📌 Description

This pull request enhances the interactive web playground by adding real-time search and event filtering for the cryptographic audit console stream across both implementations:

1. The standalone vanilla playground (panopti/playground.html)
2. The Next.js landing playground (agentwatch-landing/app/playground/page.tsx)

Key Additions & Changes:

• Filter Toggle Buttons: Added [All], [Vetoes Only], and [Approved Only] filter toggles with cyberpunk-themed active state indicators (neon cyan --accent, danger --danger, and success --success).
• Real-Time Search Bar: Instant client-side search input filtering by tool name, tag, or payload keywords, accompanied by a quick-clear (✕) button.
• Dynamic Event Counter & Empty State: Integrated a live counter (Showing X / Y events) and an informative fallback message (⚡ No audit events matching current filter or search criteria.) when no logs match the active query.
• Zero Latency & Dynamic Stream Interception: Newly intercepted events automatically respect the currently active filter and update counters immediately without page re-renders.
• Mobile Responsiveness: Implemented responsive flex-wrapping and stacked touch-friendly controls on screens < 600px.
• Zero-Dependency Vanilla Implementation: Maintained pure HTML5/CSS3/ES6 JavaScript in panopti/playground.html.
• Type-Safe React State: Implemented clean React state hooks (filterMode, searchQuery) and memoized stream computation (useMemo) with Tailwind CSS in Next.js.

Fixes #774

🏛️ Architectural Plane & Classification

Which architectural plane does this change target? (docs/v3/V3_ARCHITECTURE.md)

• Plane A: Evidence Plane (Sensors, RawObservation, Ingest, Redaction)
• Plane B: Interpretation Plane (Normalizers, ComputationalEvent, Entity Resolution)
• Plane C: Structure Plane (Hyperedge Store, Execution/Information/Causal Graphs, Provenance)
• Plane D: Model Plane (Latent States, Motifs, Behavioral Genome, Drift)
• Plane E: Experiment Plane (Replay L0–L4, Timelines, Counterfactuals)
• Plane F: Interface Plane (API, Typer CLI, Next.js Frontend)
• Documentation / CI Maintenance

🧪 Verification & Evidence of Testing

1. Test Summary

A total of 19 distinct manual and automated verification test cases were conducted across both environments:

• Scenario Interceptions (5 test cases):

  1. Adversarial SQL Injection (DROP TABLE users;) -> Emits [VETO] with red highlight.
  2. Tool Oscillation / Deadlock Loop (retry_count: 8) -> Emits [VETO].
  3. Unverified State Mutation (0xAttacker) -> Emits [VETO].
  4. Nominal Safe Read (fetch_catalog) -> Emits [ALLOW] with green highlight.
  5. Initial engine bootstrap event ([INIT]).

• Filter Modes (3 test cases):
  6. [All] mode -> Displays complete stream (INIT, VETO, ALLOW).
  7. [Vetoes Only] mode -> Filters exclusively for blocked invariant breaches (VETO).
  8. [Approved Only] mode -> Filters exclusively for verified tool executions (ALLOW).

• Search & Substring Queries (6 test cases):
  9. Exact tool name query: "execute_sql" -> Correctly isolates SQL events.
  10. Partial keyword query: "Invariant" -> Matches invariant violation descriptions.
  11. Parameter query: "retry_count" -> Matches parameter text.
  12. Case-insensitivity test: "veto", "VETO", "Veto" -> Yields identical filtered results.
  13. Non-matching query: "nonexistent_tool" -> Triggers empty state fallback.
  14. Clear button (✕) -> Resets search query and restores stream view instantly.

• Combined Multi-Condition & Dynamic Behavior (3 test cases):
  15. Active filter Vetoes Only + search "transfer_funds" -> Correctly isolates single vetoed mutation.
  16. Dynamic interception with active filter -> Newly intercepted events immediately inherit filter rules.
  17. Empty state fallback -> Correctly displays when combined conditions yield 0 results.

• Responsive Layout (2 test cases):
  18. Desktop viewport (> 900px) -> Inline toolbar alignment.
  19. Mobile viewport (< 600px) -> Controls stack gracefully into full-width touch targets.
