Schema v5 stores each distinct drawing package once in drawing_packages,
keyed by SHA-256; revisions point at it, so details, settings, archive and
restore revisions add no blob. The v4 drawing tables are replaced outright
(no production library existed); nest tables are untouched.
Nesting settings (cut first, priority, rotation constraints, color) become
structured record fields (DrawingLibraryRecord.Settings), returned on every
read, filterable by cutFirst, editable through the metadata endpoint and
applied by LibraryDrawingInsert. Canonical packages now leave every
record-owned field at its default, so renaming or changing settings never
changes the package hash. Saving a nest drawing to the library carries its
settings into the record.
The desktop library browser gains a Cut first column and an Edit Settings
dialog that saves notes and settings as a new revision with the same package.

Two remaining pin rules from the drawing library plan:
- D3: a library drawing added to a nest whose material, grade or
thickness differ from the library record now really arrives without
its cut pins. The insert already warned and reported KeepPins = false;
it now clears the copy's pins, because they were authored for the
library material and thickness. The library link still records the
revision the copy came from.
- A copy of a placement (Clone, CloneAtOffset) keeps its drawing pins
off, so copying or patterning an overridden part does not silently
bring the drawing's pins back. Clearing lead-ins keeps it too: pins-off
is a placement choice, not lead-in state.

Adding a library drawing to a nest has several outcomes that must be decided
before anything changes, so the desktop can show warnings first and so every
rule is tested on Linux. `LibraryDrawingInsert.Plan` returns a new exact copy
carrying its library link, an added quantity on the copy already there, or a
refusal that leaves the nest untouched.
- Material, grade or thickness that differ from the nest still add the drawing
but drop its cut pins, with one warning naming each difference (D3). Names
compare by SharedListNames key and thickness at four decimals, matching the
server's own filters.
- Different units are refused: conversion is out of scope and a silent unit
mismatch would scale the part.
- The same revision from the same server only raises the quantity; a different
revision of that drawing is refused in favour of Update Drawings (D2b).
- Another drawing with the same name is refused naming both, because the
name-keyed DrawingCollection would otherwise drop one silently.
- A package whose hash or units disagree with its record is refused.
