feat(api): cancel analysis runs from LineageWeave and Naruon compatibility

[seonghobae]

Why

GAP-003A / issue #166 still has no LineageWeave cancel-exchange builder, no Naruon compatibility-listener cancel, and no tepp-loopback TCP proof. ADR 0029 / #361 added POST /v1/analysis-runs/{run_id}/cancel on AnalysisRunLiveService and the Naruon cancel builder only. A published LineageWeave consumer would have to mint a Naruon-labelled cancel. NaruonLiveService still refused every cancel path.

Live slices that this PR does not duplicate:

• feat(analysis): bind validation runs to scientific acceptance evidence #356 analysis_engine scientific-acceptance library
• feat(api): carry scientific acceptance only on terminal results #358 tepp_api terminal-wire DTO
• feat(api): serve scientific acceptance only on loopback status GET #359 GET loopback status
• feat(api): record scientific acceptance via loopback lifecycle POST #360 POST running/terminal lifecycle (stacked on feat(api): serve scientific acceptance only on loopback status GET #359)
• feat(api): cancel accepted and running analysis runs on loopback #361 cancel HTTP on AnalysisRunLiveService (this PR stacks on that head dba3db0e0a43acae929263a06ff3364802f565f3)
• feat(api): drive scientific acceptance via loopback CLI #362 loopback CLI (ADR 0030 on a different stack)
• feat(analysis): bind TDT/CHRONOS composition to an analysis-run profile #364 GAP-007 TDT/CHRONOS analysis-run profile
• feat(api): enumerate analysis runs via loopback collection GET #368 collection GET (parallel on the same feat(api): cancel accepted and running analysis runs on loopback #361 base; different files)
• feat(api): retry failed and cancelled analysis runs on loopback #369 retry
• feat(analysis): execute scientific acceptance on loopback lifecycle #370 loopback engine
• feat(api): enumerate analysis runs via loopback collection CLI #371 collection CLI
• feat(persistence): persist idempotent analysis runs #287 GAP-003B persistence/Compose
• feat(network): replace union-find stand-in with Leiden consensus #351 Leiden

What

Unique GAP-003A consumer-parity cancel slice stacked on #361 over protected main 1bc02f580cf48e1d39da239f0e818453437c31c3:

• lineageweave_analysis_run_cancel_exchange reuses the Naruon cancel builder and replaces only tepp-consumer
• NaruonLiveService serves metric-free cancel for Naruon only; LineageWeave remains refused there
• accepted and running → cancelled (200); already-cancelled is idempotent
• succeeded, failed, unknown, wrong idempotency, and metric keys fail closed
• tepp-loopback create-then-cancel over loopback TCP
• ADR 0030 on the cancel-HTTP lineage (other live PRs may reuse 0030 on unrelated stacks)

Not an ADR 0014 scientific claim. Not GET status. Not lifecycle POST. Not collection GET. Not retry. Not persistence. Does not open NaruonLiveService to LineageWeave.

Closing with replacement mapping to #174. This consumer-parity cancellation stack inherits #361's unauthenticated destructive-operation boundary; swapping tepp-consumer values or proving loopback TCP does not prove caller authorization. Preserve the Naruon/LineageWeave parity and metric-refusal tests as fixtures for the authenticated operations landing vehicle.
