refactor(create-expert): simplify verbose descriptions in delegates

[FL4TLiN3]

Summary

Simplifies expert descriptions to focus on capability rather than input/output details.

Changes

Expert	Before	After
property-extractor	"Extracts testable properties from user requirements. Provide requirements text. Returns user properties, Perstack properties, usability properties, and external dependencies."	"Extracts testable properties from user requirements"
ecosystem-builder	"Creates Expert ecosystem from properties. Provide extracted properties and requirements. Returns perstack.toml with main, demo, and optionally setup/doctor experts."	"Creates Expert ecosystem with main, demo, setup, and doctor experts"
integration-manager	"Orchestrates functional and usability testing in parallel. Provide ecosystem info and properties. Returns integration report with scores and recommendations."	"Coordinates functional and usability testing, returns quality assessment"
functional-manager	"Runs happy-path, unhappy-path, and adversarial tests. Provide properties and ecosystem. Returns functional test report with pass/fail counts."	"Runs happy-path, unhappy-path, and adversarial tests"
usability-manager	"Tests usability of expert ecosystem (demo, setup, doctor, errors). Provide ecosystem and properties. Returns usability report."	"Tests usability of expert ecosystem (demo, setup, doctor, errors)"
expert-tester	"Executes tests against experts. Provide stage, expert name, properties, and test cases. Returns property-wise pass/fail results."	"Executes tests against experts and reports property-wise results"

Per docs/making-experts/README.md, description should answer "what can I ask for?" - input/output details belong in instruction.
