v0.3.4

⚠️ Breaking: a regenerated imperative --script now writes <stem>.pdf by default (was SVG+DXF via the legacy tuple), and its script variables changed from svg_path, dxf_path to a paths dict — aligning the imperative flavour with the Sheet flavour and the direct CLI. Migration: regenerate with --format svg,dxf to keep the old outputs. Previously-generated scripts are unaffected (#709).

Direct ↔ generated-script parity

Generated scripts now faithfully reconstruct the direct CLI drawing:

• Side-drilled hole location dims (#426/#133) and rotational furniture (#426/#424)
• finalize() now resolves queued detail views (#661)
• Emitted-Sheet fidelity locked with a real fixture (#707)
• --format now reaches --script output (#709)

Added

• .thread("M3x0.5") — first-class tap/thread callout folded onto the hole leader; .thread(...).finish(...) gives Ra-on-thread (#764)
• .knurl("0.8") — knurl callout (#765)
• Title-block fields — material / date / revision / company, across the API, CLI, and the Sheet-script round-trip (#766)
• Object-reference script workflow — docs + an inline tip for live-source inputs (#770/#771)
• Solve-trace / explain mode (#736)

Fixed

• _largest_empty_rect O(N⁴) hot spot — ~85× faster on crowded detail views (#661)
• Pin/provenance-safe detail-view height demotion (#661)
• Y-turned stepped-shaft crash (#661)
• Boss heights modeled, rendered, and coverage-checked (#632)
• Authored tolerances render for chamfer/fillet/flat/groove/pocket/plate/slot (#724/#698)
• CTC-02/04 no longer drop step-height / overall-height dims (#733)

Deprecated

• The seven Drawing compat aliases; draftwright.sheet_dsl
