feat: add is_extended_promotional column to all component tables

[usernametooshort]

Closes #92

Summary

Adds is_extended_promotional to all component tables and the base components table.

Changes

• component-base.ts: Added is_extended_promotional: boolean to BaseComponent interface
• 37 derived component tables: Added the column spec and value extraction from json_extract(extra, "$.promotional")
• New optimization component-extended-promotional-column.ts: Adds is_extended_promotional as a SQLite GENERATED ALWAYS AS column on the base components table, with an index

Data Source

The value is derived from extra JSON field: json_extract(extra, "$.promotional"), which is the same source used by jlcparts. This is consistent with how basic and preferred are stored.

Testing

• TypeScript compiles without new errors
• Consistent pattern with existing in_stock and is_basic columns

Inconsistent boolean conversion logic across base and derived tables

The derived tables use Boolean(c.extra && JSON.parse(c.extra).promotional) which treats the string "false" as truthy, while the base table's GENERATED column in component-extended-promotional-column.ts explicitly checks != 'false' to treat it as falsy.

This creates data inconsistency:

• If promotional: "false" (string): derived tables return true, base table returns false
• Components will have mismatched values between base and derived tables

Fix by aligning the logic:

is_extended_promotional: Boolean(
  c.extra && 
  JSON.parse(c.extra).promotional && 
  JSON.parse(c.extra).promotional !== 'false'
)

Or better, cache the parsed value to avoid parsing twice and handle edge cases.

Suggested change

	is_extended_promotional: Boolean(c.extra && JSON.parse(c.extra).promotional),
	is_extended_promotional: (() => { if (!c.extra) return false; try { const parsed = JSON.parse(c.extra); return Boolean(parsed.promotional && parsed.promotional !== 'false'); } catch { return false; } })(),
