0fc4600d07 fix(#2332): add After=hive-tls-ca to resign service — prevent first-boot CA race
On a fresh deploy Persistent=true causes the weekly timer to fire
immediately. Without this ordering hive-tls-resign can race
hive-tls-ca before the CA key is written, failing the resign.
CA is always valid when this runs; resign is a no-op if the leaf
is still within its half-life margin.

Suggested by argus (review) + requested by mara.

61bd0b604d feat(#1933): weekly hive-tls-resign timer — dedicated resign service, no hive-tls-ca bounce
The parked PR (#1934) triggered re-sign by restarting hive-tls-ca
(a RemainAfterExit oneshot), which mara flagged as a hack.  This
replaces that with a dedicated hive-tls-resign.{service,timer}:

- hive-tls-ca unchanged — still handles boot-time CA generation +
  initial leaf signing; RemainAfterExit, runs before the gateway.
- hive-tls-resign.service — runs the leaf re-sign directly (openssl
  in its own PATH); does NOT touch hive-tls-ca.  Re-signs only when
  the leaf is within half its validity of expiry, so the weekly timer
  catches short-lived (30d default) leaves well before they lapse.
  Checks sha256 before/after; if the leaf rotated it propagates into
  the running gateway via systemctl -M hive-gateway (mirroring how
  hive-c0re reloads the gateway after agents.conf writes — the
  documented correct approach; an inotify path unit inside the
  container does not work across the nspawn mount-namespace boundary).
  || true on the propagation calls so a stopped gateway never fails
  the unit (its next boot imports the already-rotated leaf).
- hive-tls-resign.timer — OnCalendar=weekly, Persistent=true (fires a
  missed run on next boot so a host that was off on the scheduled day
  catches up rather than letting the leaf lapse silently).
- leafValidityDays doc updated to reflect automatic renewal.

Closes #1933.

14ae7367cd fix(systemd): set explicit SyslogIdentifier on hyperhive-declared units
Follow-up to the harness fix: any unit whose ExecStart is a generated
wrapper (a NixOS `script =` block or a writeShellScript) gets its journal
SyslogIdentifier derived from the wrapper's store-path basename — an
opaque, unstable name. Pin an explicit stable identifier on every unit
hyperhive declares.

script/wrapper units (leaked store paths): forgejo-gpg-init,
hive-gateway-self-signed-cert, hive-tls-ca, hive-ci-prefetch,
hyperhive-isolated-dns, tea-login, forge-avatar-sync,
matrix-avatar-sync, hive-dashboard-links.

direct-binary units (basename already sane; explicit for tidiness +
future-proofing): hive-c0re, hive-priv, hive-matrix-daemon,
hive-bash-daemon, weston.

Only changes the displayed line identifier; journalctl -u <unit>
filtering (keys on _SYSTEMD_UNIT) is unaffected.

4e4e9f8a60 hive-tls: leafValidityDays default 30 (per mara: ahead of the ~47-day proposal)
Short-lived leaf bounds the blast radius of a key compromise. Doc notes
the renewal caveat: re-sign is activation-only today, so a hive that
stays up >30 days without a rebuild would need a periodic re-sign timer
to avoid leaf expiry (follow-up).

5ed0288634 hive-tls: default leafValidityDays to 397 (was 3650/~10y)
A 10-year leaf is pointless given the leaf auto-rotates (re-signed
within 30 days of expiry) and is long enough to make browsers warn.
397 days sits just under the 398-day CA/Browser-Forum leaf cap (so
browsers accept it) while bounding the blast radius of a leaf-key
compromise. The re-sign runs at service activation (hive-tls-ca is a
oneshot, no timer), so 397 stays comfortably above any gateway
rebuild gap.

3b8e77c1c1 nix(gateway): factor the self-signed condition into a shared option
Per review: the `tls.certDir == null && !tls.acme.enable` derivation was
duplicated in hive-gateway, hive-tls, and hive-ci. Expose it once as a
read-only internal option `services.hyperhive.gateway.useSelfSigned` (the
gateway module's single source of truth) and have hive-tls and hive-ci
consume it instead of re-deriving.

Eval-proven: gateway.useSelfSigned is true on the self-signed default /
false with tls.certDir, and the hive-tls (HIVE_TLS_CA_PATH) + hive-ci
(NODE_EXTRA_CA_CERTS) wiring derives correctly from it.

1a3f82a459 nix(gateway): self-signed TLS as the implicit default, deprecate the toggle
Make self-signed TLS the gateway's default whenever no external TLS source
is configured, and deprecate the explicit selfSignedTls toggle. Self-signed
is now derived as `tls.certDir == null && !tls.acme.enable`, so an operator
selects a TLS mode by setting tls.certDir or tls.acme — or neither, for the
self-signed default. There is no http-only mode: matrix discovery hardcodes
https, so the gateway always terminates TLS.

The selfSignedTls option is kept as a deprecated no-op (warns when set to
false) so existing configs still eval. The two selfSignedTls mutual-
exclusion assertions and the HSTS-requires-TLS assertion are dropped — they
are impossible or vacuous now that self-signed is the floor. The hive-tls
module and the forge ROOT_URL scheme consume the derived value: the gateway
always terminates TLS, so behind the gateway the forge is always advertised
over https.

Updates docs/gateway.md (TLS-modes table, self-signed section, the removed
http-only section, firewall + discovery notes). Eval-proven: default →
self-signed (hive CA active, https ROOT_URL); tls.certDir → CA inactive;
selfSignedTls=false → deprecation warning fires.

4f3f6522d2 feat(tls): embed hive CA into agent flakes for self-signed trust
Wire agents to trust the gateway's self-signed leaf at build time. When
the gateway runs self-signed TLS, hive-tls sets HIVE_TLS_CA_PATH in
hive-c0re's service env pointing at the host hive CA cert. The meta flake
renderer reads it and, when present, writes the public CA cert next to
flake.nix as hive-ca.pem and emits security.pki.certificateFiles so every
agent's system trust store includes the hive CA.

Build-time embedding (rather than a runtime bind-mount + bundle service)
keeps trust robust: the CA travels with the flake source, lands in the
standard NixOS trust store, and needs no per-process SSL_CERT_FILE
plumbing. Only the public CA certificate is embedded; the CA private key
never leaves the host. The cert is re-embedded and re-committed on CA
rotation even when the flake is otherwise byte-identical; when self-signed
TLS is off the embedded cert is dropped so the flake stays buildable.

Covers OpenSSL-based tools (git, curl) directly. A follow-up switches the
hive-forge reqwest client to native roots so it picks up the same store.

74a90fd7d6 nix(tls): host hive-CA + gateway leaf for self-signed mode
Replace the gateway's bare in-container self-signed leaf with a leaf
signed by a host-held hive CA. A bare self-signed leaf is its own trust
anchor, so every regeneration is a fresh anchor every consumer would have
to re-trust, and a runtime-generated in-container leaf cannot be wired
into an agent's build-time trust store at all. A stable CA fixes both: a
single anchor that agents and federation peers trust once, surviving leaf
rotation.

New hive-tls module: a host oneshot generates a long-lived CA (default
~20y) under services.hyperhive.tls.stateDir and signs a gateway leaf
(default ~10y, SAN covering the bare domain, forge., matrix. and the
wildcard). It is ordered before the gateway container so the leaf exists
when nginx starts. Active only when the gateway uses self-signed TLS
(default) and a domain is set; inert under operator-cert or ACME modes.

Gateway: bind-mount the host CA dir read-only at /run/hive-ca; the
existing in-container cert unit now imports the host leaf into nginx's
state dir (copy as root, key left root:nginx 0640 for the pre-start
config test) instead of generating one. Cert/key paths nginx serves are
unchanged.

Foundational step toward agent + federation trust of self-signed hives;
no behaviour change for agents yet (they still reach the forge over plain
http on port 80). Eval-proven across self-signed, certDir and the inert
default paths.
