docs(ams): port docs/fleet-run-manifest.md to a website docs page (docs.ams-fleet-manifest.tsx)

[oktofeesh1]

Summary

• Adds content/docs/ams-fleet-manifest.mdx porting packages/loopover-miner/docs/fleet-run-manifest.md to the website: the top-level fleet-operator config for running the miner across many repos — the repos list (per-repo worktree budgets), totalConcurrentWorktrees, and how it contrasts with the per-repo .loopover-miner.yml goal spec — rendered via the existing DocsPage/Callout/CodeBlock/FeatureRow ui-kit primitives, following the pattern set in docs(ams): port DEPLOYMENT.md to a website docs page (docs.ams-deployment.tsx) #6022-docs(ams): port docs/miner-goal-spec.md to a website docs page (docs.ams-goal-spec.tsx) #6030.
• Adds apps/loopover-ui/src/routes/docs.ams-fleet-manifest.tsx, a thin loader + docsClientLoader route matching every other migrated docs page.
• Adds the page to docs-nav.tsx's "AMS: deployment" subgroup and to docs.index.tsx's Maintainers audience card.
• packages/loopover-miner/docs/fleet-run-manifest.md stays as the canonical source: it ships inside the published @loopover/miner npm package. A short pointer to the new website page was added at the top.

Scope

• The PR title follows type(scope): short summary Conventional Commit format.
• This PR is focused: one new docs page + nav wiring, under apps/loopover-ui/**, plus a documentation pointer in packages/loopover-miner/docs/fleet-run-manifest.md.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• Closes docs(ams): port docs/fleet-run-manifest.md to a website docs page (docs.ams-fleet-manifest.tsx) #6031

Validation

• git diff --check
• npm run actionlint
• npm run typecheck
• npm run test:coverage locally — UI-only page addition under apps/loopover-ui/** (outside coverage.include); codecov/patch does not apply
• npm run test:workers
• npm run build:mcp
• npm run test:mcp-pack
• npm run ui:openapi:check
• npm run ui:lint
• npm run ui:typecheck
• npm run ui:build
• npm audit --audit-level=moderate
• Full npm run test:ci run locally from a clean npm ci install, rebased on top of the OLLAMA_NUM_BATCH .env.example fix, green: 912 test files / 17,464 tests passed

Safety

• No secrets, wallet details, hotkeys, coldkeys, user PATs, private keys, raw trust scores, private rankings, or private maintainer evidence are exposed.
• Public GitHub text stays sanitized, low-noise, and does not imply compensation guarantees or optimization tactics.
• Auth, cookie, CORS, GitHub App, Cloudflare, or session changes include negative-path tests. — N/A, no such changes in this PR
• API/OpenAPI/MCP behavior is updated and tested where needed. — N/A, no API/OpenAPI/MCP behavior changed
• UI changes use live API data or real empty/error/loading states, not production mock/demo fallbacks. — N/A, static docs content only
• Public docs/changelogs are updated where needed; changelogs are only edited for release-prep PRs.

Notes

• No UI Evidence table — new content page rendered through the same primitives as every other migrated docs page, no visual redesign.
• Continues the "AMS: deployment" nav-subgroup precedent set by docs(ams): port DEPLOYMENT.md to a website docs page (docs.ams-deployment.tsx) #6022-docs(ams): port docs/miner-goal-spec.md to a website docs page (docs.ams-goal-spec.tsx) #6030.
