Update DB timestamp; add ti99sim emulator

Bump database.json generated_at timestamp and add a new emulator metadata file emulators/ti99sim.yml. The new YAML registers the TI-99/Sim standalone emulator (ti99sim) with system info, core version, notes on ROM handling, and multiple required/optional ROM entries (with SHA1s, sizes and validation notes) for TI-99/4A support.

+  Marc Rousseau's TI-99/4A simulator (since 1993). Standalone only, no libretro port.
+  Uses proprietary .ctg cartridge format for ROM packaging (CPU ROM + GROMs + RAM config).
+  Raw ROM dumps must be converted to .ctg via the convert-ctg utility.
+  File search order: CWD, CWD/console/ (v0.16.0) or CWD/roms/ (<=0.0.11),
+  ~/.ti99sim/console/, /opt/ti99sim/console/.
+  v0.16.0 adds SHA1-based auto-discovery for device ROMs in the console/ directory.
+  Recalbox packages ti99sim as a standalone emulator for the ti994a system.
