feat(waybar): combined power menu on the battery + profile icons

Item 36(b). Adds `nomarchy-menu powermgmt` — one flat rofi menu of power
Profile rows (→ powerprofilesctl set) + Charge limit rows (→ the same
theme-sync writer batterylimit uses), each half self-gating on its
hardware. No backend duplication; Custom charge stays in the dedicated
batterylimit picker.

Opened two ways (Bernardo's call): the Waybar battery icon AND the
power-profile icon — the profile icon's click flips from cycle → menu.
Wired in waybar.nix and all four whole-swaps (parity). Named `powermgmt`
to avoid the whole-swaps' existing `custom/powermenu` shutdown button
(→ nomarchy-menu power), which is left untouched. The granular System ▸
Power profile / Battery limit rows stay ("keep both").
nomarchy-powerprofile-cycle kept as a standalone bin, now unbound by
default.

Verified: V0 green; V1 HM built (bash -n) — powermgmt case ships, the
generated waybar-config.json wires both icons (2 hits), all four jsoncs
re-wired and still parse, shutdown buttons intact. Click→menu→apply is
V3 (queued).

+  **power-profile** icon (the profile icon's click flips from cycle → menu).
+- **Did:** New `nomarchy-menu powermgmt` (rofi.nix): a flat list of Profile
