- lib/common.sh: add apt_lock_wait + apt_install + apt_update helpers
* waits up to 300s for dpkg lock held by unattended-upgrades
* uses DPkg::Lock::Timeout=120 native flag
* captures stderr to show real error if install fails
- lib/website.sh: install_nginx/install_certbot use apt_install
(fixes "Could not get lock /var/lib/dpkg/lock-frontend" during Pro setup)
- install.sh: bot_install uses apt_install (removes duplicated lock logic)
- lib/common.sh: ensure_deps uses apt_update + apt_install
- bot_install: wait up to 300s for dpkg/apt lock (unattended-upgrades)
- use apt-get -o DPkg::Lock::Timeout=120 as extra safety
- detect python3 minor version and include python3.X-venv in package list
- stop silencing apt errors with 2>/dev/null — surface them to user
- python3-full is optional; fall back to core packages if unavailable
- venv fallback path also installs versioned package and retries
- templates_catalog.json: skip cp when source==dest (symlink install)
Iteration 3 discovered a race condition: parallel CLI invocations of
change-lite-domain occasionally produced 'no secret in config' because
one process read config.json while another was mid-rewrite (jq -> tmp -> mv).
asyncio.Lock in bot.py only protects bot->bot races; CLI-level races and
bot+CLI mixed races were still possible.
- install.sh: bot_action_dispatch wraps dispatch in flock(1) on
/var/lock/gotelegram-bot-action.lock, 30s timeout, EX_TEMPFAIL on timeout
- common.sh: flock added to critical deps; apt_pkg_for_cmd/dnf_pkg_for_cmd
map flock -> util-linux
- common.sh: check_deps_present includes flock
- version bumped to 2.4.3 (common.sh + bot.py)
- install.sh: new bot_action_dispatch entry point for --action=X --json CLI invocation from the bot/scripts
- install.sh: bot_action_change_template — reuses download_template + deploy_template_to_nginx, updates config.json template_id
- install.sh: bot_action_change_lite_domain — regenerates telemt TOML with new fake-TLS mask domain, restarts telemt
- bot.py: run_bot_action() subprocess wrapper parses JSON result
- bot.py: cb_pro_confirm now performs real change-template when already in pro mode (fresh install still routes to CLI)
- bot.py: cb_lite_domain now performs real change-lite-domain when already in lite mode
- version -> 2.4.2
- install.sh: fix {{NC}} -> ${NC} color escape on line 265
- bot.py: fix TOML parsing for telemt v3 [access.users] format
- bot.py: fix telemt config section [server].port instead of [config].listen_port
- telemt_config.sh: fix add_secret_to_config() for v3 format
- All frame boxes: correct 54-char width with emoji compensation
- Lite mode links now include ee-prefix + mask_host hex (fake-TLS)
- Added qrencode to ensure_deps() so QR codes work after fresh install
- Centralized link generation in generate_proxy_link()
- Fixed bot.py get_proxy_link() for lite mode ee-prefix
