The marmot harness surfaced the bug on first run: amy stripped `marmot group create --name "Interop-02"` thinking the global account selector ran into the group's display-name flag. Result: amy resolved the "Interop-02" account, found no identity.json, and errored — no group ever got created. Renames the global account-selector flag to `--account`. The per- subcommand `--name` flags (`marmot group create --name "Demo"`, `profile edit --name "Alice"`, `marmot await group --name X`) are untouched — they're free of the global parser now that it doesn't claim the same name. Sweep: - `Main.kt`: GlobalFlag.NAME → ACCOUNT, long "--account". - `Config.kt`: DataDir.resolve param renamed nameFlag → accountFlag; every error message points the user at --account. - `UseCommand.kt`: error hint says `amy --account NAME init`. - All test wrappers + direct $AMY_BIN calls under cli/tests/ swap the global `--name X` for `--account X` (subcommand --name kept exactly where it appeared). - README + DEVELOPMENT updated.
