🔧 - Remove non-existent adapter workspace from consumer test matrix

[turtton]

Why

Both open PRs (#64, #65) fail on emumet-check / Check adapter with:

package `adapter` is not a member of the workspace

Emumet's workspace members are now application, driver, kernel, server — the adapter crate no longer exists, but test-consumers.yml still passes it to check.yml.

What

• Remove adapter from the workspace matrix in test-consumers.yml, matching the matrix in Emumet's own lint-and-test.yml ([ "kernel", "application", "server" ]). driver is already covered separately by emumet-test-psql.

Verification

• Matrix now matches the actual members of Emumet's Cargo.toml workspace.
