feat(core,cli): add node-24 and node-26 runtimes, deprecate experimental aliases

Promote node-24 and node-26 to supported runtime options in
trigger.config.ts. The experimental-node-24 and experimental-node-26
names remain as deprecated aliases that resolve to their replacements
and emit a deprecation warning.

+Add `node-24` and `node-26` as supported `runtime` options in `trigger.config.ts`. The `experimental-node-24` and `experimental-node-26` names are now deprecated aliases and emit a deprecation warning; switch to `node-24` / `node-26` instead.
