skill(entry): tighten draft revision rules and extend promote gate

[dean-harel]

Summary

• Voice rules. Replace the misleading [reference] shorthand wording with inline [label](url) markdown links — what published entries actually do. Add rules for non-thematic word repetition and for bold/italic emphasis.
• Revise Draft. Read the surrounding paragraphs before editing so revisions preserve flow, not just satisfy the request in isolation.
• Promote gate. Extend the existing title check with URL validation and citation coverage. Both surface issues non-blockingly; the user can fix inline or proceed.

The principle behind the promote changes: the post-promotion pipeline is slow, costs money, and runs remotely. Anything checkable on local text moves before promotion. Stages 4–6 only catch what genuinely needs the audio.

Test plan

• Run `/entry "rough idea"` and confirm research creation still works
• Move-to-Draft, then Revise-Draft a passage and confirm the revise reads surrounding context
• Promote a draft with a known dead link and confirm URL validation surfaces it
• Promote a draft with an unsourced claim from research and confirm citation coverage surfaces it
• Confirm voice.md anti-patterns still load via path glob on draft.md
