<objective>
Generate and apply database migration for the new market pricing tables and columns.

Purpose: [BLOCKING] Schema push — database must match code before any API work can proceed. Without this, TypeScript types pass (from config) but runtime queries fail.
Output: Migration SQL applied to database.

  <read_first>src/db/schema.ts, drizzle.config.ts</read_first>
  <action>
Run Drizzle migration generation and push:

1. Generate migration: `bun run db:generate`
   - This reads src/db/schema.ts and produces a SQL migration file in drizzle-pg/
   - Expected: creates new migration for market_prices table, community_prices table, and new columns on items/thread_candidates

2. Apply migration: `bun run db:push`
   - Applies the generated migration to the PostgreSQL database
   - Verify by checking that the migration was applied without errors

3. Verify tables exist by running a quick query or checking the migration output

Note: Drizzle ORM detected, push command is `bun run db:push` (per project CLAUDE.md). Non-TTY compatible — no interactive prompts expected.
  </action>
  <acceptance_criteria>
    - A new migration SQL file exists in drizzle-pg/ containing CREATE TABLE market_prices
    - A new migration SQL file exists in drizzle-pg/ containing CREATE TABLE community_prices
    - Migration SQL contains ALTER TABLE items ADD COLUMN price_currency
    - Migration SQL contains ALTER TABLE thread_candidates ADD COLUMN found_price_cents
    - `bun run db:push` exits with code 0

## Trust Boundaries

| Boundary | Description |
|----------|-------------|
| None | Schema migration is an internal operation with no external trust boundaries |

## STRIDE Threat Register

| Threat ID | Category | Component | Disposition | Mitigation Plan |
|-----------|----------|-----------|-------------|-----------------|
| T-33-05 | Tampering | migration SQL | accept | Migrations are generated from code and applied by the developer — no external input |
