linker: shrink default palette load from inline stores to loop 
The reset-time "no user palette" path was emitting 32 unrolled
`LDA #imm / STA $2007` pairs (~170 bytes) to write the built-in
palette. Replace it with the same indirect-loop loader the
user-palette path already uses (runtime::gen_initial_palette_load),
with the 32-byte default palette spliced into PRG under a
`__default_palette` data block. Net saving is ~120 bytes — ~20
bytes of code + 32 bytes of data vs ~170 bytes of unrolled stores.

Delete `Linker::gen_palette_load` (dead after the refactor) and its
unit test. Replace with two tests covering the observable
behaviour: the default palette bytes appear in PRG when no user
palette is declared, and the `__default_palette` label is
suppressed when the user does declare a palette.

Audio goldens flip again for audio_demo, noise_triangle_sfx, and
sfx_pitch_envelope. These are the three audio examples that don't
declare their own palette — shrinking the default-palette load
shifts their audio tick's absolute address by ~120 bytes, which
changes branch page-crossing timing and therefore the exact APU
register write sample offsets. Same class of drift as the
mul/divide gating commit.
