Closes #124

The Tenkai product entry now provides the job-submission contract dependents
already require. deploy/tenkai.toml ends with a profile v2 block that
provides "kako.jobs" = "1.0.0". That version is generated from the shipped
JSON job document (JobFile / ScoringFile). scripts/validate-release.sh
refuses a product whose profile does not match.

Reuse decision

Reuse Tenkai [compatibility] v2 provides and the generate-then-check
pattern already used by sibling products. The new edge is kako's job-document
field map plus the committed deploy/tenkai.toml. Contract id is kako.jobs
so existing optional requires stay valid. No Tenkai client and no new
job-submit endpoint.

Focused coverage in crates/kako/tests/release_packaging.rs and
kako::job_contract unit tests: committed product matches the generated v2
profile; a mutated provides-version, contract id, or profile version is
refused; Python parse of JobFile agrees with the Rust field list.

Clean: no accepted/actionable findings.

Simplify-change

Kept the dual generators (Rust for in-crate tests, Python for
validate-release.sh with no cargo). Kept the explicit version-table match
arm so editing the live field list fails closed instead of silently staying
at 1.0.0. Dropped nothing else from the Issue.

Compatibility

• Product version stays 0.1.0; the contract version is independent.
• Profile version = 2 is required by Tenkai ADR 0043. Servers older than
  profile v2 refuse this manifest.
• kako declares provides only. Dependents keep their own optional
  requires.
• JobSource, sandbox, engines, and the job document schema are unchanged.

Validate-behavior

Skipped: no operator-facing UI, CLI, or HTTP flow. Acceptance is the
committed profile and the release check, covered by the tests above.

Agent Transcript

Goal: Land kako #124 so the Tenkai product provides kako.jobs at a generated stable version.

Key decisions:

• Contract id kako.jobs at 1.0.0 so dependents' existing optional requires stay valid.
• Pin is a digest of kako@<product.version>, matching sibling generate-then-check.
• Dual generators: Rust for tests, Python parse of JobFile for validate-release.sh.

Changes made:

• deploy/tenkai.toml: profile v2 provides "kako.jobs" = "1.0.0".
• kako::job_contract plus scripts/tenkai-profile.py: generate and check.
• Release packaging tests drive both generators; stale stand-ins are refused.
• README, RELEASING, ADR 0008: product provides the job-submission contract.

Verification:

• Local AGENTS.md gates: passed.
• validate-release.sh: passed.
• Autoreview local/codex: clean.

Skipped/deferred:

• No CHANGELOG or workspace version bump (release-owned).
• No new HTTP job-submit endpoint.
