Keep Markdown tables from swallowing following blocks

[RowletCC]

A table in a job description or resume consumes the next heading, quote, or list when that line contains a pipe. For example, # Benefits | Location immediately after a table becomes two table cells instead of a section heading. The renderer also accepts tables whose header and delimiter rows have different numbers of cells.

Require matching header/delimiter cell counts and stop table-body collection before an existing supported block opener. Alignment and ragged body-row handling retain their existing behavior. This change covers table recognition and termination; escaped pipe handling remains in the separately submitted PR #150.

Validation: seven independent behavioral checks pass after the fix; the same checks fail in five places on unchanged master. All three focused table tests pass. TypeScript type checking (tsc -p tsconfig.json --noEmit) and npm run build pass. Preservation checks cover alignment, missing and extra body cells, and block-like text inside explicit table cells.

Reference: GFM tables, examples 201 and 203–204.
