This wires it in properly: - agentloop.Loop: add CompressMessages hook, invoked before every model request; the compressed history is sent to the provider while the persisted session history stays intact. Failures fall back to the original messages so a run never breaks. - agentloop/headroom_hook.go (correct package): adapter bridging headroom.Compressor to Loop.CompressMessages over []session.Message. - loopbuilder.Build: construct the headroom hook from HEADROOM_ENABLED env config, wire CompressMessages when enabled, and close it on cleanup. - remove the orphan top-level internal/agentloop/headroom_hook.go. - add loop_compress_test.go proving the hook is invoked, the compressed history reaches Completion, the session history is not mutated, and compression errors fall back gracefully. Verified: go build ./... , go vet, and tests for agentloop/loopbuilder/ headroom all pass.
