docs: never build on the Pod, and recover from a missing build

[ng]

Summary

Mirrors the doc changes from sleepypod/core#799 onto the docs site.

• Developers → Core development: adds a "Never build on the Pod" section. It explains why next build on the Pod destroys the installed build, and notes the next.config.mjs guard and the SP_ALLOW_POD_BUILD=1 override. The guard is scoped to "releases that include core#799" because that PR hasn't merged yet.
• Troubleshooting → Core: adds "Web UI down, service restarting in a loop", with a check for server.js, the log signatures for both old and new releases, and sp-update / ./scripts/deploy recovery.

Test plan

• pnpm check: format, media, build, typecheck, and 163/164 browser tests pass. The one failure was a /dial/enclosure click timeout, an unrelated page, and it passes when re-run on its own.
• After deploy, both new anchors resolve: /developers/core/#never-build-on-the-pod and /troubleshooting/core/#web-ui-down-service-restarting-in-a-loop

Summary by CodeRabbit

• Documentation
  • Clarified that developers should build locally and deploy to the Pod, rather than build on the device, where builds can remove the existing web app and exhaust available memory.
  • Documented that supported releases block next build on an installed Pod by default, with an override available.
  • Added troubleshooting steps for a web interface that is unavailable while its service repeatedly restarts, including recovery options using a pre-built release or deployment from a computer.

Merge Risk: 🔵 Low · up to b6de0

The developer guide overstates the restart-loop behavior for newer Core releases, which may mislead troubleshooting. Scope that warning to older releases before merging.
