revert(cli): undo Bedrock buffer pin

[chrarnoldus]

Reverts the dependency and lockfile changes from #11968 because the Bedrock fix has been superseded by #12079.\n\nThe changeset from #11968 is intentionally not included in this revert; it was already consumed by release v7.4.2.

CRITICAL

File	Line	Issue
package.json	144	Removing the @smithy/util-buffer-from override lets it resolve back to 4.3.6, the version that caused Bedrock requests to silently return empty output on HTTP 200 (fixed in #11968). No accompanying fix for the root cause was found in this diff or recent history.

WARNING

File	Line	Issue
bun.lock	1936	Lockfile now resolves @smithy/util-buffer-from@4.3.6, confirming the regression risk described in the package.json comment.
