🧾 docs: Document v0.8.6 Env, Config, And Changelog

[danny-avila]

Summary

I refreshed the v0.8.6 docs updates against current docs main and regenerated the release changelog from the latest generated release notes.

• Added dotenv coverage for admin-panel redirect URLs, file logging control, OpenTelemetry tracing, session cookie secure overrides, and MCP streamable HTTP response limits.
• Documented new librechat.yaml fields for retention mode, per-server MCP proxy URLs, and model-spec badge row hiding.
• Updated the retention docs to clarify that retentionMode: "all" includes persistent agent resource files.
• Added the config_v1.3.12 changelog entry and bumped example config versions to 1.3.12.
• Refreshed the v0.8.6 release changelog from the formatted temp-changelog.md; it now covers 127 changes and 17 new contributors since v0.8.6-rc1.
• Updated admin panel, logging, Redis, and MCP reference pages with the related setup notes.
• Left detailed HyperDX RUM docs to docs: add HyperDX RUM configuration guide #585 and Bedrock profile/API-key auth coverage to 🪪 docs: Document Bedrock AWS Profile Credentials #584 to avoid duplicate docs.

Change Type

• Documentation update

Testing

Test Configuration:

• Ran npm exec -- prettier --check temp-changelog.md in /Users/danny/Projects/LibreChat.
• Ran pnpm exec prettier --check on the changelog/config docs files that are Prettier-clean on main.
• Ran git diff --check.
• Checked merge-tree compatibility with overlapping docs PRs Revise credentials section for Kubernetes Secret #590, docs: clarify requiresOAuth applies to all remote MCP transports, not just sse #589, docs: document interface.marketplace.categories #587, docs: add HyperDX RUM configuration guide #585, 🪪 docs: Document Bedrock AWS Profile Credentials #584, docs(balance): document auto-refill behavior and account-menu indicator #583, Update dotenv.mdx #582, docs: add Tuning Engines endpoint example #581, Updated Documentation on Docker image removal commands #580, docs: fix Docker image cleanup command #578, Fix LibreChat Docker image removal command #576, docs: document configurable Cohere reranker API URL #571, docs: add branding config and disableProviderUpload per-endpoint field #557, and docs: MCP SSE custom server guide — express.json() pitfall and autoApprove troubleshooting #526.
