Patrick Buckley 9be155b97a Quality overhaul: code tooling, CI/CD, architecture diagrams, UI rede… (#1)
* Quality overhaul: code tooling, CI/CD, architecture diagrams, UI redesign, and legacy cleanup

- Add ruff (lint+format) and mypy (strict) with zero errors across 37 source files
- Add GitHub Actions CI (lint, typecheck, test matrix 3.11/3.12/3.13) and PyPI publish workflow
- Create 12 PlantUML architecture diagrams with PNG renders covering all subsystems
- Refresh README and docs with badges, diagram links, and current descriptions
- Refactor test_server_live.py with mock streaming helpers for deterministic CI testing
- Update dependencies to current versions (openai>=2.24, httpx>=0.28, redis>=7.2)

Console dashboard:
- Move state indicators from top cards to fixed bottom status bar with cluster metrics
- Replace flat 50-node list with hostname-prefix grouped nodes (expand/collapse, up to 1000)
- Apply "Instrument Panel" visual redesign: IBM Plex Mono + Outfit fonts, warm amber accent,
  LED glow state indicators, deep charcoal surfaces, WCAG AA contrast compliance
- Add render cache, stale indicator, active filter highlight, loading states

Server web UI:
- Apply matching Instrument Panel aesthetic for visual consistency with console
- Fix branding (pcode → turnstone), extract inline styles to CSS classes
- Rename pcode localStorage keys and history state to turnstone

Legacy cleanup:
- Remove persona-model-specific --persona flag and /persona slash command
- Remove model_identity from chat_template_kwargs (vLLM-specific mechanism)
- Refactor plan agent to use standard developer message instead of model_identity
- Remove dead code (unused date/has_tools variables, noqa suppressions)

* Fix CI typecheck: add mypy overrides for optional sympy/numpy imports

The math sandbox optionally imports sympy and numpy at runtime (try/except
ImportError). In CI these packages are not installed, so mypy raises
import-not-found rather than import-untyped. Add mypy overrides to
ignore missing imports for these optional dependencies.

* Fix Copilot review findings: ARIA role, status bar cache, and pulse opacity

- Change #node-table from role="tree" to role="list" and group elements
  from role="treeitem" to role="listitem" (proper ARIA semantics)
- Include currentView and currentFilter.state in renderStatusBar cache key
  so active pill highlight updates when switching views
- Align pulse animation to 0.35 opacity (already applied in CSS)

title Turnstone — Multi-Node Message Routing
skinparam sequenceArrowThickness 1.5
participant "TurnstoneClient" as Client
collections "Redis" as Redis
participant "Bridge-A\n(node_id: nodeA)" as BridgeA
participant "Bridge-B\n(node_id: nodeB)" as BridgeB
participant "Server-A" as ServerA
== Scenario A: New Message — No Workstream Affinity ==
Client -> Redis : RPUSH turnstone:inbound\n{type:"send", message:"...", ws_id:""}
note right of Redis : Shared queue — any bridge can pick up
BridgeA -> Redis : BLPOP [turnstone:inbound:nodeA,\n turnstone:inbound]
Redis --> BridgeA : SendMessage (from shared queue)
BridgeA -> ServerA : POST /api/workstreams/new\n{name:"", auto_approve:false}
ServerA --> BridgeA : {ws_id:"abc12345", name:"ws-abc1"}
BridgeA -> Redis : SET turnstone:ws:abc12345 "nodeA"
note right : Register workstream ownership
BridgeA -> ServerA : GET /api/events?ws_id=abc12345
note right : Start per-WS SSE thread
BridgeA -> Redis : PUBLISH turnstone:events:global\nWorkstreamCreatedEvent
BridgeA -> Redis : PUBLISH turnstone:events:cluster\nClusterStateEvent(ws_id, state:"idle", node_id:"nodeA")
BridgeA -> ServerA : POST /api/send\n{message:"...", ws_id:"abc12345"}
ServerA --> BridgeA : {status:"ok"}
BridgeA -> Redis : PUBLISH turnstone:events:abc12345\nAckEvent(status:"ok")
... SSE events flow: content, tool_result, status, state_change ...
BridgeA -> Redis : PUBLISH turnstone:events:abc12345\nContentEvent, ToolResultEvent, ...
BridgeA -> Redis : PUBLISH turnstone:events:global\nStateChangeEvent(state:"idle")
BridgeA -> Redis : PUBLISH turnstone:events:abc12345\nTurnCompleteEvent
== Scenario B: Directed Message to Specific Node ==
Client -> Redis : RPUSH turnstone:inbound:nodeB\n{type:"send", target_node:"nodeB", ...}
note right : Per-node queue — only nodeB picks up
BridgeB -> Redis : BLPOP [turnstone:inbound:nodeB,\n turnstone:inbound]
Redis --> BridgeB : SendMessage (from per-node queue, priority)
note right of BridgeB : Process locally on nodeB
== Scenario C: Re-routing (Lands on Wrong Node) ==
Client -> Redis : RPUSH turnstone:inbound\n{type:"send", ws_id:"abc12345"}
BridgeB -> Redis : BLPOP [..., turnstone:inbound]
Redis --> BridgeB : SendMessage (ws_id: abc12345)
BridgeB -> Redis : GET turnstone:ws:abc12345
Redis --> BridgeB : "nodeA"
note right of BridgeB : Owner is nodeA, not me — re-route
BridgeB -> Redis : RPUSH turnstone:inbound:nodeA\n(re-routed message)
BridgeA -> Redis : BLPOP [turnstone:inbound:nodeA, ...]
Redis --> BridgeA : SendMessage (from per-node queue)
note right of BridgeA : Process locally — I own this workstream
== Scenario D: Approval via Response Queue ==
BridgeA <- ServerA : SSE: {type:"approve_request", items:[...]}
note right of BridgeA
Bridge checks auto-approve:
1. _ws_auto_approve[ws_id]? → auto
2. All tools in safe set? → auto
(read_file, search, man,
remember, recall, forget)
3. Otherwise → manual approval
end note
BridgeA -> Redis : PUBLISH turnstone:events:abc12345\nApprovalRequestEvent(correlation_id: req_xyz)
Client <- Redis : (subscribed) ApprovalRequestEvent
Client -> Redis : RPUSH turnstone:resp:req_xyz\nApproveMessage(approved:true)
note right : Response queue — bypasses inbound queue
BridgeA -> Redis : BLPOP turnstone:resp:req_xyz\n(spawned approval thread, timeout 300s)
Redis --> BridgeA : ApproveMessage
BridgeA -> ServerA : POST /api/approve\n{approved:true, ws_id:"abc12345"}
== Heartbeat (continuous) ==
BridgeA -> Redis : SET turnstone:node:nodeA\n{server_url, started} EX 60
note right : Every 30s — TTL 60s
BridgeB -> Redis : SET turnstone:node:nodeB\n{server_url, started} EX 60
