PVC lab: instrument list with estimates, and cost it

quality-automation.md: the day-one per-lot tier becomes a table with an
instrument class and a rough price per check (moisture analyzer, strip
oven, density balance, spectrophotometer, gloss, sieves, muffle furnace,
stereo microscope), plus what was missing: a lab plaque press or two-roll
mill so speck, color and DSC tests do not tie up a production press;
sample conditioning as part of the method at 60 to 90 % ambient humidity;
magnets for metal in lots and regrind. Day-one tier ~USD 55k to 150k
(estimate); Karl Fischer and the ISO 182 Thermomat as options. Mature tier
priced (~120k to 240k), handheld XRF as an option, and partner labs (Payap
pharmacy, CMU science) to defer it.

total-investment.md: the day-one tier goes into "Added scope, not yet in
the roll-up" (55k to 150k USD, 1.8M to 5.0M THB); added total now ~290k
to 690k USD, about 7 to 9 % on the subtotal. Headline total unchanged.
