Add collapsible GitHub Copilot-style tool usage display

[Copilot]

Tool invocations previously rendered fully expanded (name + argument chips + result) on every call, creating visual noise. This adds a compact, collapsible row — [>_] Check maven local repo location ❯ — matching the GitHub Copilot UX pattern, with details hidden until the user expands them.

Changes

• ToolExecutionPane — Rewritten as pure Java (drops NetBeans form editor). Now renders as a collapsed header row by default; clicking anywhere on the row toggles the details section (argument chips + result). ToolExecutionPane.form deleted.

  State	Layout
  Collapsed (default)	[>_] <human-readable name> ❯
  Expanded	Header + ToolInvocationPane argument chips + scrollable result

• StringUtil.camelCaseToHumanReadable() — Converts tool method names for display. Handles camelCase, acronym boundaries, and letter/digit splits:

  • checkMavenLocalRepoLocation → "Check maven local repo location"
  • thisIsATool1 → "This is a tool 1"

• Icons — Added ICON_TERMINAL (>_), ICON_CHEVRON_RIGHT (❯), ICON_CHEVRON_DOWN (⌄).

• ToolExecutionPaneTest — Replaced old always-expanded tests with collapsed-by-default assertions; toggle expand/collapse coverage. Added StringUtilTest for the new conversion logic.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@jGauravGupta I like this improvement! just one suggestion: please do not remove the NB form yet. I use them to have a visual feeling without running code.
