Replace ts-rs with typeshare for type generation

[antont]

Summary

• Switch from ts-rs to typeshare (by 1Password) for generating TypeScript types from Rust structs
• Replaces the cargo test export_bindings hack with a clean CLI tool that parses source files directly
• Consolidates per-type .ts files into a single generated types.ts

What changed

File	Change
Cargo.toml	ts-rs → typeshare dependency
src/models.rs	#[derive(TS)] + #[ts(export)] → #[typeshare]; counts i64 → i32
src/handlers.rs	Cast query counts as i32 for the new field type
scripts/generate-types.sh	cargo test → typeshare CLI
scripts/check-types.sh	Updated to diff single file
web/src/types/generated/	4 per-type files → single types.ts + barrel index.ts
README.md, AGENTS.md	Updated docs and gotchas

Notable behavioral differences

• interface vs type: typeshare generates export interface Foo { ... } instead of export type Foo = { ... } — functionally equivalent for plain data shapes
• Option<T>: maps to field?: T (optional) instead of field: T | null — the frontend api.ts already converts undefined → null before sending JSON
• i64 unsupported: typeshare rejects i64 (JSON precision concerns), so counts use i32 which is more than sufficient for todo counts

Test plan

• cargo build --no-default-features --features sqlite compiles
• cargo test --no-default-features --features sqlite passes (3/3)
• typeshare ./src --lang=typescript generates correct output
• npx tsc --noEmit — TypeScript compiles with new types
• scripts/generate-types.sh works
• scripts/check-types.sh passes

Note

Medium Risk
Switches the Rust↔TypeScript type generation tool and changes generated type shapes (notably Option<T> now becomes optional fields and counts move to i32), which can surface subtle contract mismatches if regeneration or callers lag behind.

Overview
Replaces the Rust→TypeScript type bridge from ts-rs to typeshare, updating Rust annotations (#[ts(export)]/TS → #[typeshare]), build dependencies, and docs.

Updates type generation scripts to run the typeshare CLI and consolidates frontend generated output from per-type files into a single web/src/types/generated/types.ts with a simplified barrel export.

Adjusts API model types for typeshare limitations by changing todo count fields from i64 to i32 and casting query results in list_todos accordingly; the generated TS types now represent Option<T> as optional properties rather than null unions.
