Minor Changes

#15792 479e1e8 Thanks @flakey5! - Configure SSH for experimental Durable Object-managed Containers
Set containers[].ssh and containers[].authorized_keys when using scheduling_policy: "durable_object". These are application-wide settings that follow the same rules as the existing Durable Object-managed Container settings: normal deployments create missing applications and update explicitly configured values, while omitted settings preserve the existing application configuration.
```
// wrangler.jsonc
{
  "containers": [
    {
      "name": "sandbox",
      "class_name": "Sandbox",
      "scheduling_policy": "durable_object",
      "ssh": { "enabled": true },
      "authorized_keys": [
        { "name": "laptop", "public_key": "ssh-ed25519 AAAA..." }
      ]
    }
  ]
}
```
#15786 bdda4c3 Thanks @ThomasRubini! - Support UDP connect handlers in local development
The experimental connect configuration now accepts protocol: "udp", with optional idle_timeout_ms and max_pending_bytes settings. UDP datagrams are delivered to the Worker's connect() handler using workerd's value-mode socket streams, and can be tested with Miniflare#dispatchConnect({ protocol: "udp" }).
#15779 fc3cbaa Thanks @Naapperas! - Support workflow entries in the exports configuration map
A Worker can now declare the Workflows it defines in exports, keyed by the WorkflowEntrypoint class name:
```
{
  "exports": {
    "MyWorkflow": {
      "type": "workflow",
      "name": "my-workflow",
      "limits": { "steps": 100 },
      "schedules": "0 * * * *"
    }
  }
}
```
A workflow export accepts the same settings as a workflows binding: limits, concurrency, schedules, and default_retention. wrangler deploy and wrangler versions upload send these entries to the upload API by name, and wrangler deploy and wrangler triggers deploy provision the Workflow with its settings, just as they do for workflows bindings owned by the Worker. A Workflow may be declared both as a binding and as an export, as long as both declarations use the same class and do not set the same setting to different values. A binding to another Worker's Workflow cannot share a name with an export. @cloudflare/config adds the matching exports.workflow() helper. Local development does not yet act on these entries.

Patch Changes

#15838 15799d4 Thanks @oddharsh! - Update smol-toml to 1.9.0 to fix slow parsing of very large TOML files
Parse time for TOML config files now grows linearly with their size, instead of with its square: a 40,000-line file that took 259 ms to parse now takes 17 ms, while typical wrangler.toml files parse in the same time as before. This addresses the GHSA-r4xh-jqrq-34v2 advisory against earlier versions of the parser.
Some TOML syntax errors now point at the character that caused them. For example, a wrangler.toml containing INVALID "FILE is now reported as illegal character in key at the ", rather than incomplete key-value at the start of the line.
