Rename maglev-frontend → maglevd-frontend; v0.9.1; API RX/TX pulse
Rename the web dashboard binary to maglevd-frontend and move it to /usr/sbin (it's a daemon and belongs with maglevd). The systemd unit name stays vpp-maglev-frontend.service since that prefix is the package name. Manpage, README, user-guide, and debian packaging all updated in lockstep; bump to 0.9.1 for the first real release. All frontend env vars are now prefixed MAGLEV_FRONTEND_ so a single /etc/default/vpp-maglev can be shared with maglevd without collisions. Every flag has an env equivalent for Docker use. MAGLEV_FRONTEND_USER and MAGLEV_FRONTEND_PASSWORD still gate the /admin surface. VPPInfoPanel now pulses "API: ↑↓" indicators in the zippy title whenever a vpp-api-send / vpp-api-recv log event arrives on the SSE stream for the scoped maglevd — 250ms blue flash, re-triggerable, with the two arrows tightly kerned via negative letter-spacing. |

Add WatchEvents, enable/disable/weight RPCs, and config check
gRPC / proto - Rename WatchBackendEvents → WatchEvents; return a stream of Event oneof (LogEvent, BackendEvent, FrontendEvent) with optional filter flags (log, log_level, backend, frontend) - Add EnableBackend, DisableBackend, SetFrontendPoolBackendWeight RPCs - Rename PauseResumeRequest → BackendRequest - Add CheckConfig RPC returning ok/parse_error/semantic_error maglevd - Route slog through a LogBroadcaster (slog.Handler) so WatchEvents subscribers can receive structured log records independently of the daemon's own --log-level - Add --reflection flag (default true) to toggle gRPC server reflection - Add --check flag: validates config file and exits 0/1/2 - SIGHUP: use config.Check before applying reload; log parse vs semantic error separately; refuse reload on any error - Rename default config path /etc/maglev → /etc/vpp-maglev maglevc - Add 'watch events [num <n>] [log [level <level>]] [backend] [frontend]' command; prints compact protojson, stops on any keypress or Ctrl-C; uses cbreak mode (not raw) so output post-processing is preserved - Add 'set backend <name> enable|disable' - Add 'set frontend <name> pool <pool> backend <name> weight <0-100>' - Add 'config check' command Debian packaging - Rename service unit to vpp-maglevd.service - Rename conffiles to /etc/default/vpp-maglev and /etc/vpp-maglev/ - Create maglevd system user/group in postinst; add to vpp group if present - Add postrm; add adduser to Depends |

Pools, CLI, versioning, Debian packaging, HTTPS fix
- Replaced flat `backends: [...]` list on frontends with an ordered `pools:`
list; each pool has a name and a map of backends with per-pool weights (0–100,
default 100). Pools express priority: first pool with a healthy backend wins.
- Removed global backend weight (was on the backend, now lives in the pool).
- Config validation enforces non-empty pools, non-empty pool names, weight
range, and consistent address families across all pools of a frontend.
- Added `PoolBackendInfo { name, weight }` and changed `PoolInfo.backends` from
`repeated string` to `repeated PoolBackendInfo` so weights are visible over
the API.
- Full interactive shell with readline, tab completion, and `?` inline help.
- Command tree parser (Walk) handles fixed keywords and dynamic slot nodes;
prefix matching with exact-match priority.
- Commands: `show version/frontends/frontend/backends/backend/healthchecks/
healthcheck`, `set backend <name> pause|resume`, `quit`/`exit`.
- `show frontend` output is hierarchical (pools → backends) with per-backend
weights and `[disabled]` notation; pool section uses fixed-width formatting
so ANSI color codes don't corrupt tabwriter alignment.
- `-color` flag (default true) wraps static field labels in dark-blue ANSI;
works correctly with tabwriter because all labels carry identical-length
escape sequences.
- `cmd/version.go` package holds `version`, `commit`, `date` vars set at build
time via `-ldflags -X`.
- `make build` / `make build-amd64` / `make build-arm64` all inject
`VERSION=0.1.1`, `COMMIT_HASH` (from `git rev-parse --short HEAD`), and
`DATE` (UTC ISO-8601).
- `maglevc` prints version on interactive startup and exposes `show version`.
- `maglevd` logs version/commit/date at startup; `-version` flag prints and exits.
- `doHTTPProbe` was building a `https://` target URL even though TLS was already
applied to the connection inside `inNetns`. `http.Transport` then wrapped the
connection in a second TLS layer, producing "http: server gave HTTP response
to HTTPS client". Fixed by always using `http://` in the target URL.
- Added `TestHTTPSProbe` using `httptest.NewTLSServer` to cover the full path.
- New `docs/user-guide.md`: maglevd flags/signals, maglevc commands, shell
completion, and command-tree parser walkthrough.
- New `docs/healthchecks.md`: state machine, rise/fall model, probe intervals,
all transition events with log examples.
- Updated `docs/config-guide.md`: pools design, removed global weight from
backends, updated all examples.
- Updated `README.md`: packaging table, build paths, corrected binary locations
(`/usr/sbin/maglevd`), config filename (`.yaml`).
- `debian/` directory contains `control.in`, `maglevd.service`, `default.maglev`,
`maglev.yaml` (example config), `conffiles`, `postinst`, `prerm`.
- `debian/build-deb.sh` stages a package tree and calls `dpkg-deb`; emits
`build/vpp-maglev_<version>~<commit>_<arch>.deb`.
- Cross-compiles for amd64 and arm64 in one `make pkg-deb` invocation.
- `maglevd` installed to `/usr/sbin/`, `maglevc` to `/usr/bin/`.
- Service reads `MAGLEV_CONFIG` from `/etc/default/maglev`
(default: `/etc/maglev/maglev.yaml`).
- Man pages `maglevd(8)` and `maglevc(1)` live in `docs/` and are gzip'd into
the package.
- All build output goes to `build/<arch>/`; `build/` is gitignored.
