tests: run the *.test scripts under set -euo pipefail

The test scripts mostly ran with no error flags, so a failing command in
the middle would be ignored and the script would limp on to a misleading
result. Turn on strict mode everywhere, guarding the spots that legitimately
expect a non-zero exit:

- the htssafe overflow probes (-#8) deliberately abort, and the strsafe/
  cmdline crawls capture an exit code to assert on, so those are run with
  `|| true` / `|| rc=$?` rather than letting set -e kill the script first;
- the parser fixture crawl ignores httrack's own exit (it checks the mirrored
  files), so it keeps `|| true`;
- 02_update-cache replaced `find ... | grep -q .` with a `-print -quit`
  command substitution: under pipefail grep -q can close the pipe early and
  leave find killed by SIGPIPE, which would spuriously fail an existing file;
- 12_crawl_https guards $HTTPS_SUPPORT with `${...:-}` for set -u.

02_manpage-regen and 01_engine-cache stay on `set -eu` (no pipefail): both are
run via $(BASH), which can be a plain POSIX /bin/sh where `set -o pipefail`
does not exist.

shellcheck clean; make check: 15 PASS, 7 SKIP (offline).

+# AGENTS.md — working in the HTTrack tree
+
+Policy and PR etiquette live in [CONTRIBUTING.md](CONTRIBUTING.md). This file is
+the operational checklist: toolchain, invariants, and how to ship a change.
+
+## Build & test
+- Fresh clone first: `git submodule update --init src/coucal`
+- `./bootstrap` (regenerates `configure` via `autoreconf`; needs autoconf,
+  automake, libtool), then `bash configure && make && make check`. Or run
+  `sh build.sh` to do bootstrap + configure + make in one shot.
+
+## Hard invariants
+- **Generated autotools files are NOT in git.** `configure`, every
+  `Makefile.in`, `config.h.in`, `ltmain.sh`, `config.guess/sub`, and the aux
+  scripts are build products: `.gitignore`d, regenerated by `./bootstrap`, and
+  shipped only in `make dist` tarballs (so tarball users still need no
+  autotools). Never commit them. After editing `configure.ac`, any
+  `Makefile.am`, or `m4/`, just commit those sources — re-run `./bootstrap`
+  locally to rebuild and test, but do not stage the regenerated output.
+- **Format only changed lines** with `git clang-format` (clang-format 19). Never
+  reformat untouched code: the engine was formatted by an old tool and won't
+  round-trip.
+- **Byte-safe edits.** Files with raw high bytes are ISO-8859-1 (French
+  comments). Edit them byte-wise (`perl -0pi`, `sed`), not through a tool that
+  re-encodes to UTF-8 and corrupts them.
+
+## Security (HTTrack parses hostile input off the network)
+- Bounds-check every copy. Overflow-safe form: put the untrusted value alone,
+  `untrusted < limit - controlled` — never `controlled + untrusted < limit`,
+  which can wrap and pass.
+
+## Code & prose
+- Be terse. Comment the why, in English; translate French comments you touch.
+- Strip AI tells from prose (em-dash overuse, rule-of-three, filler, vague
+  attributions). Ref: Wikipedia "Signs of AI writing". Claude Code: `/humanizer`.
+- Behavior change → add a test. Fast path: a hidden `httrack -#N` debug
+  subcommand (`htscoremain.c`) driven by a `tests/NN_*.test`, over a slow crawl.
+
+## Review your change adversarially (strongly suggested)
+Before pushing, and when reviewing others, don't skim for bugs:
+- **One invariant at a time.** Name a property the diff must preserve (bounds
+  hold, cache/wire format unchanged, no use-after-free, ABI stable), then
+  construct inputs that would break it. "General correctness" is not a charter.
+- **Audit tests against the spec, not the code.** For each new test ask: "what
+  buggy path would still pass this?" If you can build one, the test is
+  confirmation-biased: assertions copied from observed output lock bugs in.
+- **Risk areas need runtime probes.** Touching hostile-input parsing, struct
+  layout/ABI, cache/wire format, or a security path? A static or unit check
+  isn't enough; exercise the wrong behavior at runtime. Claude Code:
+  `/review-recipe`.
+
+## Commits
+- **Sign-off is mandatory.** Every commit carries a `Signed-off-by` trailer:
+  `git commit -s` (DCO, CI-enforced — unsigned commits are rejected).
+- **Co-Authored-By is mandatory for AI-assisted commits.** Carry a
+  `Co-Authored-By:` trailer naming the assistant. Attribute there, never in a
+  PR-body footer.
+- PRs land as a merge commit; every commit on the branch goes onto master, so
+  keep each commit message clean and meaningful.
+
+## PR descriptions
+- Plain concise prose; lead with what changed and why. No What/Why/How template.
+- Title names the problem, not the implementation.
+- Don't restate the diff — give what it can't show: motivation, context,
+  tradeoffs, risk.
+- Length tracks the change: a typo is one sentence; a security fix earns a writeup.
+- Verify claims against the code before you write them; flag drift, don't repeat it.
+- Don't hard-wrap (GitHub reflows). No "Generated with Claude" footer. Run the
+  prose through `/humanizer`.

+A git checkout ships only the autotools sources, so `./bootstrap` (which runs
+`autoreconf`) regenerates `configure` first; this needs autoconf, automake and
+libtool. Released tarballs already include `configure`, so building from a
+tarball skips `./bootstrap`.

 ```sh
 git clone https://github.com/xroche/httrack.git --recurse-submodules
 cd httrack
+./bootstrap
 ./configure --prefix=$HOME/usr && make -j8 && make install
 ```
+
+Or use the one-shot wrapper (bootstrap + configure + make), which forwards its
+arguments to `configure`:

-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as

+  <description>
+    <p>
+      WebHTTrack is the web interface to HTTrack, an offline browser utility.
+      It downloads a website from the Internet to a local directory, fetching
+      the HTML, images, and other files and rebuilding the site's link
+      structure so you can browse it offline.
+    </p>
+    <p>
+      A step-by-step web interface guides you through choosing the addresses
+      to mirror and the options to apply. Mirrors can be updated in place and
+      interrupted downloads resumed.
+    </p>
+    <p>Typical uses include:</p>
+    <ul>
+      <li>Keeping an offline copy of a website for reading without a connection</li>
+      <li>Archiving or preserving sites and capturing them for later reference</li>
+      <li>Updating an existing local mirror without downloading it again</li>
