fix(vscode): sync Agent Manager inspector width

[marius-kilocode]

The Agent Manager terminal and diff viewer currently maintain separate inspector widths, so switching between them moves the divider and produces inconsistent layouts. The divider position is also lost when the webview is recreated.

This change gives both views one shared inspector width, restores it from webview state, and constrains the saved value to the available viewport. Resizing either view now keeps the same position for the other view and across panel reloads. The shared minimum stays 360px on normal layouts; on narrow viewports the effective bounds scale down so the inspector cannot consume the entire editor.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Incremental review of commits since e227378. The previous suggestion is resolved: minPanelWidth(viewport) now scales the minimum down on narrow viewports (50% of viewport, capped at 360px), maxPanelWidth floors at the dynamic minimum instead of 360px, and the PR description explicitly documents the shared 360px minimum on normal layouts. Bounds stay consistent (min <= max for all viewport sizes), the new tests exercise the real implementation, and no memory-leak surface was introduced (pure functions only, no new listeners or subscriptions).

File	Line	Issue
packages/kilo-vscode/webview-ui/agent-manager/AgentManagerApp.tsx	2639	Shared width raises the diff inspector minimum from 200px to 360px, and the maxPanelWidth floor locks the panel at 360px on viewports narrower than ~450px

The width unification itself is clean: removed identifiers have no leftover references, the persisted value is clamped against the current viewport on restore, persistence is debounced and cleaned up, and the changeset is present with user-facing wording. No memory-leak surface introduced.
