Nicky LeachandPaperclip dc6dd23ea4 Add plugin Runner preparation task contract (#16993)
## Thinking Path

> - Paperclip manages work for AI agents.
> - Environment plugins can own Runner tasks.
> - Core selects provider policy and runtime assignments.
> - The execution environment must resolve its own paths and
configuration.
> - The task API needs a preparation exchange before execution.
> - This PR adds that exchange under the existing lease authority.

## Linked Issues or Issue Description

**Problem or motivation**
The environment task API can start a Runner. It cannot return a prepared
provider configuration from Core requirements.

**Proposed solution**
Add a versioned `prepare` request and `prepared` result. Keep the
provider configuration bound to its task and requirements. Check the
same company, run, project, and retained-session authority as
submission.

**Alternatives considered**
A shell preparation command would expose execution details in the API.
Provider-specific ownership flags would spread this contract across
backends.

**Roadmap alignment**
This extends the existing plugin and remote execution APIs. It does not
add a separate execution system.

Refs #16977, #15406. The prerequisite #16977 is merged. This PR now
targets master. Runner transport and provider implementations follow
separately.

## What Changed

- Add strict launch requirements and prepared result schemas.
- Add the preparation capability version and saved configuration ID.
- Apply existing lease and resource checks to preparation.
- Document idempotency, cancellation, recovery, and cleanup
requirements.

## Verification

- `pnpm -r typecheck` passed.
- Plugin SDK build passed.
- All 55 Dot Runner and native Codex server integration tests passed
with Cargo available on PATH.
- All 18 environment task runtime tests passed. These include
preparation dispatch, inactive leases, wrong run identity, unauthorized
projects, result identity, and unknown command rejection.
- The broader root suite on the parent refactor finished with 22,420
passing tests, seven failed tests in unchanged Git and diagnostic code,
and two suite setup errors because Cargo was absent from its PATH. This
PR does not claim a passing full root suite.
- No live provider calls or deployment were run. 
- Standard Greptile and Apex each scored commit
`d3ac15906240b7066f5ff505ed2ffd9ef5dd43c1` 5/5. There are no unresolved
review threads.
- All 55 CI checks passed. Two optional checks were skipped. The branch
is ready and mergeable against master.
- A fresh master fetch and merge-base check passed immediately before
the Apex request.

## Risks

- This defines a new optional worker operation. Existing providers keep
their current operations.
- A provider must validate policy and resource bindings. Schema
validation alone does not validate a concrete provider descriptor.
- This PR defines the exchange. It does not connect native execution to
a preparation provider.

## Model Used

- OpenAI Codex, GPT-6. Reasoning and repository tools. The exact serving
model identifier and context size are not exposed in this session.
