stream() computes default pageSize before ready(), which can break live streaming

[cybito]

Hi, I found a live-streaming issue in PineTS 0.9.7.

stream() computes the default pageSize before await this.ready():

const pageSize = options.pageSize || this.data.length;

At that point this.data.length can still be 0, so pageSize becomes 0 and is never recomputed later.

This can break _runPaginated() / live streaming behavior:

• ctx.idx may stay at 0
• ctx.marketData[ctx.idx] may point to an old historical candle instead of the latest candle
• the historical/live branch in stream() can misclassify the current candle
• in practice this caused repeated processing of the same candle, no bar progression, and in some runs a hot loop with very high CPU usage

Relevant code:

• src/PineTS.class.ts: stream()
• src/PineTS.class.ts: _runPaginated()

Suggested fix:

• compute the fallback pageSize after await this.ready(), or
• lazily resolve the default from the loaded data before calling _runPaginated()

Workaround on the consumer side:

• pass an explicit pageSize to stream()

I can provide a minimal repro if helpful.

Thank you for reporting this @cybito it's clearly a bug :)
I'll include a fix in the next release
