browser/interfaces: add logprobs

[ParthSareen]

Adds JS SDK support for: ollama/ollama#12899

[BruceMacD]

I think we can remove the logprobs-generate.ts example since the code is largely the same as chat.

[BruceMacD]

We should add these fields in the README also

[ParthSareen]

good callout! will add

Suggested change

	import { Ollama } from 'ollama';
	function printLogprobs(entries: Array<{ token: string; logprob: number; top_logprobs?: typeof entries }>, label: string) {
	console.log(`\n${label}:`)
	for (const entry of entries) {
	console.log(` token=${entry.token.padEnd(12)} logprob=${entry.logprob.toFixed(3)}`)
	for (const alt of entry.top_logprobs ?? []) {
	console.log(` alt -> ${alt.token.padEnd(12)} (${alt.logprob.toFixed(3)})`)
	}
	}
	}
	import { Ollama, type Logprob } from 'ollama';
	function printLogprobs(entries: Logprob[], label: string) {
	console.log(`\n${label}:`)
	for (const entry of entries) {
	console.log(` token=${entry.token.padEnd(12)} logprob=${entry.logprob.toFixed(3)}`)
	for (const alt of entry.top_logprobs ?? []) {
	console.log(` alt -> ${alt.token.padEnd(12)} (${alt.logprob.toFixed(3)})`)
	}
	}
	}
