Add missing friendly names for 14 tools

[Copilot]

Several detected tools lacked friendly display names in src/toolNames.json, causing them to render as raw identifiers in the UI.

Added mappings for all 14 unknown tools:

• Coding agents: bash, claude-code, copilot-cloud-agent, copilotcli
• VS Code internals: github.copilot.default, github.copilot.workspace, vscode_editFile_internal, vscode_fetchWebPage_internal
• File/search: glob, grep, read, write
• Other: kill_terminal, webfetch
