fix: encode large copy payload metadata in chunks (#12847)

## Summary

Fix Ctrl+C copy for large subgraphs by encoding clipboard metadata in
bounded byte chunks instead of spreading the full serialized payload
into a single `String.fromCharCode(...)` call.

## Root Cause

<img width="648" height="33" alt="스크린샷 2026-06-15 오후 4 46 52"
src="https://github.com/user-attachments/assets/09aec159-fd10-4979-bfb2-51aec9b51a63"
/>

Ctrl+C uses the native `copy` event path in `useCopy.ts` so ComfyUI can
write serialized node metadata into the system clipboard as `text/html`.
That metadata supports the cross-app / cross-window copy-paste path.

For Unicode safety, the current code first converts the serialized node
JSON to UTF-8 bytes with `TextEncoder`, then converts those bytes into a
binary string for `btoa`. The bug was in this conversion step:

```ts
String.fromCharCode(...Array.from(new TextEncoder().encode(serializedData)))
```

When a selected subgraph is large enough, the UTF-8 byte array becomes
too large to spread as function arguments. The browser throws
`RangeError: Maximum call stack size exceeded` before clipboard metadata
is written, so Ctrl+C appears to fail for large subgraphs.

The right-click / menu copy path was not affected in the same way
because it uses LiteGraph's internal `copyToClipboard()` path directly
and does not go through this system clipboard metadata encoding step.

## Changes

- **What**: Convert UTF-8 bytes to a binary string in `0x8000` byte
chunks before passing the result to `btoa`.
- **Why**: This preserves the existing UTF-8 safe cross-app clipboard
metadata format while avoiding the JavaScript argument-count limit that
caused the stack overflow.
- **Fallback**: Wrap system clipboard metadata encoding/writing in
`try/catch` so the internal `canvas.copyToClipboard()` result is still
produced even if the metadata bridge fails unexpectedly.
- **Dependencies**: None

## Review Focus

- Chunking is only used while building the binary string for base64
encoding. The clipboard payload format remains unchanged.
- Multi-byte UTF-8 data remains safe because chunking happens at the
byte-string construction layer; paste still reassembles the full byte
stream before `TextDecoder` decodes it.
- The unit test exercises the actual `useCopy` copy handler with a large
serialized payload, Unicode metadata, and a partial final chunk.

## Test Plan

- `vitest run src/composables/useCopy.test.ts`
- pre-commit hook: `oxfmt`, `oxlint`, `eslint`, `typecheck`
- pre-push hook: `pnpm knip`

No E2E was added because this regression is isolated to deterministic
clipboard metadata encoding in `useCopy`. The unit test exercises the
actual `copy` event handler with a large serialized payload and Unicode
metadata, avoiding a large workflow fixture and slower browser coverage
for behavior that does not require canvas rendering or end-to-end UI
orchestration.
