fix(server): shut down through fx so buffered reports flush (closes #22 )

The server ran os.Exit at the end of its own goroutine, which raced fx's
teardown and could kill the process before reportbuf's OnStop flushed the
buffer — losing up to a full flush window of telemetry on every restart,
silently and with exit 0. The server now requests shutdown through
fx.Shutdowner, so fx runs every OnStop in dependency order.

The http.Server is built synchronously in OnStart before the serving
goroutine starts, so shutdown can no longer race or nil-deref it; the
field is never written and read from two goroutines without a
happens-before edge. A listen failure now exits non-zero via
fx.ExitCode(1). reportbuf's OnStop is guarded by sync.Once. writeTimeout
now exceeds the chi per-request budget, with a comment, so that budget is
reachable. Dead startupTime, exitCode, and cancelFunc fields are gone.

A new test buffers a report and asserts it reaches disk after the fx
lifecycle stops.

Status

pre-1.0. No git tags. Backend work in flight on feat/reportbuf-storage (dirty: src/main.js). Frontend is functional; backend is new and unmerged.

Next Step

Land feat/reportbuf-storage: finish the in-progress src/main.js change, get make check green, and merge the branch to main. The branch adds the backend (buffered zstd-compressed report storage), the CI workflow, and backend repo standard files, so merging it also closes most compliance gaps.

Completed Steps

2026-09-21: shutdown lifecycle correctness. The process now shuts down through fx instead of os.Exit, so every component's OnStop runs and buffered reports are flushed to disk on SIGTERM — previously a full flush window of telemetry was silently lost on every restart. The http.Server is now built before its serving goroutine starts, so shutdown can no longer race or nil-deref it; a listen failure exits non-zero via fx.Shutdowner; reportbuf OnStop is idempotent; and writeTimeout now exceeds the chi per-request budget so that budget is actually reachable. Dead startupTime, exitCode, and cancelFunc fields were removed
2026-08-10: every interactive control now meets the 44x44 CSS px minimum tap target (.pin-btn, #interval-select, the debug-log label and, on narrow viewports, #pause-btn). The pin button's hit area grows via matching negative margins, so its layout footprint and row density are unchanged
2026-08-10: per-host status line wraps below the 768px breakpoint instead of forcing horizontal page scroll at 320px
2026-08-09: Dockerfile.backend reworked to the mandated Go multistage lint-stage pattern: separate lint stage on the hash-pinned golangci/golangci-lint image, COPY --from=lint stage dependency, CGO_ENABLED=0 static build driven by ARG VERSION, and no more COPY .git
2026-08-09: dotfile compliance — lifted backend/.editorconfig to the repo root so root = true covers the frontend too, and replaced .gitignore with the org model (OS, editor, node, and environment/secrets sections) plus this repo's dist/ and *.log. .env, .env.*, *.pem, and *.key are now ignored repo-wide, not just under backend/. Excluding .git from .dockerignore stays deferred: both images read git metadata at build time (COPY .git in Dockerfile.backend, git rev-parse in vite.config.js)
2026-07-07 Adopted scripts-to-rule-them-all: script/ entrypoints, Makefile shims, README Entrypoints section
2026-02-27: backend with buffered zstd-compressed report storage; CI workflow and backend repo standard files; backend Dockerfile fixed (Go 1.25, golangci-lint) and moved to repo root (feat/reportbuf-storage, unmerged)
2026-02-26: host row layout redesigned with CSS grid; overflow and spacing fixes; nginx config extracted; port hardcoded to 8080
2026-02-26: debug log panel, median stats, recovery probe, Docker build fix, S3 Singapore endpoint added
2026-02-23: summary box redesign, host pinning, local and UTC clocks, checks counter
2026-02-23: hosts sorted by latency; GET instead of HEAD for latency; timeout derived from interval; Hetzner regional endpoints; 3s interval
2026-01-29: initial NetWatch network latency monitor

Future Steps

Compliance top-up as one small commit: add .editorconfig and add the hooks target to the Makefile
After merge, confirm .gitea/workflows/check.yml is on main and CI is green (main always green policy)
Decide what to do with untracked resume.sh: commit it, gitignore it, or delete it
