feat(console): allow multi-sheet autonest with --max-sheets and --stock

Browse Source 
--autonest can now use more than one physical sheet. The first layout
replaces the target plate's parts, further layouts are inserted as new
plates after it, and --stock offers explicit sheet sizes (with optional
costs) built from the target's spacing, quadrant and clamp rail.
NestPipelineCommit gains ApplyToPlates for callers without a
PlateManager. Per-sheet results and overlap checks cover every
committed plate.

## Console and MCP
Console `--autonest` uses the jobs engine named by `--engine` (Default when omitted) against one physical sheet. The selected plate's old parts are replaced only after acceptance; other plates are unchanged. Default demand is still one of each drawing unless `--quantity` is supplied. A partially fulfilled, valid result may be saved; a successful placement is not a claim that all demand was met.
Console `--autonest` uses the jobs engine named by `--engine` (Default when omitted) against one physical sheet unless `--max-sheets <n>` allows more. `--stock WxL[:cost],...` offers those sizes instead of the selected plate's size, each unlimited and built from the selected plate's spacing, quadrant and clamp rail; costs are all-or-none and a cost summary is printed for valid results. The selected plate's old parts are replaced by the first layout only after acceptance, further layouts are inserted as new plates right after it (with its grain and cutting parameters), and other plates are unchanged. Default demand is still one of each drawing unless `--quantity` is supplied. A partially fulfilled, valid result may be saved; a successful placement is not a claim that all demand was met. `--check-overlaps` checks every committed plate.
Invalid output is printed and rejected with exit code 2 without saving or posting. `--allow-invalid` explicitly accepts representable layout violations. Malformed output, multiple returned sheets, and zero placements are never saved by this path. Unknown engines exit 1. `--autonest --keep-parts` rejects an occupied target: use the plain interactive fill path for existing obstacles instead.
Invalid output is printed and rejected with exit code 2 without saving or posting. `--allow-invalid` explicitly accepts representable layout violations. Malformed output, more physical sheets than `--max-sheets`, and zero placements are never saved by this path. `--max-sheets` and `--stock` without `--autonest`, or with malformed values, exit 1 before solving. Unknown engines exit 1. `--autonest --keep-parts` rejects an occupied target: use the plain interactive fill path for existing obstacles instead.
MCP `autonest_plate` requires an empty target. The stdio server serializes all tool calls sharing its mutable session, so another request cannot change drawings or occupy a target during a solve. `allow_invalid` defaults to false. It reports violations and makes no changes on rejection, including with an override when the output is unrepresentable or contains multiple sheets. `engine` defaults to Default, and its description lists the built-in engines with what each suits. Fill tools (`fill_plate`, `fill_area`, `fill_remnants`, `pack_plate`) remain separate and default to the Fill strategy. Console and MCP load jobs plug-ins from `Engines/` beside their executable.
