Aaron D. Lee bcd775747a feat(trunk): G711Codec — µ-law encode/decode + 8kHz↔24kHz linear-interpolated resampling (slice-5 T1) ...

In-core ~30-line table-driven codec (no dep). The ITU-T G.711 µ-law
companding formula is a piece of telephony history worth teaching (AGENTS.md
learner-facing comment mandate). 3× linear upsample on decode; 3× decimation
downsample on encode. The resampler artifacts are below the barge-in trigger
threshold (LocalVadReflex only needs RMS energy); rubato lands in a post-
spearhead refinement if a downstream consumer needs better (spec §6.6).

Task T1 of slice-5 — T3 (TwilioMediaStreamsServer) consumes this codec.
