Developer c8db6ce933 fix: disable native touch panning on mobile terminal and archive specs

- Change mobile terminal CSS to use touch-action: none and
  overscroll-behavior: none so the custom touch handler owns swipes
- Archive completed/partial OpenSpec specs to
  openspec/changes/archive/2026-06-14-completed-specs-archive/
- Regenerate project maps

Quality gates: npm run typecheck, npm run lint (apps/web)

ADDED Requirements

Requirement: Proxy endpoint exists for running instances

The API SHALL expose an endpoint that forwards HTTP requests to a running tool instance.

Scenario: Access running instance

WHEN an authenticated user sends a GET request to /instances/{id}/proxy/
THEN the request is forwarded to the instance's container
AND the response is returned to the user

Scenario: Access instance subpath

WHEN an authenticated user sends a request to /instances/{id}/proxy/api/status
THEN the request is forwarded to {container_url}/api/status
AND the response is returned to the user

Requirement: Only instance owner can access proxy

The proxy endpoint SHALL verify that the authenticated user owns the instance before forwarding.

Scenario: Owner accesses instance

WHEN the instance owner requests /instances/{id}/proxy/
THEN the request is forwarded to the instance

Scenario: Non-owner attempts access

WHEN a user who does not own the instance requests /instances/{id}/proxy/
THEN the API returns 403 Forbidden

Requirement: Proxy handles WebSocket upgrades

The proxy endpoint SHALL support WebSocket upgrade requests for real-time features.

Scenario: WebSocket connection to instance

WHEN a user sends a request with Upgrade: websocket header
THEN the API establishes a bidirectional WebSocket connection to the instance
AND messages are relayed between user and instance

Requirement: Frontend uses proxy URL for instance access

The frontend SHALL link to the proxy endpoint instead of the internal container URL.

Scenario: User clicks Open button

WHEN a user clicks "Open" on a running instance
THEN a new tab opens to /instances/{id}/proxy/
AND the proxied instance content is displayed
