Backspacing from the start of the line after a collapsed `[Pasted text #N]` placeholder deleted the whole placeholder instead of just joining the lines. `_find_placeholder_span` treated any whitespace immediately following a token as an auto-inserted trailing separator, but `str.isspace()` also matches a newline. Restrict that branch to a literal space so a line break falls through to the default backspace, which removes only the newline and leaves the cursor at the end of the placeholder line.

…angchain-ai#4757) Fixed the `dcode` chat input deleting a collapsed `[Pasted text #N]` (or `[image N]`) placeholder when backspacing the line break on the line below it; the line break is now removed while the placeholder is preserved. --- In the `dcode` chat input, pasting large text collapses it into a `[Pasted text #N]` placeholder. Pressing Enter to add a newline and then backspacing from the start of that new line deleted the entire placeholder instead of just rejoining the lines. The cause is in `_find_placeholder_span`: its backwards-delete branch treats any whitespace immediately after a placeholder as an auto-inserted trailing separator and swallows the whole token with it. Since `str.isspace()` also matches a newline, backspacing a line break below a placeholder removed the placeholder. Restricting that branch to a literal space (the separator actually auto-inserted after media placeholders) lets a newline fall through to the default backspace, which removes only the line break and leaves the cursor at the end of the placeholder line. The same fix is applied to the shared base text area used by the inline prompts.
