…loses #6211) Ports the decisions behind the generated Lean text as pure integer functions: the variable-name sequence with its keyword skips, the plus/minus/zero weight at each chain step, chain lengths, depth parity of the cancellation chain, and the first/last swap of the zero-weight chain. The text assembly (theorem_block, main) stays an undefined body because str + str does not compile in t27. Checked with t27c from this tree and Zig 0.16.0: typecheck OK, spec-status IMPLEMENTED, gen 157 lines with no "not yet implemented", test-report 11/11. Name codes were cross-checked against the original var_names for 66 names. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Closes #6211
Adds
specs/port/scripts/gen_w388_lean.t27, the port ofscripts/gen_w388_lean.py. One file, nothing else.str + strdoes not compile in t27, so the Lean text assembly is not ported. What is ported are the decisions that shape the text, as pure integer functions: the variable-name sequence with its keyword skips (var_names, names packed as ASCII codes), chain lengths (nest_mac,plus_chain,minus_chain), the weight at each step (cancellation_weight,zero_chain_weight), the depth parity ofcancellation_chain,zero_weight_closuresize and the first/last reorder.theorem_blockandmainkeep their names withundefined;bodies (string formatting, file read/write), and no test calls them.Checks from this branch with

The signatures differ from the Python (integers instead of strings and lists), which is the point of the port.
