v1.1.0 - origin-plotting skill + origin_help quick-start

v1.1.0: quick-start for AI agents. 1) New origin-plotting skill (DSH native skill mechanism) - installed to DSH skill roots, model loads it on demand and gets the full usage cheat-sheet (data format, 16-tool table, 10 task templates) without reading README. 2) New origin_help MCP tool - instant (1ms) quick-start JSON, no Origin connection needed. 3) register_to_dsh.ps1 now also installs the skill idempotently. 4) Tool descriptions enriched with usage hints. Verified: skill discovered live by harness, mcp-test 17 tools green.

v1.0.1 - science analysis suite (16 MCP tools)

v1.0.1: science analysis suite. New MCP tools (8 -> 16): origin_filter_data, origin_fit (linear + NLFit with Origin built-in functions), origin_plot3d (surface/scatter), origin_stats, origin_transform (smooth/normalize/derivative/interpolate), origin_integrate (AUC), origin_fft (spectrum + peaks), origin_correlate, origin_peak_find, origin_histogram, origin_plot_contour (contour/contour_fill/3d_wire). Plot types: histogram/box/bar + error bars. Fixes: plotxy col range via to_col_range, box via Origin box template, correlate unequal-length truncation, single-instance COM hardening. Tests: science 20/20, advanced 12/12, concurrency 8/8, mcp-test 16 tools.
