Kpa-clawbotandopenclaw-bot 28713fabdb feat(map): #1108 hide non-region nodes by default, add 'Show all nodes' toggle (#1501)
Closes #1108

## What
When an operator selects a region on the Live map, default to **hiding**
nodes outside that region. The operator picked the region for a reason —
far-away markers are visual noise. Operators who want the legacy
show-everything behavior can flip the new **Show all nodes** checkbox
next to the region dropdown.

Default: **off (hide non-region nodes)**. State persists in
`localStorage['mc-region-show-all-nodes']`.

## Why
Tracks the request in #1108 — region filtering currently scopes packet
feeds + metrics but the map keeps every node visible, which defeats the
point of selecting a region in the first place.

## How
- `public/region-filter.js`: new `RegionShowAll` module (`get` / `set` /
`onChange` / `STORAGE_KEY`) plus `RegionFilter.nodesRegionQueryString()`
— returns `&region=…` only when a region is selected **and** showAll is
off. Other surfaces (packets, metrics) continue to use the unconditional
`regionQueryString()`.
- `public/live.js`: `loadNodes()` appends `nodesRegionQueryString()`;
region-change and showAll-change handlers reload nodes so markers update
immediately.
- `public/live.css`: aligns the new toggle with the existing
`.live-toggles` rhythm.
- `test-1108-region-hide-nodes.js`: 7 unit assertions covering
default-off, persistence across reloads, set/get, and the conditional
query-string builder.

## TDD trail
- `dbf6d6db` — red test commit (assertion failures, helpers do not exist
yet)
- `eefa1185` — green commit (helpers + wiring)

## CDP validation (staging, after hot-deploy)
| state | markers |
| --- | --- |
| no region | 517 |
| region=SJC, showAll=off | **497** (region-scoped) |
| region=SJC, showAll=on  | 517 (legacy behavior) |

Toggle state survives reload (`RegionShowAll.get() === true` after
refresh).

## Out of scope
- Static `/map` page (`public/map.js`) — its region UI is jump-buttons,
not the shared `RegionFilter` selector. A follow-up could wire
`nodesRegionQueryString` there too, but it's a separate UX surface.
