certctl dev 099683daba v2.0.48: swap self-signed TLS bootstrap algorithm ed25519 → ECDSA-P256
Follow-up to v2.0.47 (HTTPS-Everywhere). The Phase-3 self-signed
bootstrap sidecar shipped an ed25519 server cert. Apple's TLS stack —
Safari Network Framework and the macOS-bundled LibreSSL 3.3.6
/usr/bin/curl — does not advertise ed25519 in the ClientHello
signature_algorithms extension for server certs, so the handshake fails
with the server-side log line:

  tls: peer doesn't support any of the certificate's signature algorithms

Homebrew OpenSSL 3.x, Chrome, Firefox, and Linux curl all accept
ed25519 server certs fine. Apple is the outlier. Rather than gate the
demo stack behind "install Homebrew OpenSSL first," swap the bootstrap
algorithm to ECDSA-P256 with SHA-256 — universally supported, including
on the Apple stack.

Changes
- deploy/docker-compose.yml: certctl-tls-init openssl invocation swapped
  to `-newkey ec -pkeyopt ec_paramgen_curve:P-256 -nodes`; header comment
  + echo line updated; multi-line rationale paragraph added.
- deploy/docker-compose.test.yml: same openssl swap + echo update for
  the test harness sidecar that writes to the bind-mounted ./test/certs
  directory the Go integration_test.go pins via CERTCTL_TEST_CA_BUNDLE.
- docs/tls.md: Pattern 1 description + code block updated;
  "Why ECDSA-P256 and not ed25519" rationale paragraph added covering
  pre-v2.0.48 history, the Apple diagnosis, accepting clients, and
  the operator migration command. Patterns 2 (existing Secret) and 3
  (cert-manager) explicitly called out as unaffected.
- docs/upgrade-to-tls.md: docker-compose procedure sentence updated
  with cross-reference to tls.md Pattern 1.
- docs/test-env.md: "Get the CA bundle for curl" sentence updated.

Migration
Existing demo installs must tear the `certs` named volume down to pick
up the new algorithm:

  docker compose -f deploy/docker-compose.yml down -v
  docker compose -f deploy/docker-compose.yml up -d --build

Not touched
- cmd/server/tls.go: algorithm-agnostic. TLS 1.3 min version with
  [X25519, P-256] curve preferences for key exchange is orthogonal to
  the server cert's signature algorithm. No Go code change needed.
- Helm chart: Patterns 2 and 3 operators supply their own cert; this
  patch does not affect them.
- Unrelated ed25519 uses (agent key algorithm detection, profile
  algorithm options, SSH key path examples, tlsprobe key metadata,
  cloud discovery key-algo display): all orthogonal to the server TLS
  bootstrap cert.

Incidental cleanup
- .gitignore: dropped dangling `strategy.md` entry (file doesn't exist
  in repo; entry was cruft).

# =============================================================================
# certctl Testing Environment — Docker Compose
# =============================================================================
#
# Spins up the full certctl platform with real CA backends for manual QA:
#
# 0. certctl-tls-init — one-shot init container; writes self-signed
# server.crt/.key/ca.crt into ./test/certs (bind
# mount, not a named volume — host-readable for
# the Go integration test binary)
# 1. PostgreSQL 16 — database (clean, no demo data)
# 2. certctl-server — control plane API + web dashboard on :8443 (HTTPS)
# 3. certctl-agent — polls for work, deploys certs to NGINX
# 4. step-ca — private CA (JWK provisioner, auto-bootstraps)
# 5. Pebble — ACME test server (simulates Let's Encrypt)
# 6. pebble-challtestsrv — DNS/HTTP challenge test server for Pebble
# 7. NGINX — TLS target server on :8080 (HTTP) / :8444 (HTTPS)
#
# Usage:
# cd deploy
# docker compose -f docker-compose.test.yml up --build
#
# Dashboard: https://localhost:8443 (self-signed — use --cacert test/certs/ca.crt)
# API key: test-key-2026
# NGINX: https://localhost:8444 (self-signed placeholder until cert deployed)
#
# Integration tests: `go test -tags integration ./deploy/test/...` picks up
# the CA bundle at ./test/certs/ca.crt automatically via CERTCTL_TEST_CA_BUNDLE.
#
# See docs/test-env.md for the full walkthrough.
# =============================================================================

# HTTPS-Everywhere Phase 6 — self-signed TLS bootstrap for the test harness.
# ---------------------------------------------------------------------------
# Mirrors the production `certctl-tls-init` (see docker-compose.yml §10-43)
# but writes into a *host bind mount* (./test/certs) instead of a named
# volume. The named-volume approach works fine inside Docker but hides the
# CA bundle from the Go integration test binary that runs on the host; the
# bind mount exposes /etc/certctl/tls/ca.crt at deploy/test/certs/ca.crt
# so `newTestClient()` can load it into an x509.CertPool and validate the
# self-signed server cert. Test-only divergence, explicitly documented.
#
# The generated cert has SAN=DNS:certctl-server,DNS:localhost,IP:127.0.0.1
# so both in-cluster traffic (agent → certctl-server:8443) and host traffic
# (go test → localhost:8443) validate cleanly. Destroy via
# `docker compose -f docker-compose.test.yml down -v` + `rm -rf test/certs`
# to force regeneration. Keys written 0600, certs 0644, owned 1000:1000
# (the UID the server binary runs as inside its container per Dockerfile:64).
