[TASK][PROGRAMME.T09] Run the OS distribution and Rust-kernel programme

Parent: #1

Task ID: `PROGRAMME.T09`

## Proposed implementation
Package the user-space runtime as a session/distribution and staff K0-K4 separately with explicit hardware, ABI, driver, browser and inference compatibility gates. Keep reasoning and generated interfaces unprivileged.

## Done when
P8 and K0-K4 stage plans are owned, and OS progress is measured by real supported workflows and deterministic recovery rather than a boot demo or Rust line count.

## Guardrail
Kernel ambitions must not consume browser security-patch and connector-maintenance capacity required for current users.

## Prerequisites
`PROGRAMME.T03`, `PROGRAMME.T04`, `PROGRAMME.T05`, `PROGRAMME.T06`

Review: pending · Implementation: not started.

Start with parent issue #1 and prerequisites PROGRAMME.T03 through PROGRAMME.T06. Review the proposed P8 and K0-K4 staging, including the hardware, ABI, driver, browser, and inference compatibility gates. Done means the stage plans have owners and progress is measured by supported workflows and deterministic recovery, while preserving browser security and connector-maintenance capacity.
