Sister tool to work_item (#341 / Story 2.17) — that one creates issues/PRs; this one updates an existing GitHub/GitLab issue. Patch shape supports: - title — replace title - body — replace full body - body_section — replace ONE H2 section, preserving all other sections verbatim (the AC contract for #287; section is matched after normalizeHeading so case/whitespace variants all collapse to the same key) - labels / assignees — replacement semantics implemented as add/remove diff against the current set on disk (gh issue edit and glab issue update both expose only additive flags) - milestone — GitHub only; GitLab returns platform_unsupported because glab issue update --milestone needs a numeric id and group/project resolution this thin tool does not own - dry_run — short-circuit before invoking the platform CLI; returns the proposed updated_fields and the resolved_body for body_section patches Implementation lives in lib/adapters/work-item-update-{github,gitlab}.ts behind getAdapter() — the handler shell is platform-agnostic, gate-greps clean. Section splicing is in lib/work-item-section.ts so it is unit-tested in isolation. Test coverage: - 8 unit tests for spliceH2Section (lib/work-item-section.test.ts) - 16 subprocess-boundary tests for the GitHub adapter - 14 subprocess-boundary tests for the GitLab adapter - 10 integration tests for the handler (cross-platform dispatch + envelope) 48 new tests; full suite 2194 pass / 0 fail. Validate emits 76/76 tools registered including work_item_update. Closes #287
