* core: add progress; fix exit status
Introduce post_progress_to_api() in alpine-install.func and install.func to send a lightweight, fire-and-forget telemetry ping (HTTP POST) that updates an existing telemetry record to "configuring" when DIAGNOSTICS=yes and RANDOM_UUID is set. The function is non-blocking (curl -m 5, errors ignored) and is invoked during container setup and after OS updates to signal active progress. Also adjust api_exit_script() in build.func to report success (post_update_to_api "done" "0") for cases where the script exited normally but a completion status wasn't posted, instead of reporting failure.
* Safer tools.func load and improved error handling
Replace process-substitution sourcing of tools.func with an explicit curl -> variable -> source via /dev/stdin, adding failure messages and a check that expected functions (e.g. fetch_and_deploy_gh_release) are present (misc/alpine-install.func, misc/install.func). Add categorize_error mapping for exit code 10 -> "config" (misc/api.func). Tweak build.func: minor pipeline formatting and change the ERR trap to capture the actual exit code and only call ensure_log_on_host/post_update on non-zero exits, preventing erroneous failure reporting.
* tools: add data init and auto-reporting to tools and pve section
Introduce telemetry helpers in misc/api.func: _telemetry_report_exit (reports success/failure via post_tool_to_api/post_addon_to_api) and init_tool_telemetry (reads DIAGNOSTICS, starts install timer and installs an EXIT trap to auto-report). Integrate telemetry into many tools/addon and tools/pve scripts by sourcing the remote api.func and calling init_tool_telemetry (guarded with declare -f). Also apply a minor arithmetic formatting tweak in misc/build.func for RECOVERY_ATTEMPT.
* FileBrowser Quantum: safer update (tmp download + atomic replace + arch autodetect)
**What**
Safer updater for FileBrowser Quantum addon:
- Download to temp file, then atomic `mv` into INSTALL_PATH
- Stop/start service around the swap
- CPU arch autodetect (amd64/arm64/armv7/armv6)
- Proper error handling & version verification before printing success
**Why**
Current update streams `curl` directly to `/usr/local/bin/filebrowser` and prints success even if `curl` fails.
I hit:
* fix(filebrowser-quantum): add missing `fi` before install section
Closes the conditional started with `if [[ -f "$INSTALL_PATH" ]]` so the script doesn’t hit a bash syntax error when reaching the install path.
* refactor(update): minimal fix - temp file + atomic mv; amd64 only
* style(update): remove comments/blank lines; drop restart (alpine-safe)
