Five operator-pending + visual text-object pairs, matching upstream
vimwiki:
ah / ih heading section only (stops at any next heading)
aH / iH heading section + sub-tree (stops at same-or-shallower)
al / il list item (line, with / without marker prefix + checkbox)
a\ / i\ table cell (with / without surrounding `|` separators)
ac / ic table column (with / without the header separator row)
Pre-existing `ah` used aH semantics — fixed to match vimwiki: `ah`
now stops at the next heading regardless of level. `aH` is the new
descendants-inclusive variant.
Implementation notes:
- Pure regex; no LSP round-trip. Each helper computes a `(line, col)`
rectangle and drives the selection with feedkeys.
- Operator-pending and visual need different feed sequences. In visual
the previous anchor is sticky, so bounce through `<Esc>` first. In
operator-pending an `<Esc>` would CANCEL the pending operator —
feed the visual keys directly so Vim treats them as the motion.
- Re-exported helpers (`_heading_block`, `_cell_ranges`,
`_current_cell_for_line`, `_table_bounds`) keep the integration
surface testable without going through Vim's visual-mode pipeline,
whose `'<`/`'>` mark semantics fight headless test harnesses.
Tests: 6 new in scripts/test-keymaps.lua — five pure-helper cases
plus one end-to-end `dah` deletion to verify the operator-pending
wiring.
Gates: 421 Rust / 31 Neovim / 12 Vim.
