Add all ti-sysblocks chip recommendations

[seveibar]

Summary

• add all 810 unique TI product families referenced by tscircuit/ti-sysblocks
• expose 800 exact orderable-MPN components and reuse 10 existing family definitions
• keep raw chip modules as plain lib/chips/*.tsx; reserve *.circuit.tsx for runnable examples, subcircuits, and simulations
• retain component footprints while removing the footprint-selection, footprint-catalog, and materialization JSON artifacts
• add package-aware pin maps and a schematic-layout helper that preserves tscircuit's 0.2 mm adjacent-pin spacing
• add 21 reusable, named TI-reference blocks with matching schematic-only snapshots
• let tscircuit autoroute every example schematic: no manual schematic geometry, <schematictext>, custom drawing symbols, or schematicRouteHints
• disable SPICE solving in CI through platformConfig.spiceEngineMap; local simulation engines remain enabled
• add a CI workflow that validates reference evidence and checks schematic-only snapshots

The sysblocks diagrams use generic TI product-page names rather than exact package variants. Each of the 800 generated families therefore selects one active orderable MPN/package in lib/chips/ti-sysblocks-chip-catalog.json; the exact MPN export remains available when the package choice must be explicit.

Reusable TI reference blocks

The example library intentionally samples useful public TI reference circuits instead of inventing a circuit for every chip. Each block named-exports a reusable component, default-exports the same component as a runnable example, records its first-party TI figure/page in examples/ti-reference-examples.json, and has one reviewed schematic snapshot.

Examples use ordinary <trace> elements only to declare electrical connectivity; tscircuit chooses the schematic paths. Repository validation rejects manual schematic geometry, <schematictext>, custom drawing symbols, and schematicRouteHints in every runnable example. An example is omitted when automatic layout cannot reproduce the cited TI figure readably.

• Power and drivers: BQ25185_TypicalBatteryCharger, DRV8833_ParallelMotorDriver, TLV755P_TypicalApplication, TPS22919_LoadSwitchTypicalApplication, TPS61165_WhiteLedDriver, TPS61299_5VBoostConverter, TPS62A01_1V8BuckConverter, TPS7A20_TypicalApplication, TPS92612_LinearLedDriver
• Analog, sensing, and conversion: ADS7042_DirectSensorInterface, INA138_BasicCurrentSense, LM358B_InvertingAmplifier, LMT70_AnalogTemperatureToAdc, OPA320_SecondOrderLowPassFilter, OPA371D_LowSideCurrentSense
• Logic, interface, clocking, wireless, and timing: CC2340R5MODA_TypicalApplication, LMC555_MonostableLedFlasher, LMK1C1104_ClockFanout, SN74AHC1G14_SwitchDebouncer, SN74AUP1G17_TurnOnPulseGenerator, TCAN1044A_5VCanInterface

The generated examples/index.ts exports all blocks and the typed TiReferenceBlockComponents map. Families without a sufficiently clear public TI schematic are deliberately skipped.

Validation

• bun run validate:ti-sysblocks — 810 families: 689 JLCPCB, 111 TI-datasheet, 10 existing
• bun run validate:ti-reference-examples — 21 evidence-backed blocks, including 20 sysblocks families
• bun scripts/validate-ti-reference-examples.ts --verify-evidence — all 21 first-party TI evidence URLs resolve
• bun test scripts — 47 passing
• bun run typecheck
• bun run format:check
• CI=true bun run snapshot:schematics — all 22 runnable example schematics match their snapshots
• git diff --check

The hosted tscircuit/build result is not treated as a gate for this PR because the package is too large for that builder, per maintainer direction.
