Adds a "Storm Sewer" ribbon tab backed by a new in-repo `stormsewer` engine crate (vendored under crates/). The engine implements standard public-domain methods — Rational-method peak-flow accumulation, Manning circular-pipe hydraulics, time-of-concentration / IDF intensity, and an HGL backwater pass with junction losses — with 24 unit tests and no external dependencies. Module (src/modules/storm_sewer/): - Drafting: SS_INLET / SS_JUNCTION / SS_OUTFALL place structure markers and SS_PIPE chains pipe runs (interactive CadCommands). - Analysis: SS_ANALYZE / SS_REPORT / SS_PROFILE open a .ssn network file, run the engine, draw the plan and HGL long-section, and print a report. - SVG icons; SS_* commands registered for command-line autocomplete. Integration is additive: build.rs auto-discovers the module and one dispatch block is added to src/app/commands.rs. 7 module integration tests. See src/modules/storm_sewer/INTEGRATION.md for the design and the optional follow-up (drive analysis from canvas geometry via XDATA). Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
