Add a synth drum kit and rebuild as a layered, bit-by-bit arrangement

Nothing starts at once now — the track builds: intro (city alone) -> +pads -> +bass -> +kick pulse -> full kit + melody -> stripped interlude (city alone) -> full reprise -> outro (city fades).

• New voices: instr 10 kick (pitch-drop sine + saturation), instr 11 snare/rim (band-passed noise + tones), instr 12 hats (high-passed noise).

• New master bus (instr 100) sums everything through a soft limiter (clip), and reverb (instr 99) now feeds the master too — so the full stack peaks ~0.31 with zero clipped samples instead of risking overload.

• Score rewritten around PAD/BASS/DRUMKICK/DRUMS/MEL macros keyed by start beat; arrangement reads as labelled section calls. ~3 min.

• Renders clean under csound 6.18.
