docs(readme): shorten the local-testing tunnel notes - #556
Merged

Conversation
The paragraph after the local-testing example had grown into a wall of transport and retry internals. Keep what a first-time reader needs (what --local saves, picking a host, slow dev servers, TLS behind a re-signing proxy, the 60-second connect limit, cancellation and refunds, plan authoring, Portal runs) and leave the rest to DOCUMENTATION.md, which already covers it.

- Line 157: Update the README description of `--local <port>` to state that
`localhost` is the default and that `--local-host` remains available to override
the saved host; retain the existing guidance about explicit `--url` values.
- Line 159: Update the README sentence to qualify that tunnels use verified TLS
when the server advertises a TLS endpoint, while older or self-hosted servers
without one use the legacy plaintext data port. Keep the existing CA guidance
and timeout behavior unchanged.

| An owned tunnel's timeout or Ctrl-C cancels unfinished runs by default. A borrowed run still detaches without cancellation on Ctrl-C/SIGTERM because its owner keeps the tunnel alive; if that owner disappears while a run is active, the borrower cancels its own run and reports `cancelled`, `already finished`, or `skipped`. A run cancelled before it finishes is refunded. `--no-cancel-on-interrupt` also skips this owner-gone cancellation. Keep the early stderr run-id receipts (`Run <runId>` for one test, `[i/N] <testId> → run <runId>` for a batch) and read the reported runs before re-running. | ||
| Local projects skip exploration/plan generation; author plans with `test create --plan-from`. Portal runs are blocked for free until you set a public project URL. | ||
| See [the full local-testing reference](./DOCUMENTATION.md#local-frontend-testing-and-tunnels) for flags, login, billing/refunds, timeouts, and retargeting. | ||
| `--local <port>` saves new project and environment URLs as `http://localhost:<port>`. Use `--url http://127.0.0.1:<port>` or `--url http://[::1]:<port>` when the host matters (`--local-host` is deprecated). Dev servers can be slow through a tunnel, so for heavy apps test a production build (`npm run build` plus your framework's preview or start command). |

| The tunnel uses verified TLS. On a network that re-signs TLS, set `NODE_EXTRA_CA_CERTS=/path/to/ca.pem` to your organisation's root CA. If the tunnel keeps failing to connect for 60 seconds, the command exits **10**, and an owned run is cancelled and refunded. |

Qualify the TLS guarantee.
Older or self-hosted servers that do not advertise a TLS endpoint use the legacy plaintext data port. Update this sentence so it does not imply that every supported tunnel connection is encrypted.

The notes under the README's local-testing example had grown into one wall of transport and retry internals: host-resolution rules, the TLS trust store, retry-episode timing, plaintext fallback and borrowed-tunnel edge cases (about 3,200 characters). This trims them to what a first-time reader needs (about 1,100 characters):
--local <port>saves, how to pick a different loopback host, and that--local-hostis deprecated;NODE_EXTRA_CA_CERTSon a network that re-signs TLS;Everything removed is already covered in DOCUMENTATION.md → Local frontend testing and tunnels, which the README links to. README only; no behaviour change.
