Follow-up on @fortun8te's user-made roster sections:
- Sections start empty: no seeded General/Workforce/Clients. With no
sections created the roster renders exactly as before.
- New section and Rename go through one Dialog + Input + Cancel/Save
(the app's session-rename shape) instead of an inline caret; the row
menu's "New section…" files the bot as it creates.
- Delete needs no confirmation: bots return to Unassigned and the toast
offers Undo (restores the section in its slot and refiles its bots).
- Drag: single-row drag under a private MIME type, every valid target
shows a faint outline while a drag is live, the hovered target lights
up, the source section refuses the drop, Escape cancels, and the moved
row no longer stays faded after it remounts under its new section.
- Multi-select (cmd/shift-click, querySelectorAll shift-range) dropped:
the roster has no selection model. Per-bot saveBotMeta writes run in
sequence, one per profile (membership IS a field on each profile).
- Section heading reuses RosterSectionHeader (gains `action` /
`onDoubleClick`), so user sections fold and look like the gateway
headings; ⋯ menu and right-click drive the same Rename / Move up /
Move down / Delete. Empty sections show a dashed "Drag bots here" slot.
- Composes with gateway buckets: sections nest INSIDE each connection
bucket, indented under a hairline rail (membership lives in the bot's
profile on that gateway); empty sections repeat there only mid-drag.
- Full i18n parity (en / ja / zh / zh-hant) for every new string; icon
toggle and the storage-async plumbing removed.
- Tests trimmed to the three invariants (membership persists through
saveBotMeta + reload, remainder = Unassigned, delete returns bots +
undo) plus a live Electron e2e covering the whole flow.
