Adds a configurable maximum repository count per registry instance.
When maxRepos is set on StorageConfig, manifest pushes that would create
a new repository beyond the limit are rejected with HTTP 429
TOOMANYREQUESTS. Pushes to existing repositories are always allowed.
Implemented as an always-available feature in pkg/api (not a build-tag
extension). MaxRepos is a field on StorageConfig, enabled when > 0.
- repoQuotaMiddleware on the dist-spec router intercepts manifest PUTs.
New-repo pushes are serialized with a sync.Mutex to prevent concurrent
requests from exceeding the limit.
- Adds CountRepos(ctx) to the MetaDB interface with efficient
implementations: BoltDB (Stats().KeyN), Redis (HLen), DynamoDB
(Scan with Select=COUNT).
- Config.IsQuotaEnabled() added, wired into controller.go metaDB init.
- Four integration tests (enforcement, concurrency, disabled,
unconfigured) and backend-specific CountRepos tests for BoltDB, Redis,
and DynamoDB.

* refactor: Refactor upgrade tests to improve readability and maintainability
- Added section headers for release tests, upgrade process, and new tests in upgrade.bats and upgrade_minimal.bats.
- Replaced inline port retrieval with a function call to get_zot_port for consistency.
- Consolidated repeated test logic into dedicated functions (e.g., test_new_existing_pull_image, test_new_push_image).
- Removed unnecessary variable assignments and streamlined test cases for clarity.

feat: add support for sha256 and sha512 htpasswd formats
Fixes issue #3495
We currently support only bcrypt htpasswd hashes, however bcrypt is not
FIPS-140 approved since it uses Blowfish.
This PR adds support for sha256 and sha512 formats and enforces that
bcrypt be disabled when fips140 mode is enabled.

Description
====================
zot currently stores session cookies in memory or in a local directory.
For cases where the session cookies should be independent of the
instance where they were created such as multiple instances of zot, or a
fully stateless zot instance, there is a need to support a remote
session storage.
This change adds support for using Redis and Redis-compatible services as a
remote session driver as well as introduces a new configuration option
for it.
What has changed
=======================
- New config added under Auth config to specify configuration for
the session driver.
- Examples README updated with details of the new Auth config.
- The config supports only 2 drivers in this change - local and redis
- Using the local driver is backwards compatible and behaves the same
way that zot currently works for local session storage.
- Omitting this config does not result in an error. In this case, zot
behaves as it normally does for local session storage.
- When configured, zot can use redis for persisting cookie
information for zot UI.
- The cookie in the store is deleted on logout or after the max
expiry time for the cookie.
- Configuration for the redis session driver accepts the same configuration
values as that of the remote meta cache.
- A separate connection is established for the session driver. An
existing connection for meta cache will not be re-used for the
session driver.
- A key prefix is configurable for the redis session driver. The value will be
converted into a string for use. If no value is provided, a default
prefix of "zotsession" will be used.
- Redis sessions does not support hash key or encryption in this change.
- New BATS test added to verify zot behavior with Redis session store.
- Github workflow updated to install valkey-tools dependency for BATS.

Fixes https://github.com/project-zot/zot/issues/2004
* feat: add redis cache support
Currently, we have dynamoDB as the remote shared cache but ideal only
for the cloud use case.
For on-prem use case, add support for redis.

* feat: add support for docker images
Issue #724
A new config section under "HTTP" called "Compat" is added which
currently takes a list of possible compatible legacy media-types.
https://github.com/opencontainers/image-spec/blob/main/media-types.md#compatibility-matrix
Only "docker2s2" (Docker Manifest V2 Schema V2) is currently supported.
Garbage collection also needs to be made aware of non-OCI compatible
layer types.
