P1 - Reject single oversized subtrees in batch insert (docx-batch-insert.ts):
A first-level block whose descendant count exceeds BATCH_SIZE (1000) cannot
be split atomically (e.g. a very large table). Previously such a block was
silently added to the current batch and sent as an oversized request,
violating the API limit. Now throws a descriptive error so callers know to
reduce the content size.
P2 - Preserve unmatched brackets in color markup parser (docx-color-text.ts):
Text like 'Revenue [Q1] up' contains a bracket pair with no matching '[/...]'
closer. The original regex dropped the '[' character in this case, silently
corrupting the text. Fixed by appending '|\[' to the plain-text alternative
so any '[' that does not open a complete tag is captured as literal text.
