[codex] vltima: add owner-certified absorption organ

[4444J99]

Summary

Adds VLTIMA as a first-class, gated absorption organ that turns current redacted evidence into owner-certified action packet candidates without mutating tasks.yaml.

Changes

• Adds spec/vltima/canon.yaml for the VLTIMA membrane, authority classes, owner-certainty states, and packet contract.
• Adds scripts/vltima-organ.py, scripts/vltima-owner-certainty.py, and scripts/vltima-packetize.py.
• Adds limen vltima plan|run|check|status|packetize CLI commands.
• Wires VLTIMA into heartbeat and organ-health behind LIMEN_VLTIMA=1, gated off by default.
• Adds public redacted docs for ideal form, owner certainty, and action packets.
