Adds Perplexity Sonar, Claude web_search, OpenAI Responses, and Gemini
Grounding as ResearchAgents behind the same comparison interface as the
search and extract providers.
New endpoints:
POST /v1/research — single-agent (or auto-routed to the first
provider with a configured key)
POST /v1/research/compare — fan-out across N agents, persist all
answers + citations in research.eval_*
Each agent normalizes its native response into a common AgentAnswer shape
(answer text + citations[] + tokenUsage), storing the provider's raw
response alongside for later inspection. Implementations use direct HTTP
against each vendor's public API — no SDK deps added.
Auto-routing preference: perplexity-sonar → gemini-grounding →
openai-responses → claude-web-search → (openai-deep-research stubbed for
Phase 3b). Credits orchestration reuses the search/extract executor
pattern (reserve → call → commit/refund).
Deferred to Phase 3b: openai-deep-research (async job queue), migration
of mana-ai + mana-api news-research to call this service directly.

New Bun/Hono service on port 3068 that bundles many web-research providers
behind a unified interface for side-by-side comparison. All eval runs
persist in research.* (mana_platform) so quality can be reviewed later.
Providers (Phase 1+2):
search: searxng, duckduckgo, brave, tavily, exa, serper
extract: readability (via mana-search), jina-reader, firecrawl
Endpoints:
POST /v1/search, /v1/search/compare — single + fan-out
POST /v1/extract, /v1/extract/compare — single + fan-out
GET /v1/runs, /v1/runs/:id — history
POST /v1/runs/:run/results/:id/rate — manual eval
GET /v1/providers, /v1/providers/health — catalog + readiness
Auto-routing: when `provider` is omitted, queries are classified via regex
(fast path, 0ms) with optional mana-llm fallback, then routed to the first
available provider for that query type (news → tavily, academic → exa,
semantic → exa, etc.).
Credits: server-key calls go through mana-credits reserve → commit/refund
so failed provider calls don't charge the user. BYO-keys supported via
research.provider_configs (UI arrives in Phase 4).
Cache: Redis with graceful degradation (1h TTL for search, 24h for
extract). Pay-per-use APIs only — no subscription-gated providers.
