Rongsong Shen e4fd9e1d3f feat(admin-config-tool): wire xceadmin into meson + nix build
Reopens the 2026-07-21 design decision to keep xceadmin outside meson.
Standard onboarding consistency (README 3.3 `nix build .#xcecore` and
3.4 `meson compile` working for xceadmin like every other component)
outweighs the earlier concern about meson's single-artifact model not
fitting a multi-file pip install.

- src/xceadmin/meson.build: custom_target() wrapping install+test,
  stamp-file output, build_always_stale (matches this repo's existing
  clean-rebuild-every-invocation convention).
- src/xceadmin/meson-build.sh: out-of-tree pinned install + pytest;
  stages a repo-mirror/ symlink tree so tests' fixed-relative-path
  assumptions (src/configs/, src/schema/, ha/data/) still resolve from
  a copied location, without touching their deliberate fail-loud
  behavior.
- src/meson.build: subdir('xceadmin') under component != 'xcecli'.
- src/tools/xce-build.sh: xceadmin case now delegates to
  `meson compile -C "$BUILD_DIR" xceadmin` instead of its own
  pip/venv implementation, like every other component.

Verified both build paths: meson compile (165/165 passed) and
nix build --option sandbox false .#xcecore_debug (128 passed / 37
skipped — cert-dependent tests correctly skip under nix's
git-tracked-only hermetic source). AppImage bundling (README 3.5)
is explicitly deferred to future work, not part of this change.

# Meson-driven xceadmin build: install + test out-of-tree, in the meson
# build directory. Never writes into the live source checkout -- unlike
# xce-build.sh's separate xceadmin case (editable install, .venv inside
# src/xceadmin/, meant for fast dev-loop iteration), this path is what
# `meson compile`/`nix build .#xcecore` actually invoke, and both need
# the same purity guarantee every other meson subdir here already has.
#
# Several tests reach for sibling directories outside xcecommon/xceadmin's
# own tree via a fixed relative path (src/configs/, src/schema/, ha/data/
# -- e.g. test_validation.py's REPO_CONFIGS_DIR deliberately fails loud
# rather than skips if that layout assumption breaks, by design). Rather
# than touch test code, this script recreates the exact repo layout
# out-of-tree via symlinks (read-only references, never a write into the
# real tree) so every one of those relative-path assumptions still
# resolves correctly from the copied location.
