chore(deps): bump relaycast SDKs to latest (#1203)

* chore(deps): bump relaycast SDKs to latest

Upgrade every relaycast SDK dependency to its latest published version:

- npm @relaycast/sdk ^4.1.6 -> ^5.0.5 (v4->v5 major) in packages/sdk + packages/cli
- Rust relaycast crate =5.0.1 -> =5.0.2 in crates/broker
- PyPI relaycast-sdk >=0.2.0 -> >=0.3.0 (communicate + dev extras)
- Swift relaycast git dep 4.2.0 -> 5.0.5

v5 migration: agents.release now returns an action invocation (matching
agents.spawn) instead of the synchronous { name, removed, deleted, reason }
result. The remove_agent MCP tool now surfaces that invocation via jsonResult.

* chore(deps): update Swift Package.resolved to relaycast 5.0.5

Resolves the relaycast git dependency lockfile to tag 5.0.5, matching
the Package.swift constraint bump. swift build + swift test (70 tests)
pass against 5.0.5.

 ### Changed
 
+- relaycast SDKs upgraded to latest: `@relaycast/sdk` 5.0.5 (v4→v5 major), `relaycast` crate 5.0.2, `relaycast-sdk` 0.3.0, Swift relaycast 5.0.5. The v5 `agents.release` now returns an action invocation (like `agents.spawn`); the `remove_agent` MCP tool surfaces that invocation.
 - The hosted engine base URL default is owned solely by the relaycast SDK. `agent-relay`, `agent-relay-broker`, and the bundled SDKs no longer hardcode a base URL — they pass `RELAYCAST_BASE_URL`/`RELAY_BASE_URL` through for self-hosting and otherwise inherit the SDK default (`cast.agentrelay.com`). The broker reaches the fleet node-control endpoint via the SDK's `node_control_ws_url` helper and only injects `RELAY_BASE_URL` into spawned agents when an override is set.
