Documentation tooling:
- Add the `build-doc` skill and `tools/build_doc.py` wrapper for local
Sphinx builds (clean / -W / open).
- Enable Markdown (MyST) in conf.py and auto-collect
examples/{device,host,dual}/*/README.md into a 3-level Examples nav
(Examples > Device/Host/Dual > example), noting each page's source
location and normalizing headings to a single H1.
- Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md
Documentation section at the skill.
Example docs:
- Add a README.md for every device/host/dual example: what it does, USB
interface table, notable tusb_config.h settings, generic CMake + Make
build steps, and how to try it.
- Fold each *_freertos variant into its base README, noting the FreeRTOS
source path and any RTOS-specific behavior.
Generated docs/examples/ output is git-ignored. Builds clean with
`sphinx-build -W`.

CFG_TUD_MSC_EP_BUFSIZE: 4096 → (HS ? 4096 : 1024). Keep the big buffer for
HS where it actually amortises CBW overhead at iperf-class throughput; FS
peaks around ~830 kBps so 1 KB is plenty and the example now fits on
small-RAM MCUs (lpc11/13, samd11, kinetis_kl, stm32f0/l0, stm32f1, etc.).
Also dedupe CDC_TX_BUFSIZE = CDC_RX_BUFSIZE.
Drops the previously-needed skip.txt — verified builds locally on
lpcxpresso1347, cynthion_d11, lpcxpresso11u37/u68, stm32f072disco/eval,
frdm_kl25z, stm32l052dap52.

The example uses 4 KB MSC bulk buffer + 2-4 KB CDC buffers to push USB
throughput, which overflows on lpcxpresso1347 (RamUsb2) and cynthion_d11.
Skip the same MCU set as net_lwip_webserver — these targets don't have
the RAM headroom to benefit from throughput tuning anyway.
