docs: fix grpc endpoint examples

[compoodment]

Summary

• Replaces two invalid TLS configuration examples that used tcp:yourvector service.internal:50051.
• Uses tcp:libravdb.internal:50051, which matches the documented tcp:<host>:<port> endpoint shape.

Motivation

The old placeholder included a space in the host name. That contradicts the endpoint format documented elsewhere and becomes especially confusing now that HTTP-style and unsupported endpoint schemes fail fast.

Verification

• grep -RIn "yourvector service" docs README.md openclaw.plugin.json src test || true — no remaining matches
• git diff --check — pass

Docs-only change; no runtime tests run.

Documentation Fix: gRPC Endpoint Examples

This pull request corrects invalid placeholder values in gRPC TLS configuration examples in docs/configuration.md.

Changes

Two JSON configuration examples in the "Remote vector service with CA-issued cert" and "Remote vector service with mTLS" sections have been updated:

• Changed grpcEndpoint placeholder from tcp:yourvector service.internal:50051 to tcp:libravdb.internal:50051

Rationale

The previous placeholder contained a space in the hostname (yourvector service), which contradicts the documented tcp:<host>:<port> endpoint format and could cause confusion given that HTTP-style and unsupported endpoint schemes now fail fast with validation.

Impact

• Documentation-only change — no code modifications, no runtime behavior changes
• Lines changed: +2/-2
• Complexity: No Big O notation or cyclomatic complexity implications (documentation only)

📝 A rabbit hops through docs with care,
Two examples now match, fair and square,
From "yourvector" to "libravdb" so bright,
The configuration examples gleam just right! ✨

Vale Review

Verdict: no actionable findings.

This is a docs-only correction in docs/configuration.md: both TLS examples now use tcp:libravdb.internal:50051 instead of the invalid placeholder containing a space. That matches the documented tcp:<host>:<port> endpoint shape and avoids teaching users a malformed gRPC endpoint.

Verification:

gh pr diff 345 --repo xDarkicex/openclaw-memory-libravdb
gh pr checks 345 --repo xDarkicex/openclaw-memory-libravdb

CodeRabbit is passing. I did not run runtime tests because the PR changes documentation examples only.

Vale Review

Quality: Q2/5 — smoke
Name: Docs: fix gRPC endpoint examples

Evidence: Two placeholder hostnames in docs/configuration.md changed from tcp:yourvector service.internal:50051 (space in hostname — invalid per the tcp:<host>:<port> format) to tcp:libravdb.internal:50051.

Assessment: Correct and narrow docs fix. The old placeholder was invalid and confusing, especially after PR #343 added endpoint scheme validation. No behavioral change.

Why Q2: Docs-only fix with no runtime impact. Useful but not action-worthy beyond a quick approve. Already correct.
