feat(agents): open AGENTS.md editor in a modal, as a settings row, with section reordering

Move the AGENTS.md section editing into a click-to-open modal so the Basic
tab no longer expands the full document inline. Present the entry as a
settings-style row (title + description on the left, a "manage" button on the
right) instead of stacked label/hint/button.

Add optional move-up/move-down controls to MemorySection (off by default, so
MemoryBrowser is unaffected) and wire reordering in AgentGuideEditor: adjacent
sections swap and the whole file is re-saved, with a synthetic preamble pinned
to the top.
