feat: resolve partial android cmdline-tools and gem versions to the newest matching release

[viceice]

Changes

Partial versions for more tools, like the previous layers of this stack:

• android-sdk-cmdline-tools: 16 or 16.1 resolves to the newest stable matching cmdline-tools;* package, compared numerically (16.10 beats 16.2). An existing release, like 16, is kept as given, and 16.0 installs the release listed as 16. No match throws.
• Gem tools (bundler, cocoapods, install-gem): a major or major.minor version that isn't a release itself resolves to the newest matching non-prerelease from https://rubygems.org/api/v1/versions/<gem>.json (2 → 2.10.0, 2.5 → 2.5.11). No match throws, and so does a failed lookup, since gem can't install a partial version as given. Like the existing latest lookup, it queries rubygems.org through the CDN and URL replacements.
• Gem installs validate RubyGems version strings (2, 5.2, 6.1.7.10, 7.0.0.rc2) instead of semver, so resolved four-part versions and kept partial versions reach gem.
• install-tool --help and install-gem --help list the new notes, docs/tools.md documents them, and the java and ruby container tests install partial versions.
• nuget's newest-version helper moves to tool-version-resolver.ts as newestVersion and compares every dot-separated segment, so four-part gem versions (6.1.7.10) work independent of the feed order.

📝 Walkthrough

Walkthrough

Partial versions now resolve to matching Android command-line tools and Ruby gem releases. A shared version-selection helper also replaces NuGet’s local helper. Command guidance, tests, and Docker stages cover the updated version handling.

Changes

Partial Version Resolution

Layer / File(s)	Summary
Shared version selection src/cli/install-tool/tool-version-resolver.ts, src/cli/install-tool/tool-version-resolver.spec.ts, src/cli/tools/dotnet/nuget.ts	The new newestVersion helper compares numeric version segments and treats missing segments as zero. The NuGet resolver uses the helper to select a matching release.
Android command-line tools matching src/cli/tools/java/android.ts, src/cli/tools/java/android-partial.spec.ts, test/java/Dockerfile	The Android resolver selects the newest stable package that matches a partial version and excludes the latest alias. It reports an error when no stable match exists. Tests and a Docker stage check partial-version resolution and installation.
Ruby gem matching and install guidance src/cli/tools/ruby/schema.ts, src/cli/tools/ruby/utils.ts, src/cli/tools/ruby/utils.spec.ts, src/cli/tools/ruby/cocoapods.spec.ts, src/cli/command/install-gem.ts, src/cli/command/install-gem.spec.ts, docs/tools.md, test/ruby/Dockerfile	Ruby gem resolution validates version strings and uses RubyGems release metadata to keep exact releases or select matching non-prerelease releases. Lookup or parsing failures preserve the requested partial version. Tests, command usage details, documentation, and Docker stages cover partial versions.
Version help coverage src/cli/install-tool/version-resolvers.spec.ts	The expected version help text now includes android-sdk-cmdline-tools and bundler.

Resolve partial Android cmdline-tools and gem versions

✨ Enhancement 🧪 Tests 📝 Documentation 🕐 40+ Minutes

AI Description

• Resolve partial Android cmdline-tools and gem versions to matching releases while preserving
 existing releases.
• Share numeric version selection with NuGet and accept RubyGems version formats during
 installation.
• Document the behavior and cover resolution, errors, help text, and container installs.

High-Level Assessment

Keep resolution in the existing tool-specific resolvers and share only numeric version selection. This preserves each source's release rules; delegating partial versions to gem or adding a separate resolution layer would complicate installation without addressing the existing gemspec mismatch.

🐞 Bugs (1)

1. Android users get obsolete tool releases 🐞 Bug

Description

The Android partial-version fallback filters matching packages by stable channel but does not
exclude packages whose obsolete flag is set. When no exact version exists, an obsolete package
with the highest matching version is selected and passed to the installer, even if a non-obsolete
matching package is available.

Code

src/cli/tools/java/android.ts[159]

+            (p) => p.channel === 'stable' && matchesPartial(p.version, version),

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Android partial-version fallback can select an obsolete stable package over an available non-obsolete release.

## Fix Focus Areas
- src/cli/tools/java/android.ts[156-162]
- src/cli/tools/java/android-partial.spec.ts[71-108]

## Recommended Fix
Exclude packages marked `obsolete` when selecting the newest stable match, while preserving the existing behavior for explicitly requested releases. Add a test where an obsolete higher version competes with a non-obsolete match.

Resolved findings

1. Gem partial installs miss arm tests ✗ Dismissed

Description

The new partial-version installs for cocoapods and rake in test/ruby/Dockerfile have no
counterparts in test/ruby/Dockerfile.arm64. The arm image builds separate stages using full
versions, so neither partial lookup nor install-gem rake 13 is exercised there; the new amd64
checks also stop at version output.

Code

test/ruby/Dockerfile[161]

+RUN install-tool cocoapods 1

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new partial-version gem smoke tests run only in the amd64 image and check only version output after installation.

## Fix Focus Areas
- test/ruby/Dockerfile[154-169]
- test/ruby/Dockerfile.arm64[34-70]

## Recommended Fix
Add arm64 test stages for partial `cocoapods` and `rake` installs and include them in the final arm64 stage. Where feasible, run a gem operation beyond a version check after installation.

2. Android partial installs miss arm tests ✗ Dismissed

Description

The new 16.0 install in test/java/Dockerfile has no corresponding partial-version install in
test/java/Dockerfile.arm64. The arm image builds separate test stages that never exercise this
resolution path, while the new amd64 check runs only sdkmanager --version after installation.

Code

test/java/Dockerfile[306]

+RUN install-tool android-sdk-cmdline-tools 16.0

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new Android command-line tools partial-version install is exercised only in the amd64 test image, and its post-install check tests only the version command.

## Fix Focus Areas
- test/java/Dockerfile[302-310]
- test/java/Dockerfile.arm64[33-66]

## Recommended Fix
Add a partial-version install stage to the arm64 image and include it in that image's final stage. Exercise an SDK manager operation beyond its version command after the partial install where feasible.
