DOCS-1823 - Align Claude Code tooling with /docs/contributing - #7069

…and contributing guide

- AGENTS.md: clarify the repo takes both internal and external
  contributions; mark Jira Rules and Jira Commands sections as
  Sumo Logic internal (requires Atlassian access)
- README.md: rename "For Docs Team contributors" to "Claude Code
  tooling" and correct scope — most slash commands work for anyone
  with the repo cloned, only Jira commands are internal-only
- docs/contributing/create-edit-doc.md: note that /doc, /audit-doc,
  and /seo-audit are available to external contributors
- docs/contributing/remove-doc.md: note that /remove-doc automates
  this page's steps
- docs/contributing/style-guide.md: note that the sumo-style skill
  auto-applies these conventions in Claude Code, no invocation needed

Content fixes across README.md and the contributing docs:
- Fix ~20 style-guide violations: em dashes, uncommon contractions,
  missing terminal periods, Markdown capitalization, mislabeled code
  fence languages, an outdated tool recommendation (Atom)
- Tighten wordy/awkward phrasing (CID explanation, minor-fix intro,
  commit-message instructions); fix "Doc Team"->"Docs Team" and
  "content ID" capitalization inconsistencies
- Rewrite the docs/contributing landing page intro: cut generic
  corporate boilerplate that didn't describe this repo, and fix a
  code-vs-docs terminology mismatch ("fixing bugs, adding features"
  on a docs-only repo)
- Add missing card descriptions to the six docs/contributing hub cards
- Apply "Pull Request (PR)" first-reference-then-acronym consistently
  across README and the contributing docs

Structural consolidation:
- Extract the repeated fork/branch/GitHub-tips instructions into a
  shared reuse/contributing/fork-repo.md partial, used by both the
  "Edit a doc" and "Create a new doc" flows
- Move doc-prerequisites.md into reuse/contributing/ and fold the
  VS Code tooling recommendation into it (replacing the now-deleted
  reuse/contributing/tools.md)
- Fix a broken <Tools/> reference and a stale import path left over
  from the moves above
- Trim the "Using Claude Code" tips on create-edit-doc.md and
  remove-doc.md to point at README's policy instead of restating it;
  restore remove-doc.md's page-specific /remove-doc callout after it
  was accidentally overwritten with generic text
- Retitle all "Using Claude Code" tips to "Recommended: Use Claude
  Code"; add a noindex tag and fix a missing verb in the equivalent
  tips on the app-template-v2, c2c-source, and generic-doc templates
- Simplify partner-app-doc.md to defer to app-template-v2.md and
  append only its unique Support section, instead of maintaining a
  separately drifted copy; add a note pointing out that most partner
  apps are documented on the partner's own site or in the separate
  sumologic-public-partner-apps repo, not as a page on this site

New:
- Add docs/contributing/templates/index.md, a hub page for the four
  doc templates, with a tip pointing to the equivalent Claude Code
  slash commands (/doc, /app-doc, /c2c-source-doc, /release-note-*)
  as a faster alternative to copying a template by hand
- Wire the Docs Templates sidebar category to the new hub page

Navigation:
- Add a "Contribute to Docs" entry to the top-nav Guides dropdown,
  matching the existing Support entry

- Add a Docs Templates card to the contributing hub page (index.md) so the
  new templates hub is discoverable from the landing page, not just nav.
- Remove the duplicate "Contribute to Docs" navbar entry from the Support
  dropdown; keep the new one in the Guides dropdown.
- Move contributing/code-of-conduct after the Docs Templates category in
  sidebars.ts so the sidebar order matches the hub page card order.
