Conversation
Previously, autocompletion only worked within log stream selectors. LogQL supports additional pipeline expressions after the stream selector, including line filters (|=, !=, |~, !~) and parser functions (json, logfmt, pattern, regexp, unpack, unwrap). This commit adds context-aware completions for: - Line filter operators after stream selectors - Parser and formatting functions The completion detection is split into detectLabelCompletion() and detectPipeCompletion(). ERROR_NODE cases are handled to provide completions even when syntax is incomplete or malformed. Signed-off-by: Jeremy Rickards <jeremy.rickards@sap.com>

Description
This is a follow-up PR to #496. That PR added autocompletion, but mistakenly only for log stream selectors.
This PR extends autocompletion to support more LogQL:
|=,!=,|~,!~) after stream selectorsjson,logfmt,pattern,regexp,unpack,unwrap)This PR also contains some refactoring to separate label completion and pipe completion into their own functions and helpers. Finally, the PR also adds tests for the completion.
The testing instructions are the same as in #496.
