Embeds ezbake functionality into kiln as a carvel subcommand

Embeds ezbake functionality into kiln as a Go library, adding full
lifecycle support for baking, uploading, publishing, and reproducibly
re-baking Carvel/Kubernetes tiles.

### New commands

- **`kiln carvel bake`** — Transforms an imgpkg bundle into a BOSH
release and bakes it into a `.pivotal` file. When a `Kilnfile.lock` is
present, downloads the cached BOSH release from Artifactory instead of
regenerating locally.
- **`kiln carvel upload`** — Generates a BOSH release from Carvel tile
source, uploads the tarball to Artifactory, and writes `Kilnfile.lock`
with the remote location and checksum.
- **`kiln carvel publish`** — Bakes a final tile with version stamping
and produces a JSON bake record for reproducible builds.
- **`kiln carvel re-bake`** — Reproduces a tile build from a bake
record, verifying source revision matches the git checkout.

### New packages

- **`internal/carvel`** — Core `Baker` that reads tile metadata
(`base.yml`) and imgpkg bundles, generates a BOSH release via `bosh
create-release`, creates a kiln-compatible structure in `.ezbake/`, and
invokes `kiln bake` to produce the final `.pivotal` file.
- **`internal/carvel/models`** — Data models for tile metadata, Carvel
lockfiles, package installs, runtime configs, and jobs.

### Architecture

The `kiln carvel` command group is registered in `main.go` and delegates
to subcommands via `jhanda.CommandSet`. Each subcommand uses the
standard `flags.Standard` embedded struct to load Kilnfiles with
variable interpolation (e.g., from `~/.kiln/credentials.yml`), keeping
credential handling consistent with existing kiln commands. The `Baker`
interface drives the imgpkg-to-BOSH transformation and tile assembly.

### Other changes

- **Consistent lockfile serialization** — `CarvelLockfile` now uses
`releases` (plural, as a slice) instead of `release` (singular),
matching the standard `KilnfileLock` format in `pkg/cargo`.
- **CI lint fixes** — Resolved all `staticcheck` and `unused` findings
across the new files (capitalized error strings, redundant embedded
field selectors, unnecessary `fmt.Sprintf`, unused functions).
- **CI test stability** — Test `BeforeEach` blocks that run `git commit`
now pass `-c user.name` / `-c user.email` inline so they work on CI
runners without global git config.
- **Acceptance and unit tests** — Full test coverage for all four
subcommands, the `Baker`, and the Carvel model types.

## Usage

```sh
# Bake a Carvel tile locally
kiln carvel bake --source-directory /path/to/tile --output-file tile.pivotal

# Upload the BOSH release to Artifactory (writes Kilnfile.lock)
kiln carvel upload --source-directory /path/to/tile --kilnfile /path/to/Kilnfile

# Publish a versioned tile and produce a bake record
kiln carvel publish --source-directory /path/to/tile --output-file tile.pivotal --version 1.0.0 --final

# Reproduce a tile from a bake record
kiln carvel re-bake --output-file tile.pivotal bake-record.json
```

## Test plan

- [x] `go test ./internal/carvel/...` — Baker and model unit tests
- [x] `go test ./internal/commands/...` — All carvel subcommand tests
(bake, upload, publish, re-bake)
- [x] `go test ./internal/acceptance/carvel/...` —
Integration/acceptance tests
- [x] `golangci-lint run ./...` — Zero lint issues

v0.110.0

• Removes use of sessions from image building in Kiln test in order to improve compatibility with Podman
• Fixes variable file default discovery for nested tiles in re-bake See #538

v0.109.0

fix: variable file default discovery for nested tiles (#538)

There's a bug where Kiln `re-bake` wasn't accounting for the relative
tile / Kilnfile path when automatically discovering variable files.
Since `re-bake` relies heavily on convention in typical use, we'd like
to fix this.

### Reproducing the bug

I forked `hello-tile` and modified it to have a nested tile directory
with a single variable `$( variable "hellothere" )` to be interpolated
in its `base.yml`. I created a variables file under
`nest/variables/hellothere.yml` defining its namesake.

It's expected at this point that we need to pass the `--variables-file`
explicitly because `kiln` doesn't know about the nesting yet:

**Creating the record**
```sh
kiln bake --final --version 6 \
   --vr artifactory_host=<redacted> \
   --vr artifactory_repo=<redacted> \
   --vr artifactory_username=<redacted> \
   --vr artifactory_password=<redacted> \
--metadata nest/base.yml \
--icon=nest/icon.png \
--kilnfile nest/Kilnfile \
--variables-file nest/variables/hellothere.yml
Setting default credentials from ~/.kiln/credentials.yml. (hint: --variable-file overrides this default. --variable overrides both.)
Warning: The "allow-only-publishable-releases" flag was not set. Some fetched releases may be intended for development/testing only. EXERCISE CAUTION WHEN PUBLISHING A TILE WITH THESE RELEASES!

Creating empty migrations folder in tile-6.pivotal...
Adding releases/hello-release-1.0.5-ubuntu-jammy-1.737.tgz to tile-6.pivotal…
```

This is expected behavior.

Then we find the bug:

**Re-baking the record**
```sh
mv nest/bake_records/6.json /tmp/6.json
mv tile-6.pivotal ~/workspace/tilediff/tile-6-new.zip

kiln re-bake --output-file /tmp/tile-6-rebake.pivotal /tmp/6.json
Setting default credentials from ~/.kiln/credentials.yml. (hint: --variable-file overrides this default. --variable overrides both.)

```

### The fix

Essentially we're including the nested directory when available during
our variable files search. We define

```go
func getVariablesDir(fs flags.FileSystem, kilnfilePath string) string
```

and then use it during the search:

```go
func getVariablesFilePaths(fs flags.FileSystem, kilnfilePath string) ([]string, error) {
	variablesDirPath := getVariablesDir(fs, kilnfilePath)
	files, err := fs.ReadDir(variablesDirPath)
...
```

and 

```go
func variablesDirPresent(fs flags.FileSystem, kilnfilePath string) bool {
	variablesDirPath := getVariablesDir(fs, kilnfilePath)
	file, err := fs.Stat(variablesDirPath)
...
```

### Testing the fix

Let's build this branch as `kiln-dev` and then re-run the above commands
in an equivalent way:

**Creating the record**
```sh
kiln-dev bake --final --version 6 \
   --vr artifactory_host=<redacted> \
   --vr artifactory_repo=<redacted> \
   --vr artifactory_username=<redacted> \
   --vr artifactory_password=<redacted> \
--metadata nest/base.yml \
--icon=nest/icon.png \
--kilnfile nest/Kilnfile
Setting default credentials from ~/.kiln/credentials.yml. (hint: --variable-file overrides this default. --variable overrides both.)
