* fix(#581): add Edit to six writer agents' tools so Edit-only discipline is enforceable

Six writer agents (gsd-eval-planner, gsd-ai-researcher, gsd-domain-researcher,
gsd-phase-researcher, gsd-ui-researcher, gsd-debug-session-manager) shipped with
Write but no Edit in their tools: frontmatter. Their spawn prompts instruct
surgical in-place section edits on existing/shared files (notably the AI-SPEC.md
trio writing disjoint sections of the same file), but with no Edit tool they
fall back to whole-file Write — silently clobbering sibling sections
(last-writer-wins) while still reporting success.

Same bug class as #571, fixed for gsd-doc-writer in #575. This adds Edit
alongside the existing Write for all six (Edit placed adjacent to Write, mirroring
the gsd-doc-writer fix). Write is retained; no prompt-body changes; no other agents
touched.

Adds a regression test (tests/agent-frontmatter.test.cjs) asserting each of the
six section-writer agents carries both Write and Edit.

* chore(#581): add changeset fragment for writer-agent Edit fix

* chore(#581): regenerate changeset via npm run changeset

Replace hand-authored fragment with one generated by the official
scripts/changeset/new.cjs script (correct <adjective>-<noun>-<noun>
filename convention).

Six writer agents (`gsd-eval-planner`, `gsd-ai-researcher`, `gsd-domain-researcher`, `gsd-phase-researcher`, `gsd-ui-researcher`, `gsd-debug-session-manager`) now carry `Edit` alongside `Write` in their `tools:` frontmatter, so the Edit-only discipline in their spawn prompts is enforceable. Previously, without `Edit`, they fell back to whole-file `Write` and silently clobbered sibling sections of shared files such as `AI-SPEC.md`. Same bug class as #571 (fixed for `gsd-doc-writer` in #575). See #581.
