feat(query-coordinator): Add crate scaffolding; Add query job submitter interface.

[Bill-hbrhbr]

Description

This PR introduces the initial query-coordinator crate and its first coordinator-facing interface.

This PR:

• Registers query-coordinator as a Rust workspace member.
• Defines the QueryJobSubmitter trait and its query submission inputs.
• Adds a SpiderClient implementation skeleton, leaving task-graph construction as todo!().
• Adds the shared ArchiveId and QueryJobId aliases to clp-rust-utils.

This PR depends on #2503, which introduces the shared query task I/O contract, including ClpSQueryOption, used by the QueryJobSubmitter interface.

Checklist

• The PR satisfies the contribution guidelines.
• This is a breaking change and that has been indicated in the PR title, OR this isn't a
  breaking change.
• Necessary docs have been updated, OR no docs need to be updated.

Validation performed

• No unit tests were added because this PR only defines the crate and submitter interface.
• task lint:fix-rust passes.
• The affected crates' existing unit, integration, and relevant documentation tests pass.

Summary by CodeRabbit

• New Features

  • Added foundational support for coordinating query jobs across archives and datasets.
  • Added configurable query options, including query text, time ranges, result limits, and case sensitivity.
  • Added support for registering clp-s search tasks with the task executor.

• Limitations

  • Query execution and job submission are intentionally deferred behind uninhabited inputs and todo!() staging seams.

Walkthrough

The workspace adds query protocol types, registers a CLP-S query task with Spider, and introduces a query-coordinator crate with an asynchronous submission interface. The task and SpiderClient implementation remain unimplemented.

Changes

Query job scaffolding

Layer / File(s)	Summary
Query data contracts components/clp-rust-utils/src/job_config/search.rs, components/clp-rust-utils/src/task_io.rs, components/clp-rust-utils/src/task_io/query.rs	Adds ArchiveId, QueryJobId, ClpSQueryOption, and OutputHandle. Exposes the task_io::query module.
Spider query task registration components/clp-tdl-package/src/task/mod.rs, components/clp-tdl-package/src/task/query/mod.rs, components/clp-tdl-package/src/lib.rs	Adds and registers query::clp_s_search_task. The task accepts query inputs and currently calls todo!().
Query coordinator submission interface Cargo.toml, components/query-coordinator/Cargo.toml, components/query-coordinator/src/*	Adds the workspace crate, public Error type, ArchiveMetadata, QueryJobSubmitter trait, and SpiderClient implementation. The implementation currently calls todo!().

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e0566

The PR adds a new query-submission contract, but its current implementation can panic when called and the required output-handle type cannot produce valid task payloads, leaving submission unusable and potentially crashing an integrating caller. Merge should wait for these issues to be fixed or explicitly accepted, with authorization ownership defined before implementation.

In `@components/clp-rust-utils/src/task_io/query.rs`:
- Line 31: Update OutputHandle so it has at least one constructible variant that
Spider can deserialize for the clp_s_search_task contract, or remove the
parameter until a valid output-handle contract is defined. Add a deserialization
test covering one valid payload.

In `@components/query-coordinator/src/query_job_submitter/spider.rs`:
- Line 35: Replace the todo! panic in SpiderClient::submit_query_job with an
explicit unsupported-operation error returned as Err, preserving the declared
Result<JobId, Error> contract until CLP-S task-graph submission is implemented.

Apply the same fix in `@components/clp-tdl-package/src/task/query/mod.rs` at line
19: The registered query task is the second instance of the same unimplemented
panic behavior.

[LinZhihao-723]

In Rust's standard documentation conventions, people usually do not add a # Panics section for a temporary todo! macro. Is this added by u or codex?

[Bill-hbrhbr]

codex. but anyway I wasn't clear what to do with todo. update my agents to follow this rule in the future

[LinZhihao-723]

We usually document # Panics section for fatal errors like expect and assert. This is only enforced for public APIs, as the linter will complain when it is omitted. Otherwise, it's optional to document the fatal cases (for example, you don't need to document this in a test case that uses assert to panic on a failed assertion).

[LinZhihao-723]

For the PR title, how about:

feat(query-coordinator): Add crate scaffolding; Add query job submitter interface.

"Initialize crate" sounds a bit weird.

Please merge this PR after #2503.
