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.

1. Parse repos without metadata in ParseStorage
The timestamp check in ParseStorage was skipping repos that exist in
storage but don't have metadata. When GetRepoLastUpdated returns zero
time (no metadata), we should always parse the repo to create its
metadata. Check if metaLastUpdated is zero before comparing timestamps.
If zero, always parse regardless of storageLastUpdated.
2. Change the logic of how LastUpdated is computed in RepoSummary
It is not the latest tagged timestamp from the available images or
the last updated image created timestamp, based on whichever is the
latest.

feat(meta): add TaggedTimestamp field and preserve during re-parsing
Add TaggedTimestamp field to track when image tags were created, exposed
through GraphQL API. Previously, when zot restarted and re-parsed storage,
ResetRepoReferences would clear all tags, causing timestamp information to
be lost and reset to the service restart time for existing images.
This change adds TaggedTimestamp support and modifies ResetRepoReferences to
selectively preserve tags that still exist in storage, maintaining their
TaggedTimestamp values. Tags that no longer exist in storage are removed as
before.
Changes:
- Add TaggedTimestamp field to GraphQL ImageSummary schema
- Update GraphQL conversion functions to populate TaggedTimestamp with
fallback to PushTimestamp when unavailable
- Updated ResetRepoReferences interface to accept tagsToKeep parameter
- Modified ParseRepo to collect tags from storage before resetting
- Updated all backend implementations (Redis, DynamoDB, BoltDB) to preserve
tags in tagsToKeep instead of clearing all tags
- Updated tests and mocks to match new signature
This ensures TaggedTimestamp accurately reflects when tags were originally
created, and exposes this information through the GraphQL API.

fix: error handling: return nil explicitly on successful completion
Several functions in pkg/meta/redis/redis.go were returning 'err' at the
end of successful execution paths, which could lead to incorrect error
handling when 'err' was overwritten in loops or conditionals.
Changed the following functions to return nil explicitly when all
operations succeed:
- SearchRepos: return nil instead of err after successful loop
- SearchTags: return nil instead of err after successful loop
- GetRepoMeta: return nil instead of err after successful operations
- GetImageMeta: return nil instead of err after successful operations
- GetReferrersInfo: return nil instead of err after successful loop
This ensures that when functions complete successfully, they explicitly
return nil rather than relying on the last value of err, which may have
been overwritten during execution. This fixes TestRedisUnreachable which
was failing because SearchRepos was incorrectly returning nil error when
Redis was unreachable.

fix: make sure metadb statistics are initialized on image download, and minor metadb fixes for Docker v2 manifest compatibility
Looking into potential causes of https://github.com/project-zot/zot/issues/3163
1. One possible reason is the statistics were not properly initialized in the first place because of (unknown and/or unavoidable) errors on image push.
To workaround this add logic to initialize the statistics on the call to download them.
2. Some images have the download statistics while others dont, one cause could be a bug in the logic handling manifest mediatypes in the search extension.
Add compatibility checks for Docker v2 manifest types in metadb convert functions, and more tests for covering the Docker mediatype use case.
Side fixes:
- Ensure PushedBy Statistics entries are properly initialized in SetRepoReference
- Fix and issue in the image upload test functions, they were uploading docker images with oci mediatypes in call headers

GC and scrub should not stop if a manifest or index is missing from storage.
Other similar changes are also included.
WRT metadb, the missing manifests cannot be added, and the results returned from metadb
do not include the descriptors for these manifests.

See: https://github.com/project-zot/zot/issues/2506
Note we are not loosing anything functionality-wise by making this change.
Initially we considered the tags are in the annotations present in the referrers
but the only annotations we set on referrers are the ones inside the manifests themselves,
not the ones in the manifest descriptors, so the tags were not presetn anyway.

* fix: migrate to Go module v2 for proper semantic versioning
This change updates the module path from 'zotregistry.dev/zot' to
'zotregistry.dev/zot/v2' to comply with Go's semantic versioning rules.
According to Go's module versioning requirements, major version v2+
must include the major version in the module path. The current
module path 'zotregistry.dev/zot' only supports v0.x.x and v1.x.x
versions, making existing v2.x.x tags (like v2.1.8) unusable.
Changes:
- Updated go.mod module path to zotregistry.dev/zot/v2
- Updated all internal import paths across 280+ Go source files
- Updated configuration files (golangcilint.yaml, gqlgen.yml)
- Updated README.md Go reference badge
This fix enables proper use of existing v2.x.x Git tags and allows
external packages to import zot v2+ versions without compatibility
errors.
Resolves: Go module import compatibility for v2+ versions
Fixes: #3071
