fix: prevent onoutroend from firing twice when compilerOptions.hmr is true (#18655 )

Fixes #18440

`hmr()` in `packages/svelte/src/internal/client/dev/hmr.js` wrapped a
component in a `block` effect containing a `branch` effect. It forwarded
the inner effect's `nodes` object to the outer block:

This shared the same reference, meaning `outer_block.nodes ===
inner_branch.nodes`. When `pause_children` collected transitions for
unmounting, Each collected transition had `out(check)` called multiple times,
starting multiple animations and firing `outroend` multiple times.

Fix by only copying `start`/`end` (the DOM range info the outer block needs)
without sharing the transitions array:
