Scope: name expected echoes, make scope-review optional, remove Jira sync

[tobrun]

Summary

Scope runs wrote echoes like D-x (✓ short label) from memory and the first lint-spec.py pass rejected dozens of them, because the text after the check mark must be copied from the chosen line.
The lint error now names what the echo should be, and scope's echo sentence tells authors to lead each chosen line with the label they will echo.
Found by /dev:reflect thread scope-echo-lint-mismatch in two runs across two repositories.

Also in this PR

• scope hand-off: scope now recommends build as the default next step and mentions scope-review only when the change is large or complex, leaving that choice to the user. build never required a review; only the closing line of scope read that way.
• Jira sync removed: the opt-in Jira mirror through acli is gone from the dev skills and the factory phase copies - the scope and build sections, the Epic key prefix on ship's branch and PR title, the jira.md reference, its evals and stub fixture, and the docs describing it. build keeps its work-branch rule under its own heading, and .dev/config.json stays for the run journal opt-out.

Evidence

Same spec fixture (chosen line S3 bucket - durable across redeploys, echoed as (✓ cloud storage)), run through the linter at the merge base and on this branch.

On merge base

$ python3 lint-spec.py spec.md
spec.md: no '## Change Plan' section
spec.md: no '### Validation' block in the scope section
spec.md:11: D-storage echo '(✓ cloud storage)' does not match its resolution

3 problem(s); the spec is not final.

On this branch

$ python3 lint-spec.py spec.md
spec.md: no '## Change Plan' section
spec.md: no '### Validation' block in the scope section
spec.md:11: D-storage echo '(✓ cloud storage)' does not match its resolution; expected (✓ <text copied from: s3 bucket>)

3 problem(s); the spec is not final.

Open calls

• Hint text is unquoted and uses a <text copied from: ...> placeholder, unlike the spec's quoted Error format (review concern, minor).
• Test tightening: pass-case tests check only filtered stdout, the hint assertion is a loose substring, and the change-plan tests bypass the lint() helper.
• hint is built eagerly then overwritten in two branches (simplify).
