- Replaced hardcoded box-shadow values with new CSS variables for consistency and improved theming.
- Updated styles in postEditWidget, findOptionsWidget, findWidget, floatingMenu, hover, parameterHints, peekViewWidget, renameWidget, stickyScroll, suggest, actionWidget, hover, quickInput, agentFeedback components, and more.
- Introduced new shadow variables: --vscode-shadow-sm, --vscode-shadow-md, --vscode-shadow-lg, --vscode-shadow-xl, and --vscode-shadow-hover for better control over shadow effects.

* sessions: always show Logs panel in sessions window
The Logs/Output panel was previously gated behind dev mode only.
Make it always visible so MCP gateway negotiation logs and other
output channels are accessible for debugging.
* sessions: mcp protocol negotiation, gateway output channel, and customizations UI improvements
MCP Gateway Protocol Negotiation:
- Gateway now negotiates protocol version with clients instead of
hardcoding '2025-11-25', fixing compatibility with older SDK versions
- Adds MCP_SUPPORTED_PROTOCOL_VERSIONS covering all known MCP spec versions
- Responds with client's requested version if supported, falls back to latest
- Logs client info and negotiated version for diagnostics
- 7 new unit tests covering all negotiation scenarios
MCP Gateway Output Channel:
- Dedicated 'MCP Gateway' output channel via ILoggerService (logLevel: always)
- Gateway service and sessions now use ILogger instead of ILogService
- All gateway lifecycle events visible in Output panel
Sessions Window MCP Integration:
- Re-enable MCP Servers section in sessions management editor
- Add MCP Servers to sessions sidebar toolbar with total count
- Add MCP Servers link item in sessions tree view (navigates to editor)
- Add MCP Servers to sessions overview view with count from IMcpService
- Add chat.experimentalSessionsWindowOverride setting for sessions-specific
extension behavior (overridden to true in sessions defaults)
MCP List Widget Polish:
- Add 'Built-in' group showing extension-provided servers (e.g. GitHub MCP)
- Remove per-item server icons, aligning with other customization sections
- Hide running/stopped status indicators in sessions window
- Match item height (36px), padding, and font styling to other sections
- Hide empty description lines to tighten layout
Customizations UI Cleanup:
- Remove git status badges and SCM service dependency from list widget
- Remove per-item storage badge icons (workspace/user/extension)
- Remove 'Developer: Customizations Debug' command (replaced by output channel)
- Simplify sidebar counts to single total number (no category icon badges)
- Remove group separator borders, use spacing only
- Fix list container overflow (hidden -> auto) and add min-height: 0 for scroll
- Fix layout() fallback from 100px to 0px with requestAnimationFrame re-measure
Customizations Debug Output Channel:
- New sessions-only 'Customizations Debug' output channel
- Streams snapshot on every change: summary table + search paths + file details
- Includes MCP server listing with connection states
Hooks Count Fix:
- Toolbar hook counts now match management editor (per-hook, not per-file)
- Uses IFileService to parse hook JSON files and count individual hooks
The MCP gateway now negotiates the protocol version with connecting
clients instead of hardcoding 2025-11-25. This fixes compatibility
with clients using older @modelcontextprotocol/sdk versions that
do not support the latest protocol version.
* address PR review feedback
- Fix stale MCP count in overview: use autorun to watch mcpService.servers
- Guard rAF layout callbacks against widget disposal
- Make built-in MCP items non-interactive (no pointer cursor, no hover)
- Fix _logSnapshot dropping events: re-run if dirty during snapshot
- Add CSS for mcp-builtin-readonly items
