Add per-wire end coverings and dimensioned strip length; bump to 0.1.4

[shawnpatel]

Wires take endCoverings ({ from|to: { covering, lengthMm } }) so a piece
of heatshrink can be applied to one wire alone at its termination — e.g.
over each solder joint at a connector — instead of sleeving the whole
bundle via a segment covering. Nodes with end-covered wires get a longer
fan-out; sleeves are drawn on each wire's own lead with a callout, added
to the BOM covering totals, and noted in the wire list. Validation rejects
end coverings on jumpers or longer than the wire.

Terminals take stripMm; bare/tinned ends draw a longer exposed conductor
(copper for bare) with a STRIP n mm dimension, and every wire ending at a
terminal with stripMm gets a wire-list note.

Also widens the wire list NOTES column and makes note wrapping conservative
for uppercase text so notes stop running into the title block.

Note

Low Risk
Additive schema and rendering/BOM behavior with validation guards; version bump only affects published packages.

Overview
Adds per-wire endCoverings so heatshrink (or other coverings) can be specified on individual wire terminations instead of only on whole bundle segments. Layout widens fan-out at affected nodes (leadGaps / FANOUT_SLEEVED), SVG draws sleeves on each wire’s lead with callouts, and BOM/wire-list totals and notes include these pieces. Validation blocks end coverings on jumpers or longer than the wire.

Terminals gain optional stripMm: bare/tinned ends show a longer exposed conductor (copper on bare) with a STRIP n mm dimension; all terminal styles get strip notes in the wire list.

Also bumps packages to 0.1.4, widens the wire list NOTES column, and tightens note word-wrap for uppercase text. Docs, skill reference, and the branched battery example demonstrate solder joints with per-pin heatshrink.

End-covering stubs face the wrong side

Medium Severity

Pinless nodes other than diodes and resistors always grow the endCoverings stub in the facesRight direction. A mid-tree splice or breakout therefore draws the sleeve on the parent side even when the covered wire leaves toward a child, so the heatshrink appears on the wrong lead.

Letter notes collide with title block

Medium Severity

Widening the wire-list NOTES column to 190 shrinks the sheet-notes band on Letter to about 8px. Notes wrap to fragments and run into the title block — the overflow this change set out to stop.
