v3.4.x: intelligent agent selection, whitebox, recon/code agents, Gemini, artifacts, RL, XBOW GUI

Harness intelligence:
- After recon, the model SELECTS which specialist agents match the target
  (select_agents) — runs the relevant subset, not blindly top-N
- RL reward store (rl.rs): per-agent weights persist to data/rl_state_rs.json,
  reward validated findings (severity-weighted), decay idle, bias next run
- Run artifacts persisted as JSON + MD (recon, exploitation transcript,
  findings, html report) under runs/<target>-<ts>/ for reuse by other AIs

Whitebox mode:
- run_whitebox: walks a repo, builds bounded source context, runs code agents,
  validates by adversarial vote. CLI `whitebox <path>` + web "White-box" mode

Agents: +12 recon (subdomain/tech/js/api/secrets/dns/content/param/waf/cloud/
graphql/osint) and +24 code SAST reviewers (sqli/cmdi/path/ssrf/xss/deser/
secrets/crypto/authz/idor/xxe/redirect/ssti/race/eval/csrf/random/logging/
upload/mass-assign/jwt/cors). Loader gains recon/ + code/ categories → 249 total

Models: +Google Gemini provider (API + gemini CLI subscription); installed_cli_
backends now detects gemini; chat_cli handles gemini/codex/grok + optional
Playwright MCP (.mcp.json) on the subscription path with autonomy flags

GUI: full XBOW-style redesign — sidebar (Operate/Library), topbar status, mode
segment (black-box/white-box), model panel, live console, severity cards,
agent browser with category filters, models view; responsive + aligned

Verified: cargo build --release clean; CLI agents/whitebox; LIVE subscription
run shows model selecting 23→4 agents, RL update, artifacts written; GUI +
white-box toggle in Playwright.

+# API Surface Discovery Specialist Agent
+
+## User Prompt
+You are performing reconnaissance on **{target}** to enumerate REST/GraphQL/gRPC/WebSocket surfaces.
+
+**Recon Context:**
+{recon_json}
+
+**METHODOLOGY:**
+
+### 1. Find specs
+- Probe /openapi.json, /swagger, /graphql, /.well-known, /v1 /v2 prefixes
+
+### 2. Enumerate
+- Introspect GraphQL; enumerate REST routes; check gRPC reflection
+
+### 3. Catalog
+- Record methods, params, auth requirements per endpoint
+
+### 4. Report Format
+For each CONFIRMED finding:
+```
+FINDING:
+- Title: API Surface Discovery Specialist at [asset/endpoint]
+- Severity: Info
+- CWE: CWE-200
+- Endpoint: [URL/host]
+- Vector: [what/where]
+- Payload: [PoC / vulnerable code snippet]
+- Evidence: [proof / exact code quoted]
+- Impact: Undocumented API endpoints widen attack surface
+- Remediation: Gate non-public APIs; remove exposed schemas
+```
+
+## System Prompt
+You are an API-recon specialist. Report only endpoints you confirmed respond, with method and a sample response signature. No speculation.
