v0.14.0 — closed-loop optimizer

Closed-loop hill-climber over Kconfig: autokernel iterate runs propose → check → apply → build → boot-test → measure for N rounds, feeding results into the next propose call as context.

Four-axis intent (workload × threat × modules × aggression) composed via 13 named presets (gaming-desktop, paranoid-laptop, hardened-server, cloud-vm, lean-static, hyperoptimize, …) or per-axis flags.

Static config validation catches LLM hallucinations + dead-letter choices before the slow build.

Live verified: i=1 88 proposals → i=2 83 proposals (5 fewer because i=1's accepted trims became baseline). 699 tests, ~6s.
