When last_context (the preceding markdown text) is very long, the generated image filename exceeds the OS 255-byte limit and os.rename fails with OSError ENAMETOOLONG. Truncate to 60 chars after sanitization.

LGTM — real filename-too-long fix; context is cosmetic. Follow-up will unify the truncate length with table asset naming (80).

* fix: share one 80-char cap for image and table asset filenames Unify the post-#236 image context truncate with table header naming so cosmetic asset stems use a single MAX_ASSET_FILE_NAME_CHARS constant.

What
When
last_context(the markdown text preceding an image) is very long, the generated image filename exceeds the OS 255-byte limit, causingos.renameto fail withOSError: [Errno 36] File name too long.Error
Fix
Truncate
image_name_contextto 60 characters after sanitization inbuild_markdown_image_name(). The context is cosmetic (used in the filename for debuggability), so truncation has no functional impact.Verification
Tested end-to-end with a 44-page PDF that triggered the original error — parsing succeeds after this fix.
