Feat/codexsaver inspired routing (#66)

* feat: parallel tool execution + RTK-inspired tool result compressor

- Universal tool→shell converter handles arbitrary tool counts (model decides)
- Unique tool_use ID generation with sequential counter to prevent collisions when models batch many calls
- New src/context/tool-result-compressor.js: 10 RTK-inspired compressors for test output, git diff/status/log, lint output, build output, directory listings, large file skeletons, JSON, container output
- Tier-adaptive compression thresholds (SIMPLE/MEDIUM/COMPLEX/REASONING)
- Tee recovery cache (5min) — full output retrievable via /tee/:id
- Compression metrics endpoint /metrics/tool-compression
- Skip JSON compression on web_search/web_fetch results (preserve search content)
- Convert Anthropic web_search_20XXXX server tools to function tools so non-Anthropic providers can execute them
- Map item.content alongside snippet/summary/excerpt for SearXNG result parsing
- Diagnostic logging for incoming tool types

* feat: add web dashboard UI at /dashboard

Adds a zero-dependency, no-build-step SPA dashboard served by Express:

- Overview: stat cards (requests/tokens/cost/saved), provider health,
  recent requests table with live timestamps
- Usage: 1d/7d/30d/all window selector, stacked bar chart by tier,
  breakdown tables by tier / provider / model
- Routing: tier definition cards, routing accuracy panel,
  per-provider stats table, circuit breaker states
- Logs: filterable 100-row request log with provider/tier/error filters

Auto-detects the active time window (24h → 7d → 30d → all) so panels
never show empty when no requests were made in the last 24h.
Provider stats are derived from actual DB rows rather than config,
so any provider that handled traffic appears automatically.

* added united

* chore: remove local tooling artifacts from PR

Untrack .claude/, .claw/, .deepsec/, .lynkr/ and add them to .gitignore.
These directories contain local session state, settings, and telemetry
that shouldn't be checked into the repo.

* chore: remove remaining CodexSaver attribution comments

Strips four upstream attribution comments from risk-analyzer.js,
interaction.js, config/index.js, and .env.example. No behavior change.
