Same fix as the agent schema commit — zod 3.25 (resolved by ^3.25.0)
requires z.record() to take both key and value schemas. The single-arg
form is v4 syntax.
Fixed 15 remaining call sites across canvas, project, report, common,
webhook, habit, task, note, and milestone schemas. Pure type-only fix —
runtime behavior identical.
zod 3.25 (the version resolved by ^3.25.0) requires z.record() to take
both a key and a value schema. The single-arg form z.record(z.unknown())
is zod v4 syntax, which trips next build's typecheck.
Four call sites in packages/shared/src/schemas/agent.ts were written in
v4 form (lines 39, 41, 73, 74). This is a pure type-only fix — runtime
behavior is identical.
