fix(server): resolve clone/upload/mapping roots from GITNEXUS_HOME (#2229)
* fix(server): resolve clone/upload/mapping roots from GITNEXUS_HOME

CLONE_ROOT (git-clone.ts), UPLOAD_ROOT (upload-paths.ts), and the
server-mapping file (embeddings/server-mapping.ts) computed their root
from os.homedir() directly, ignoring GITNEXUS_HOME. The Docker image
sets GITNEXUS_HOME=/data/gitnexus (the persistent volume that also holds
the registry and indexes), so cloned/uploaded repos and their .gitnexus
indexes instead landed in the container's ephemeral ~/.gitnexus and were
lost on container recreation, while registry.json (which honors
GITNEXUS_HOME) kept pointing at the now-dead path. That also defeated
incremental re-analysis: a recreated container re-clones from scratch and
full-rebuilds instead of git pull + incremental update.

Source all three from the existing getGlobalDir() helper — the same
GITNEXUS_HOME-aware primitive the registry and groups already use.
Behavior is unchanged when GITNEXUS_HOME is unset (CLI / local installs):
it falls back to ~/.gitnexus exactly as before. No signatures change and
no UPLOAD_ROOT consumers are touched.

Adds test/unit/gitnexus-home-roots.test.ts covering both the
GITNEXUS_HOME-set and unset paths for all three roots.

* test(server): make clone-root assertions GITNEXUS_HOME-aware; cover server-mapping fallback

Addresses PR review (#2229):

- git-clone.test.ts hardcoded path.join(os.homedir(), '.gitnexus', 'repos')
  for the clone root, so the "direct child of the clone root" and containment
  assertions failed when GITNEXUS_HOME was set in the ambient env (e.g. a CI
  runner). CLONE_ROOT now derives from getGlobalDir(); mirror that derivation
  via EXPECTED_CLONE_ROOT (GITNEXUS_HOME || ~/.gitnexus), computed at module
  load — the same point CLONE_ROOT is frozen — so the two always agree.

- The GITNEXUS_HOME-unset fallback test covered clone + upload roots but not
  server-mapping (one of the three changed modules). Add a fallback case for
  readServerMapping. It redirects HOME/USERPROFILE to a tmp dir (os.homedir()
  honors them) so it exercises the real ~/.gitnexus fallback without writing
  into the developer's actual ~/.gitnexus/server-mapping.json.

Both files pass with and without GITNEXUS_HOME set.

* test(server): use mkdtemp for GITNEXUS_HOME path-root test temp dirs

CodeQL js/insecure-temporary-file flagged the two writes that used a fixed
os.tmpdir() name (gitnexus-home-roots-test, gitnexus-fallback-home): a
co-located process could pre-create or symlink the predictable path before
the test write lands. Switch both to fs.mkdtemp(), which atomically creates a
uniquely-named directory — the canonical sanitizer this repo already uses
(see core/group/storage.ts). Behavior is unchanged; tests still pass with and
without GITNEXUS_HOME set.

* fix(embeddings): resolve server-mapping path for parity with clone/upload roots

MAPPING_FILE now wraps path.resolve() like CLONE_ROOT (git-clone.ts) and
UPLOAD_ROOT (upload-paths.ts), so a relative GITNEXUS_HOME yields an absolute
path. No-op for the supported absolute-GITNEXUS_HOME config (Docker) and for
readServerMapping's only caller (run-analyze.ts).

* test(server): derive EXPECTED_CLONE_ROOT from getGlobalDir() to avoid drift

The test mirror now imports getGlobalDir() and computes the expected clone root
the same way production CLONE_ROOT does, instead of re-deriving the
GITNEXUS_HOME || ~/.gitnexus fallback by hand. Byte-identical today; future-proof
if getGlobalDir() grows a branch. (os import retained — still used by os.tmpdir().)

* test(server): rename shadowed savedHome in server-mapping fallback test

The inner savedHome (saves process.env.HOME) shadowed the describe-scope
savedHome (saves process.env.GITNEXUS_HOME). Renamed the inner one to
savedProcessHome at its declaration and both restore sites in the finally
block. Pure rename, no behavior change.

* test(server): scope customHome temp dir to the GITNEXUS_HOME-set cases

beforeEach created a customHome temp dir for all five tests, but the two
fallback cases never use it (one manages its own fakeHome, the other needs
none). Moved the mkdtemp/rm into a nested describe('with GITNEXUS_HOME set')
wrapping the three set-cases; the shared outer afterEach still restores
GITNEXUS_HOME and resets modules for all five.
