torlando-techandClaude Opus 4.7 5a3ee97856 deps(codec2): vendor codec2 v1.2.0, replace sh123/esp32_codec2_arduino@1.0.7 
The PlatformIO dep sh123/esp32_codec2_arduino@1.0.7 bundles codec2
v0.9.2. Mac-side pycodec2 v3.0.4 links libcodec2 v1.2.0. Years of
codec2 development between those releases.

Replace the upstream lib with a local vendor of drowe67/codec2 v1.2.0
under lib/codec2/. Trim the 191-file source tree down to the
~100 files actually needed for codec2 (drop FreeDV, OFDM, COHPSK,
FSK, FM-FSK, LDPC, Horus, CLI tools — pyxis only uses
codec2_create/destroy/encode/decode + samples_per_frame /
bytes_per_frame). Carry over the v0.9 codebook .c files since the
codebook contents matched (compared against v1.2's src/codebook/*.txt).

Define __EMBEDDED__ so the codebooks land in flash (.const) rather
than RAM. Without it the codebooks add ~127KB to BSS and the LVGL
task fails to start (RAM was 65% full vs 27% with __EMBEDDED__).
Provide trivial codec2_malloc/codec2_free wrappers in
codec2_alloc_esp32.c (codec2 v1.2 expects them when __EMBEDDED__ is
defined; ESP-IDF's malloc/free already pull from internal RAM).

Also explicitly add SD/FS to lib_deps and #include <SD.h> in
main.cpp — the previous esp32_codec2 dep transitively pulled SD
which let SDArchiveFileSystem.h get away with depending on it
implicitly. With chain+ ldf mode and no esp32_codec2 dep, we have
to declare the framework lib explicitly.

DOES NOT fix the ~30x speech-decode RMS asymmetry between pycodec2
self-tests (~5800) and pyxis decoding the same encoded bytes (~170).
Sine waves and 3-formant synthesis pass clean both directions; only
real TTS speech triggers it. Probably a separate codec-state
divergence (the encoder/decoder are independent codec2 instances
in pyxis, both fresh per call) or a wire-format quirk we still need
to track down. v1.2 is the right baseline regardless — same bug
class as several upstream fixes.
