2 variants play when their merchant screen closes. Sourced from Section 8 of Xander's recording ("Mm-hm," "Anything else?," etc.). Ropo and Field Agent farewells deferred (their quest screens close via network layer, needs separate hook).
