Patch series "lib/bootconfig: three bug fixes", v2.

Three fixes for lib/bootconfig.c:

1. Fix off-by-one in xbc_verify_tree() unclosed brace error reporting.

2. Check bounds before writing in __xbc_open_brace() to prevent potential out-of-bounds writes.

3. Fix snprintf truncation check in xbc_node_compose_key_after().

This patch (of 3):

__xbc_open_brace() pushes entries with post-increment (open_brace[brace_index++]), so brace_index always points one past the last valid entry. xbc_verify_tree() reads open_brace[brace_index] to report which brace is unclosed, but this is one past the last pushed entry and contains stale/zero data, causing the error message to reference the wrong node.

Use open_brace[brace_index - 1] to correctly identify the unclosed brace. brace_index is known to be > 0 here since we are inside the if (brace_index) guard.
