docs(roadmap): mark snapshot store, hashes, error scheme, date codec landed

[wmadden-electric]

Linked issue

n/a — docs-only refresh of the RC1 roadmap.

Summary

Brings ROADMAP.md and ROADMAP.html up to date with what landed on main since the July 21 revision. Five task items flip to Landed and one moves to In flight, with the header tallies, per-requirement minibars, and Recently landed list recomputed to match.

Status changes (each verified against a merged PR on main):

Item	Requirement	Was	Now	Evidence
Store each contract snapshot once + fold ref-paired snapshots	3	Open	✅ Landed	TML-3059 #1018, TML-3072 #1024
Hashes lose their sha256: prefix	3	Open	✅ Landed	TML-2756 #1033
One error-code scheme instead of four	3	In review	✅ Landed	TML-3067/3070/3075, reference page TML-3071 #1027
date columns fail through relation-loading	1	Open	✅ Landed	TML-3086 #1038
Scalar-type unification (text only; @db.* deletion still pending)	2	In flight	In flight	TML-2986 #1022
Port Prisma 7 edge-case tests	4	Open	⏳ In flight	#1035 (488 accounted)

Header moves from 1 done / 12 in flight / 21 not started to 5 / 12 / 17; requirement 3 is now three of five done.

Testing performed

n/a — Markdown + standalone HTML. Verified the two artifacts stay in sync: MD status markers count 5 ✅ / 12 ⏳ / 17 ⬜, HTML carries 5 matching Landed pills, and the header bar / minibar counts and widths were recomputed by hand to match.

Skill update

n/a — docs only.
