crates.io README is empty — include directive excludes README.md from package

[randlee]

The crates.io/api/v1/crates/wyvern-cli/0.1.0/readme endpoint returns empty content.

Root cause: crates/wyvern/Cargo.toml has:

include = ["src/**", "ui/**", "Cargo.toml"]

The readme = "../../README.md" field is present, but the include whitelist excludes the README from the published package (it lives outside the crate directory).

Fix: Add "../../README.md" to the include array:

include = ["src/**", "ui/**", "Cargo.toml", "../../README.md"]

Or alternatively use a crate-local README and point readme at it.

Note: This affects all 6 crates that share readme = "../../README.md" — they all need the same fix to get the README rendered on crates.io.
