PR title

Add jpcite — Japanese public-program evidence API (139 MCP tools, first-party citation)

PR body (operator pastes this on GitHub)

## Summary

Adds **jpcite** — a Japanese public-program evidence API + MCP server — to cursor.directory.

- **139 MCP tools** at default gates (146 runtime, 7 in source pending manifest bump)
- **11,601 補助金・融資・税制・認定 programs** + 6,493 laws full-text + 2,065 court_decisions + 1,185 行政処分
- **First-party citations only** — every row carries `source_url`, `source_fetched_at`, `corpus_snapshot_id`, `known_gaps`. Aggregators are banned from the source pool.
- **No LLM inside.** Production code never imports anthropic / openai / google.generativeai / claude_agent_sdk. CI-enforced by `tests/test_no_llm_in_production.py`.
- **Anonymous 3 req/day free tier** (per IP, JST midnight reset). Paid `¥3/req` 完全従量 (税込 ¥3.30).
- **MCP install:** `uvx autonomath-mcp` (PyPI package name is `autonomath-mcp` for backward compatibility; user-facing brand is jpcite).
- **OAuth 2.1 Device Flow** supported for browser-less agent setups (Cursor headless / CI runner / Cline / smol-agents).

## Why Cursor users want this

Cursor agents working on Japanese SMB / compliance / 補助金申請 / 税務 / 法令調査 routinely need to cite Japanese government program data, but the public web is mostly aggregator-rewritten and lacks `source_url + fetched_at`. With jpcite as an MCP tool, the agent can answer "this 補助金 is administered by 経済産業省, source: <official URL>, fetched 2026-05-11" with full provenance preserved.

## Supported tool families

- **Search & evidence** — search_programs, get_evidence_packet, previewCost
- **Company baseline** — createCompanyPublicBaseline, createCompanyFolderBrief, createCompanyPublicAuditPack
- **Compatibility & composition** — apply_eligibility_chain, find_complementary_programs, compatibility_matrix
- **Amendment tracking** — track_amendment_lineage, policy_upstream
- **Industry packs** — pack_construction, pack_manufacturing, pack_real_estate
- **Tax surface** — tax_rule_full_chain, list_tax_sunset_alerts, prepare_kessan_briefing
- **DD / audit** — match_due_diligence_questions, cross_check_jurisdiction
- **Application kit** — bundle_application_kit, subsidy_roadmap_3yr, deadline_calendar

## Verification

- ✅ Registry manifest live at https://jpcite.com/server.json
- ✅ OpenAPI agent profile at https://jpcite.com/openapi.agent.json (34 paths)
- ✅ Streamable HTTP transport at https://api.jpcite.com/v1/mcp
- ✅ Discovery at https://jpcite.com/.well-known/mcp.json

2. `jpcite_evidence_packet_cursor.png` — get_evidence_packet rendered with corpus_snapshot_id + known_gaps.
3. `jpcite_install_uvx.png` — terminal showing `uvx autonomath-mcp` install + MCP probe.

## Notes for reviewer

- The PyPI package is named `autonomath-mcp` for backward compatibility; please do not rename the install command. User-facing brand is `jpcite` and that's what should appear in the directory.
- This is a resubmit of an earlier draft; the previous submission was paused while we finished §B2 robots.txt + .well-known/openapi-discovery.json + OAuth device flow (all live as of Wave 19, 2026-05-11).

Closes #(prior submission issue if any).

Operator pastes the JSON fragment into the appropriate mcps.json / data/mcp-servers.json file, attaches the 3 screenshots, and posts the PR body above. Claude does not have direct push permission to the cursor org, so this last step remains a user-side operation. (Same pattern as Wave 16 §G3.)
