Each deployment now gets its own Kubernetes namespace (laconic-{deployment_id}).
This provides:
- Resource isolation between deployments on the same cluster
- Simplified cleanup: deleting the namespace cascades to all namespaced resources
- No orphaned resources possible when deployment IDs change
Changes:
- Set k8s_namespace based on deployment name in __init__
- Add _ensure_namespace() to create namespace before deploying resources
- Add _delete_namespace() for cleanup
- Simplify down() to just delete PVs (cluster-scoped) and the namespace
- Fix hardcoded "default" namespace in logs function

Adds support for configuring ACME email for Let's Encrypt certificates
in kind deployments. The email can be specified in the spec under
network.acme-email and will be used to configure the Caddy ingress
controller ConfigMap.

The existing 'image-registry' key is used for pushing images to a remote
registry (URL string). Rename the new auth config to 'registry-credentials'
to avoid collision.

Add ability to configure private container registry credentials in spec.yml
for deployments using images from registries like GHCR.
- Add get_image_registry_config() to spec.py for parsing image-registry config
- Add create_registry_secret() to create K8s docker-registry secrets
- Update cluster_info.py to use dynamic {deployment}-registry secret names
- Update deploy_k8s.py to create registry secret before deployment
- Document feature in deployment_patterns.md
The token-env pattern keeps credentials out of git - the spec references an
environment variable name, and the actual token is passed at runtime.

- Add acme_email_key constant for spec.yml parsing
- Add get_acme_email() method to Spec class
- Modify install_ingress_for_kind() to patch ConfigMap with email
- Pass acme-email from spec to ingress installation
- Add 'delete' verb to leases RBAC for certificate lock cleanup
The acme-email field in spec.yml was previously ignored, causing
Let's Encrypt to fail with "unable to parse email address".
The missing delete permission on leases caused lock cleanup failures.

The previous approach of mounting cri-base.json into kind nodes failed
because we didn't tell containerd to use it via containerdConfigPatches.
RuntimeClass allows different stacks to have different rlimit profiles,
which is essential since kind only supports one cluster per host and
multiple stacks share the same cluster.
Changes:
- Add containerdConfigPatches to kind-config.yml to define runtime handlers
- Create RuntimeClass resources after cluster creation
- Add runtimeClassName to pod specs based on stack's security settings
- Rename cri-base.json to high-memlock-spec.json for clarity
- Add get_runtime_class() method to Spec that auto-derives from
unlimited-memlock setting

- Add pyrightconfig.json for pyright 1.1.408 TOML parsing workaround
- Add NoReturn annotations to fatal() functions for proper type narrowing
- Add None checks and assertions after require=True get_record() calls
- Fix AttrDict class with __getattr__ for dynamic attribute access
- Add type annotations and casts for Kubernetes client objects
- Store compose config as DockerDeployer instance attributes
- Filter None values from dotenv and environment mappings
- Use hasattr/getattr patterns for optional container attributes

Add spec.yml option `security.unlimited-memlock` that configures
RLIMIT_MEMLOCK to unlimited for Kind cluster pods. This is needed
for workloads like Solana validators that require large amounts of
locked memory for memory-mapped files during snapshot decompression.
When enabled, generates a cri-base.json file with rlimits and mounts
it into the Kind node to override the default containerd runtime spec.
Also includes flake8 line-length fixes for affected files.

NodePort example:
```
network:
ports:
caddy:
- 1234
- 32020:2020
```
Replicas example:
```
replicas: 2
```
This also adds an optimization for k8s where if a directory matching the name of a configmap exists in beneath config/ in the stack, its contents will be copied into the corresponding configmap.
For example:
```
# Config files in the stack
❯ ls stack-orchestrator/config/caddyconfig
Caddyfile Caddyfile.one-req-per-upstream-example
# ConfigMap in the spec
❯ cat foo.yml | grep config
...
configmaps:
caddyconfig: ./configmaps/caddyconfig
# Create the deployment
❯ laconic-so --stack ~/cerc/caddy-ethcache/stack-orchestrator/stacks/caddy-ethcache deploy create --spec-file foo.yml
# The files from beneath config/<config_map_name> have been copied to the ConfigMap directory from the spec.
❯ ls deployment-001/configmaps/caddyconfig
Caddyfile Caddyfile.one-req-per-upstream-example
```

Rather than always requesting a certificate, attempt to re-use an existing certificate if it already exists in the k8s cluster. This includes matching to a wildcard certificate.

In kind, when we bind-mount a host directory it is first mounted into the kind container at /mnt, then into the pod at the desired location.
We accidentally picked this up for full-blown k8s, and were creating volumes at /mnt. This changes the behavior for both kind and regular k8s so that bind mounts are only allowed if a fully-qualified path is specified. If no path is specified at all, a default storageClass is assumed to be present, and the volume managed by a provisioner.
Eg, for kind, the default provisioner is: https://github.com/rancher/local-path-provisioner
```
stack: test
deploy-to: k8s-kind
config:
test-variable-1: test-value-1
network:
ports:
test:
- '80'
volumes:
# this will be bind-mounted to a host-path
test-data-bind: /srv/data
# this will be managed by the k8s node
test-data-auto:
configmaps:
test-config: ./configmap/test-config
```
