Update mcdsl from v1.0.1 to v1.0.2-0.20260327074919-f94c4b1abf9c
(port-env-support branch) which adds $PORT environment variable
support for HTTP and gRPC server configuration.

Replace metacrypt's hand-rolled gRPC interceptor chain with the mcdsl
grpcserver package, which provides TLS setup, logging, and method-map
auth (public/auth-required/admin-required) out of the box.
Metacrypt-specific interceptors are preserved as hooks:
- sealInterceptor runs as a PreInterceptor (before logging/auth)
- auditInterceptor runs as a PostInterceptor (after auth)
The three legacy method maps (seal/auth/admin) are restructured into
mcdsl's MethodMap (Public/AuthRequired/AdminRequired) plus a separate
seal-required map for the PreInterceptor. Token context is now stored
via mcdsl/auth.ContextWithTokenInfo instead of a package-local key.
Bumps mcdsl from v1.0.0 to v1.0.1 (adds PreInterceptors/PostInterceptors
to grpcserver.Options).

Replace local TOML loading with mcdsl/config.Load[Config] which adds
METACRYPT_ environment variable overrides. ServerConfig and MCIASConfig
now embed their mcdsl counterparts, extending with ExternalURL and
ServiceToken respectively. DatabaseConfig and LogConfig replaced with
mcdsl types directly.
TOML structure is preserved — no config file changes needed.

- db.Open: delegate to mcdsl/db.Open
- db.Migrate: convert to mcdsl/db.Migration format, delegate
- auth: type aliases for TokenInfo/Authenticator/Config from mcdsl,
re-export error sentinels, Logout helper
- cmd/server: construct auth.Authenticator from Config (not mcias.Client)
- server/routes.go logout: use auth.Logout(authenticator, token)
- grpcserver/auth.go: same logout pattern, fix Login return type
(time.Time not string)
- webserver: replace mcias.Client with mcdsl/auth for service token
validation; resolveUser degrades to raw UUID (TODO: restore when
mcias client library is properly tagged)
- Dockerfiles: bump to golang:1.25-alpine, remove gcc/musl-dev,
add VERSION build arg
- Deploy: add docker-compose-rift.yml with localhost-only port mapping
- Remove git.wntrmute.dev/kyle/mcias/clients/go dependency entirely
- All tests pass, net -185 lines

- Fix#61: handleRotateKey and handleDeleteUser now zeroize stored
privBytes instead of calling Bytes() (which returns a copy). New
state populates privBytes; old references nil'd for GC.
- Add audit logging subsystem (internal/audit) with structured event
recording for cryptographic operations.
- Add audit log engine spec (engines/auditlog.md).
- Add ValidateName checks across all engines for path traversal (#48).
- Update AUDIT.md: all High findings resolved (0 open).
- Add REMEDIATION.md with detailed remediation tracking.

- Add PUT /v1/policy/rule endpoint for updating policy rules; expose
full policy CRUD through the web UI with a dedicated policy page
- Add certificate revoke, delete, and get-cert to CA engine and wire
REST + gRPC routes; fix missing interceptor registrations
- Update ARCHITECTURE.md to reflect v2 gRPC as the active implementation,
document ACME endpoints, correct CA permission levels, and add policy/cert
management route tables
- Add POLICY.md documenting the priority-based ACL engine design
- Add web/templates/policy.html for policy management UI

The vault server holds in-memory unsealed state (KEK, engine keys) that
is lost on restart, requiring a full unseal ceremony. Previously the web
UI ran inside the vault process, so any UI change forced a restart and
re-unseal.
This change extracts the web UI into a separate metacrypt-web binary
that communicates with the vault over an authenticated gRPC connection.
The web server carries no sealed state and can be restarted freely.
- gen/metacrypt/v1/: generated Go bindings from proto/metacrypt/v1/
- internal/grpcserver/: full gRPC server implementation (System, Auth,
Engine, PKI, Policy, ACME services) with seal/auth/admin interceptors
- internal/webserver/: web server with gRPC vault client; templates
embedded via web/embed.go (no runtime web/ directory needed)
- cmd/metacrypt-web/: standalone binary entry point
- internal/config: added [web] section (listen_addr, vault_grpc, etc.)
- internal/server/routes.go: removed all web UI routes and handlers
- cmd/metacrypt/server.go: starts gRPC server alongside HTTP server
- Deploy: Dockerfile builds both binaries, docker-compose adds
metacrypt-web service, new metacrypt-web.service systemd unit,
Makefile gains proto/metacrypt-web targets

Implements the SystemService gRPC endpoint (Status, Init, Unseal, Seal)
alongside the existing REST API, secured with the same TLS certificate.
The `metacrypt unseal` CLI command now prefers gRPC when --grpc-addr is
provided, falling back to the REST API via --addr. Both transports require
TLS; a custom CA certificate can be supplied with --ca-cert.
Server changes:
- internal/server/grpc.go: SystemServiceServer implementation with
StartGRPC/ShutdownGRPC methods; uses the TLS cert from config.
- internal/server/server.go: adds grpcSrv field and grpc import.
- cmd/metacrypt/server.go: starts gRPC goroutine when grpc_addr is set
in config, shuts it down on signal.
Generated code (from proto/metacrypt/v1/system.proto):
- gen/metacrypt/v1/system.pb.go: protobuf message types
- gen/metacrypt/v1/system_grpc.pb.go: gRPC client/server stubs
Dependencies added to go.mod (run `go mod tidy` to populate go.sum):
- google.golang.org/grpc v1.71.1
- google.golang.org/protobuf v1.36.5
- google.golang.org/genproto/googleapis/rpc (indirect)
- golang.org/x/net (indirect)

- Add ARCHITECTURE.md with full system specification
- Add Project Structure and API Sync Rule to CLAUDE.md; ignore srv/
- Fix engine.proto MountRequest missing config field
- Add pki.proto PKIService to match unauthenticated REST PKI routes

Add the first concrete engine implementation: a CA (PKI) engine that generates
a self-signed root CA at mount time, issues scoped intermediate CAs ("issuers"),
and signs leaf certificates using configurable profiles (server, client, peer).
Engine framework updates:
- Add CallerInfo struct for auth context in engine requests
- Add config parameter to Engine.Initialize for mount-time configuration
- Export Mount.Engine field; add GetEngine/GetMount on Registry
CA engine (internal/engine/ca/):
- Two-tier PKI: root CA → issuers → leaf certificates
- 10 operations: get-root, get-chain, get-issuer, create/delete/list issuers,
issue, get-cert, list-certs, renew
- Certificate profiles with user-overridable TTL, key usages, and key algorithm
- Private keys never stored in barrier; zeroized from memory on seal
- Supports ECDSA, RSA, and Ed25519 key types via goutils/certlib/certgen
Server routes:
- Wire up engine mount/request handlers (replace Phase 1 stubs)
- Add public PKI routes (/v1/pki/{mount}/ca, /ca/chain, /issuer/{name})
for unauthenticated TLS trust bootstrapping
Also includes: ARCHITECTURE.md, deploy config updates, operational tooling.
