fix(weave): replace stale version hint in object name validation error message

[rajkumar-prog]

Problem

Fixes #5771

The error message in weave/trace_server/validation.py tells users to upgrade to >0.51.0 to fix invalid object name errors:

Invalid object name: {name}. Contains invalid characters: {invalid_char_set}. Please upgrade your `weave` package to `>0.51.0` to prevent this error.

This is misleading because:

• Weave is already at 0.52+, so users who see this are already on a newer version
• Version-specific hints in error messages always become stale over time

Fix

Replaced the stale version hint with a clear, actionable message that tells users exactly what characters are allowed.

Before:

...Please upgrade your `weave` package to `>0.51.0` to prevent this error.

After:

...Object names must only contain alphanumeric characters, dashes, underscores, and periods.

Hey @rajkumar-prog, thanks for picking this up. One note on the second commit: the sdks/node/weave.openapi.json change isn't mentioned in the PR description (which references #5771 — the validation-message fix). That file is also the input to yarn generate-api for the Node SDK TypeScript bindings, and removing the recursive $ref to LiteralOperation would weaken the generated types. Might be cleaner to split the openapi edit into its own PR.

Closing this in favour of a clean PR that contains only the validation message fix — the openapi.json change accidentally included here belongs to #6871. Reopening with a single-commit branch.
