v5.1.0 chore: prepare release

[vipulnsward]

Summary

• Prepare uploadcare-ruby 5.1.0 with file search and file-tag support.
• Carry the published v5.0.1 release commit forward from 5-0-stable so main has continuous version and changelog history.
• Add focused 5.1.0 release notes with upgrade, compatibility, rollout, and rollback guidance.
• Pin the RubyGems publishing action to the immutable v1.1.0 commit instead of mutable master.

Release highlights

File search

• Search by text, UUID, metadata, MIME type, tags, upload date, size, and image status.
• Sort results, inspect highlights, include appdata, and follow POST-aware pagination without rebuilding search criteria.
• Use either client.files.search or the raw client.api.rest.files.search endpoint.

File tags

• List, replace, add, and remove per-file tags through client.file_tags.
• Apply tags during direct, batch, URL, and multipart uploads.
• Read tags from returned file resources.
• Use raw REST file-tag endpoints when endpoint-level control is needed.

Compatibility

• Backward compatible with uploadcare-ruby 5.0.x.
• Requires Ruby 3.3 or newer, unchanged from 5.0.x.
• No configuration or data migration is required.
• Rollback target: 5.0.1.

Verification

• RSpec: 718 examples, 0 failures.
• Coverage: 95.79% (1707/1782 lines).
• RuboCop: 170 files, 0 offenses.
• RubyGem build: uploadcare-ruby-5.1.0.gem built successfully and reports version 5.1.0.
• Package contents include the changelog, 5.1.0 release notes, and file-search/file-tag examples.
• YARD: 98.5% documented.
• All Ruby examples parse successfully; context7.json and gem-push.yml parse successfully.
• Publishing action pin verified against cadwallion/publish-rubygems-action v1.1.0.

Live Uploadcare API examples were not executed during release prep because API credentials were unavailable. Transport, resource, pagination, normalization, and failure paths are covered by the automated suite.

Release boundary

This PR only prepares the release. It does not create the v5.1.0 tag, publish the gem, or create a GitHub release. After this PR is merged and final release approval is given, pushing v5.1.0 will trigger the existing Publish Gem workflow.

Walkthrough

The release updates the SDK to version 5.1.0, adds release and migration documentation, updates version tests and examples, and configures the gem publishing workflow with write permission and a pinned action commit.

Changes

Release preparation

Layer / File(s)	Summary
Version metadata and release documentation lib/uploadcare/version.rb, spec/uploadcare/version_spec.rb, lib/uploadcare/internal/user_agent.rb, CHANGELOG.md, docs/release-notes-5.1.0.md	The SDK version and version test now use 5.1.0. The User-Agent example, changelog, and release notes describe the 5.1.0 release.
Migration guidance MIGRATING_V5.md	Migration guidance now includes client.file_tags and Uploadcare::FileTags.
Gem publishing workflow .github/workflows/gem-push.yml	The build job requests contents: write permission. The release workflow uses the fixed v1.1.0 commit of cadwallion/publish-rubygems-action instead of master.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 93bb2

The release publishing workflow may grant a broader GitHub token permission set than required, increasing the impact of a compromised or misused release job. The release preparation is otherwise ready, but this permission scope should be intentionally constrained or accepted before merge.
