🚀 docs: Prepare v0.8.8 Stable Release

[lia-by-librechat]

Summary

Prepare the v0.8.8 stable changelog from the cumulative rc3 notes, the merged rc4 docs PR #777, and the changes merged after rc4. The entry covers each of the 1,221 LibreChat PRs merged between v0.8.7 and dev at 4d33d8c2c71ad497fdfaa2c4334b0a2293bcbd67, plus four direct commits, with 37 first-time contributors. A closed, unmerged rc3 release draft incorrectly listed by the old changelog is not repeated.

Documentation updates

• Extend Config v1.3.17 notes with workspace transitions, request and shutdown budgets, idle recovery caps, Agent selector limits, credential validation, config overrides, and rate-limit fixes. The config version remains 1.3.17.
• Explain saved-chat workspace recovery and opt-in attach/detach, the Code API rollout prerequisite for longer queue admission, and where uploads actually live in attached workspaces.
• Document background task cards and header controls, plus fail-closed tool-approval behavior for headless Agents API calls.
• Correct attached-workspace timeout paths to configSchema.limits, explain linked-worktree lanes, command-admission reserves, tool preparation versus call timing, and MCP OAuth redirect restrictions.

The v0.8.8 tag is not published yet. These notes are prepared against the pinned dev head above, not the separate canary branch; recheck merged PR coverage, release date, and the compare link when the stable tag is cut. The older v0.8.8 draft #763 predates rc4, so this is a separate PR from current main rather than a merge of its stale branch.

Validation

• MDX formatting with Prettier and git diff --check
• Changelog coverage audit against v0.8.7..origin/dev and schema/default checks against the same head
• Docs CI will run the full Fumadocs typecheck, lint, unit tests, and e2e build

Review head: b4e43be7dd0f7db3c91eb5818713d0360a6979e3. This commit adds the cumulative v0.8.8 changelog through LibreChat dev 42568a0077bcd13ce00f95261eb34d811db41673 and updates the v1.3.17 operator, attached-workspace, background-task, and Agents API docs. Please review this exact head, particularly the release coverage and opt-in rollout caveats.

Review head: 3c9bde1faa7d264cf98ac3172bedacb5ae802963. The cumulative v0.8.8 notes and operator guidance are unchanged; this head clarifies that headless tool approval applies to LibreChat-executed tools, while caller-executed functions remain the API caller's responsibility. Targeted MDX formatting and the merged-PR coverage audit pass.

Review head: d56080fc74e3716bee2aaa1c997c99338fa309aa. The stable v0.8.8 notes now cover all 1,221 merged PRs plus four direct commits through LibreChat release branch 4d33d8c2c71ad497fdfaa2c4334b0a2293bcbd67. This head also corrects the attached-workspace YAML field paths and documents linked-worktree rollout, command admission budgeting, Agent tool timing, and MCP OAuth redirect policy. Canary-only work is intentionally excluded. Please review this exact head for operator accuracy and release scope.

Review head: 35854d30aba66bdbbe5959625b8bd2d3fdb3c022. Same complete v0.8.8 audit through LibreChat 4d33d8c2c71ad497fdfaa2c4334b0a2293bcbd67; this follow-up makes the linked-worktree examples exact: file tools route by their target path and Bash routes by its cwd, not by a cd inside a command. Please review this head.
