[JinwooHwang]

Summary

Updates the SLF4J API version and copyright attribution in the assembled distribution LICENSE file:

• Previous: SLF4J API v1.7.32, Copyright (c) 2004–2017 QOS.ch
• Updated: SLF4J API v1.7.36, Copyright (c) 2004–2025 QOS.ch

Rationale

• Reflects the actual SLF4J version now bundled and aligns copyright years with upstream project notice.
• Ensures compliance and accuracy of third‑party attributions.

Scope

• Documentation/license metadata only.
• No functional or dependency changes introduced in this PR (dependency was already at 1.7.36, license text lagged behind).

Validation

• Confirmed build includes slf4j-api 1.7.36.
• Verified upstream LICENSE/COPYRIGHT years (2025 appears in current SLF4J distribution).

Impact

• None to runtime, packaging only. Improves legal clarity.

Checklist

• LICENSE updated
• Matches currently resolved dependency version
• No other attributions modified
