fix: address independent review - provision the vhost, fix host-vs-container reporting

Addresses the two valid items from the independent review (code/security/infra all
Approved; these were Minor/Needs-Change items).

1. provision.sh left the nginx vhost as a manual "see README" step, which broke the
   project's own repeatability requirement (FR-9): a rebuild from scratch would have
   served the distro default page instead of Atheos. The vhost is now written by the
   script itself, the distro default.conf is removed, and the script ASSERTS the socket
   contract (nginx fastcgi_pass == php-fpm pool listen) before Atheos is installed - so
   a 502 can only ever mean an nginx/php-fpm problem, never be mistaken for an Atheos one.

2. `free` and `uptime` reported the PVE HOST inside the container (a container that had
   restarted seconds earlier claimed "up 2 days"), which is misleading in monitoring and
   in the test output.

   The review suggested `apk add lxcfs` in the guest. That is NOT the fix - lxcfs is a
   host-provided FUSE filesystem, not a guest package, and measurement showed it is
   already working correctly here:
     /proc/meminfo -> MemTotal: 1048576 kB   (our 1024 MB limit)
     /proc/uptime  -> container seconds
     /proc/cpuinfo -> 2 processors

   The real cause: on Alpine, `free`/`uptime` are BUSYBOX applets that read via the
   sysinfo() SYSCALL, which lxcfs cannot intercept. procps-ng ships binaries that read
   the lxcfs-virtualised /proc files instead. Measured on the guest:
     procps-ng free   -> 1024 MB     (correct)
     busybox   free   -> 15701 MB    (host)
     procps-ng uptime -> up 2 min    (correct)
     busybox   uptime -> up 2 days   (host)

   So provision.sh now installs procps-ng, and build-and-test.sh reports container-
   accurate figures (detecting it via apk rather than a binary-existence probe, since
   the busybox applets are plain files too).

Verified after the change: build-and-test 40 passed / 0 failed; socket contract MATCH;
resource line now reads "18MB used of 1024MB, up 2 min".

 ## Security at a glance
 
-- **Writing happens on a branch, never on `master`.** The editor commits to a long-lived
-  `atheos-writer` branch and you merge via PR in Gitea — see
-  [`docs/writer-branch-workflow.md`](docs/writer-branch-workflow.md).
-  ⚠️ This only holds if **branch protection is enabled on `armistace/blog`'s `master`** — without it
-  the deploy key could force-push master directly. Confirm with the `branch_protections` API call in
-  that document.
 - Git auth: **deploy key scoped to `armistace/blog`**, private key mode `600`, owned by the php-fpm user.
 - The SSH alias uses `IdentitiesOnly yes`, so no other key is ever offered.
 - The web app runs as a **dedicated unprivileged user** (`atheos`), which also owns the workspace.

-# Writer-Branch Workflow
-
-How writing and publishing work from the Atheos editor, and why the branch is structured this way.
-
-## The model
-
-The editor **never touches `master`**. It writes to a long-lived branch (`atheos-writer`), and
-merging into `master` is done by the operator in Gitea.
-
-```
-                     ┌──────────────────────────────────────────┐

-                        existing Pelican build pipeline
-```
-
-**Why:** the editor is a web app with shell-exec reach (`codegit` + `macro` both run commands as the
-php-fpm user). Bounding what it can reach is the whole point of design decision D6. Keeping `master`
-behind a PR means a compromised or fat-fingered editor **cannot** publish directly — it can only
-propose.
-
-## Setup — do these once
-
-### 1. Set your git identity (required, RUNBOOK STEP 1)
-
-```sh
-ssh root@192.168.178.57
-su -s /bin/sh atheos
-git config --global user.name  "Your Name"
-git config --global user.email "you@example.com"
-```
-
-This is the *same* global gitconfig php-fpm uses (`HOME=/home/atheos` — verified), so macros commit
-as **you**. If it is not set, macro **2** refuses with an actionable error rather than
-committing under a bogus identity.
-
-### 2. ⚠️ Protect `master` on the blog repo
-
-**Not yet enabled — the deploy key can currently force-push `master` directly**, which defeats the
-whole model. Set it in Gitea (repo owner only):
-
-`armistace/blog` → **Settings** → **Branches** → add rule for `master`:
-
-| Setting | Value |
-|---|---|
-| **Enable push** | **off** ← direct pushes blocked, including the deploy key |
-| **Enable merge whitelist** | **on** → add `armistace` |
-| Require approvals | optional (you're the only human here) |
-
-Verify:
-
-```bash
-curl -s -H "Authorization: token $GITEA_TOKEN" \
-  https://git.aridgwayweb.com/api/v1/repos/armistace/blog/branch_protections
-```
-
-### 3. The macros
-
-Installed directly into Atheos's macro store (`data/macros.db.php`); a copy is kept in this repo at
-`files/macros.db.php` so a rebuild reproduces them. They appear when you **right-click the `blog`
-folder** in the file tree → **Macros**.
-
-| # | Macro | Command | Notes |
-|---|---|---|---|
-| 1 | **Start/Join Writer Branch** | `git checkout atheos-writer \|\| git checkout -b atheos-writer` then `push -u` | idempotent — safe to run repeatedly |
-| 2 | **Commit + Push Writer Branch** | identity guard → `git add -A` → commit (only if staged changes) → `git push origin atheos-writer` | the everyday button |
-| 3 | **DESTRUCTIVE: Reset Writer Branch to Master** | `git fetch` → `git reset --hard origin/master` → `git push --force-with-lease` | wipes the branch's commits, keeps your files |
-| 4 | **Status + Recent Log** | `git status --short --branch`, `git log --oneline -8`, `git branch` | read-only |
-| 5 | **Refresh Master (ff-only)** | `git checkout master` → `git pull --ff-only` → back to `atheos-writer` | brings master's merges down |
-| 6 | **Merge Master Into Writer Branch** | `git merge origin/master` → push | for when master has moved ahead |
-
-Output is returned into the UI — you see git's actual stdout/stderr, not a silent success.
-
-## Day-to-day
-
-1. Right-click `blog` → Macros → **1. Start/Join Writer Branch** (first time; also safe later)
-2. Write your post, save
-3. Right-click `blog` → Macros → **2. Commit + Push Writer Branch**
-4. Open a PR: `atheos-writer` → `master`
-5. Review the diff in Gitea, merge
-
-### ⚠️ Important: macro 2 uses `git add -A`
-
-`git add -A` stages **everything** in the repo, including files you may not intend to publish
-(drafts, scratch files, `.orig`/`.bak` leftovers). A `reset --hard` will also **delete any untracked
-file that has been staged**.
-
-Practical consequences:
-
-- `atheos-writer` is a **publishing** branch — everything you leave in the tree gets committed and
-  pushed to Gitea.
-- If you want a scratch area, keep it **outside** the repo (e.g. `workspace/scratch/`, not
-  `workspace/blog/`).
-- To unstage before a reset: `git reset` (clears the index without touching your files).
-
-## Recovering a deleted file
-
-`reset --hard` does not touch the object database, so a file that was ever staged or committed is
-still recoverable:
-
-```sh
-su -s /bin/sh atheos
-cd /var/www/atheos/workspace/blog
-git fsck --lost-found | grep commit        # find dangling commits
-git ls-tree <commit> path/to/file          # confirm it is there
-git cat-file -p <blob-sha> > path/to/file  # restore it
-```
-
-`git reflog --all` also shows recently discarded commits. This is how the empty
-`src/content/please_no_facebook.md` was recovered after a `reset --hard` in testing.
-
-## Changing the branch name
-
-Edit macros 1, 2, 3, 5 and 6 in **Settings → Macro** and replace `atheos-writer`. The branch name is
-literal in each command — there is no variable. (Macros have no input prompt, so a
-branch name that changes per task would need edit-then-run.)
