Ports the write path of io/specctra/SesWriter.java to emit a valid session from a parsed DsnBoard plus a RoutingResult. Each _write_* function mirrors a write* method upstream: - session scope with base_design, placement (resolution + components echoed from the DSN), an empty was_is, and routes - routes carries resolution, a reduced parser scope, library_out with the via padstacks, and network_out - network_out emits (net (wire (path layer width x1 y1 ...)) (via padstack x y)) for each routed net; integer coordinates via round- half-up to match Java Math.round write_ses(board) with no result produces a valid no-op session, proving the DSN-in / SES-out round trip. Only routes > network_out is required by SesReader and kicad-cli; the rest is echoed for a well-formed file. 18 tests: indent/quoting rules, no-op session structure, placement and library_out echo, routed wire/via serialization, integer rounding, and round-trips re-parsed through the project's own DSN tokenizer/sexp (64 tests total across the suite, all green; ruff clean).
