The examples split: component-repo demos, showcase aggregator, shared-helpers package (post-program)

[bdbarnett]

Direction adopted in principle 2026-08-29, deliberately parked until after the modernization program (now complete). Recorded here so it stays visible.

Agreed shape:

• Single-package demos move into their component repos, inheriting per-repo doc-example CI guards.
• Integration showcases + the gallery/PyScript harness stay here — pydevices-examples becomes the showcase/aggregator, and its deploy gains an aggregation step pulling component examples in.
• The shared helpers (tft_config, console, wifi.py, lv_encoder_emu, plus whatever of pydevices' own utils merges in — inventory needed) become their own repo/package, installable whole via mip/pip and per-file via documented raw URLs (mip github single-file paths); each helper must import standalone, CI-checked.

Open decisions for Brad at kickoff:

1. Repo/package name — unprefixed utils is too generic an import; pdutils was floated.
2. The pydevices/utils merge inventory.
