* Add German translation and harden paths against unset env vars
Add a German locale to the GUI, tray menu, usage alerts and website home page, and refuse to start when the home folder is unset or relative so nothing is written under the working folder; the pi plugin no longer adopts the user's PI_CODING_AGENT_DIR, and an inherited APPIMAGE no longer selects portable mode. Scripts refuse to run from the wrong folder or empty a shared out folder, and a new internal/testenv sandboxes every test package from the user's real files, which also fixes the Claude picker and Termux installer tests on Windows.
* Makefile: know magpie's folder by its go.mod, so paths with spaces work
The check compared $(CURDIR) with $(dir $(abspath …)), which make splits on spaces, so a checkout under 'My Projects' or 'John Doe' refused every target. It now reads go.mod relative to the working folder and wants magpie's module there: make -C and a symlinked Makefile work, make -f from another folder still stops before any recipe runs.
* i18n: German for the strings main added since, with a parity test
75 strings main added (group order, patterns, slow-start wait, usage caps, RTK savings …) get their German, and two that main dropped go. gui-de.test.cjs checks, as gui-ja does, that de has every zh string with its placeholders and tags, and that the window reads in German when picked or on a German system.
* appdir: ignore relative folder variables when reading, keep them for children
CheckEnv no longer unsets anything. magpie reads the XDG folders, APPDATA/LOCALAPPDATA and every agent's folder variable through appdir.Getenv/LookupEnv, which pass over a relative value; the environment stays as it is, so the agents magpie starts get the variable as the user set it. That covers what proc.UserPath lends from the login shell too, which is set after main's check and reached the desktop app unchecked. On Windows a path rooted on the current drive (\Users\x, Git Bash's /c/x) counts as usable, and magpie version and help answer without a home, before run makes any folder.
* Sandbox the tests main added since
internal/wslrun gets testenv's TestMain, and four tests main added that set HOME alone set their home with testenv.SetHome, so on Windows they don't read the runner's profile through USERPROFILE.
* agentenv: PI_CONFIG_DIR and OPENCODE_DB take relative names on purpose
omp puts $PI_CONFIG_DIR under the home and OpenCode a relative $OPENCODE_DB in its data folder, so neither depends on the working folder: appdir no longer passes them over.
* i18n: German for the Library's multi-select and System One's decision API
The 19 strings main added since (#791's skill multi-select, the decision API snippets) get their German; the one main replaced (four APIs → five APIs) goes.
* appdir: tidy the import into magpie's group; say what Go makes of /c/x
The appdir import joins the group of magpie's own imports where a file has one. rooted's comment now says that Go takes a Git Bash path like /c/x as \c\x on the current drive, not C:\x.
* feat(gui): show and filter usage for each API key
* feat(gateway): issue per-user caller keys and attribute usage
* feat(gui): manage gateway users and filter caller-key usage
* test: verify caller-key failover and document user management
* refactor(gateway): use named caller keys without user accounts
* feat(gui): manage named caller keys with existing account styles
* fix: remove user breakdown from CLI and leftover gateway styling
* fix(usage): drop stale user field from request response
* feat(gateway): authenticate LAN calls with named caller keys
* fix(gateway): preserve LAN key rotation in the named caller store
* fix(gui): retain native LAN key copy and rotation controls
* fix(gui): inherit the global theme for API key inputs
* fix(usage): show client API keys using the existing terminology
* fix(gateway): rotate named keys without changing usage identity
* fix(gui): unify gateway keys and selectable connection examples
Keep sharing controls in Settings and manage credentials only in Gateway. Refresh the named-key list on navigation, ignore stale reads after key actions, and generate all API examples from the selected address and enabled key.
* fix(gui): keep caller key names literal in connection menus
* fix(access): use Magpie as default key and drop user migration
* refactor(gui): name caller key source and tests consistently
* refactor(usage): split provider-key accounting out of caller-key PR
* fix(gateway): preserve LAN compatibility and add headless key management
* fix(gui): clarify gateway keys and confirm destructive actions
* test(gateway): guard caller attribution under 120 concurrent requests
* fix(gateway): keep open access, tolerate migration errors and revoke legacy keys
* fix(backup): preserve named gateway keys and honor no-keys restores
* fix(gui): keep local API-key semantics and disambiguate shared credentials
* docs(gateway): keep review scope focused and append browser test documentation
* fix(backup): retain existing default keys when old backups lack their store
* fix(gateway): attribute video creation usage to the caller key
* fix(access): explain default key revocation blocked by read-only settings
* test(usage): preserve provider and caller identities after rebase
* test(gui): reconcile caller key fixtures with merged main
* docs(usage): clarify caller coverage and independent provider accounting
* fix(gui): initialize fast members for model-shortcut groups
Latest main introduced fast-member arrays but omitted the model shortcut's draft. The existing unlisted-models browser regression fails unchanged on main. Initialize fast to an empty list and assert a standard-speed group is saved, without relaxing existing assertions.
* fix(access): retain legacy LAN access when the key store cannot be created
Allow only the configured legacy credential before either migration marker exists. Refuse revoked mirrors, disabled matches and unreadable stores; keep the fallback's caller identity stable when migration later succeeds. Cover read-only configuration directories, remote credential transports and revocation.
* fix(backup): save settings before replacing gateway credentials
Leave the key store untouched when settings validation or writes fail. Restore the previous settings association when the key store refuses its write, and report a rollback failure separately. Cover invalid settings and read-only settings/store failures.
* fix(gui): reset missing caller filters and focus key controls without scrolling
* test(provider): synchronize Zhipu quota fixture observations
