refactor: consume character focus from RPCharacters

[ryanbarlow97]

Use RPCharacters.getFocusService() directly for experiment costs, balance display and grants. Replace the Core Maven/runtime dependency with RPCharacters 2.1.0.

Validation: baseline and final Maven builds passed (no existing tests); runtime JAR checks passed. Final verification used the source-built RPCharacters candidate.

Provider dependency: RPCharacters 2.1.0 is now published; pinned-release CI has been rerun against that artifact. Operators handle the server file copies manually as documented in Docs.

2. Focus: RPCharacters #27, Research #4, Magic #24 (also scanner).
3. Letters: BirdMessenger #24.
4. Core removal and manual update guide: TFMCCore #24, Docs #45.

TLibs 2.1.0 and RPCharacters 2.1.0 are published with verified release artifacts. No server deployment has been performed.

Summary by CodeRabbit

• Gameplay
  • Experiments now spend RPCharacters focus points instead of TFMCCore mental points. The configurable attribute that lowers reveal and confirmation thresholds remains unchanged, so existing threshold adjustments continue to work as before.
• Compatibility
  • RPCharacters is now required for the plugin’s focus-point functionality. Other plugin requirements are unchanged.

📝 Walkthrough

Walkthrough

The project replaces its TFMCCore dependency with RPCharacters. PlayerManager now gets the focus service through RPCharacters, while retaining its existing unavailable-service behavior.

Changes

Focus Service Migration

Layer / File(s)	Summary
Declare RPCharacters dependency pom.xml, src/main/resources/plugin.yml	The Maven dependency and plugin hard dependency change from TFMCCore to RPCharacters. The Maven version is now 2.1.0.
Use RPCharacters focus service src/main/java/net/tfminecraft/research/manager/PlayerManager.java, README.md	PlayerManager gets the focus service from RPCharacters. Existing null fallbacks and grant behavior remain unchanged. The README now says experiments spend RPCharacters focus points.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 4a221

Clean builds remain blocked until RPCharacters 2.1.0 is published and pinned-release CI can resolve it. Confirm that dependency before merging.

RPCharacters joins the trail.

Old fallbacks still prevail.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Publish the pinned dependency before merge.

Pinned-release CI cannot resolve net.tfminecraft:rpcharacters:2.1.0 while it remains unpublished. This blocks clean builds that resolve the declared dependency. A source-built candidate does not validate this Maven coordinate. Keep this change gated until the provider publishes 2.1.0 and pinned-release CI resolves it. RPCharacters #27 remains open and reports that no provider release has occurred as of September 24, 2026. (github.com)
