fix: restore full export surface (telemetry, token-usage, profile-security, sandbox-size)

The initial extraction was taken from a stale develop checkout and dropped
telemetry/{content-attributes,spine-attributes,index,token-usage} and the
agent-interface profile-security/sandbox-size modules. Re-extracted faithfully
from origin/develop. agent-interface 0.11.0->0.11.1, agent-core 0.2.0->0.2.1.
