Lab #1173: swamp workflow history search OOMs on workflows with large run history

Description

'swamp workflow history search ' crashes the CLI with a fatal JavaScript out-of-memory error instead of returning results, when the target workflow has a large number of accumulated run records.

Steps to reproduce

Have a workflow with several thousand recorded runs under .swamp/workflow-runs// (in our case: 3166 runs, ~9.8G total, from a workflow that ran every 2 minutes for weeks).
Run: swamp workflow history search k8s-health-sweep --json
CLI logs repeated "Incremental Mark-Compact" GC messages, then crashes: "Fatal JavaScript out of memory: Ineffective mark-compacts near heap limit" with a V8 C stack trace.

Environment

swamp 20260714.215032.0-sha.c8bdff3c
Linux (WSL2), repo with .swamp/workflow-runs// containing 3166 run YAML+log file pairs for the affected workflow.

Impact

Any workflow that accumulates a few thousand historical runs (easy to hit with a sub-5-minute schedule and no retention, see companion feature request about missing workflow-runs/outputs retention) becomes permanently unqueryable via 'workflow history search' — the command always OOMs. The only way to inspect or diagnose such a workflow's history is to read the raw YAML files directly, which defeats the point of the CLI.

Move the Zod argument-field extractor into @swamp-club/extension-scoring so the CLI and registry read schemas alike

Datastore rework Phase 5 (team mode) 2/3: the CLI's serve upstream — with serverAddress, a v3 checkout commits, reads chunks and catches up through serve's datastore API, with no storage credentials

Extension dependencies: the shared import scan reads Babel syntax, not tokens (follow-up to #3969)

Manual: the supported extension dependency categories, the canonical form and the lock rule, rewritten once against the final design

Registry audits v2 extension archives as written, and a range costs the loose point only without a valid lock

Extension consumers keep the publisher's bundle: pull, update and auto-resolve stop rebuilding (direction A for #3634)

Extension push: inputs that open up (workspace root lock, ancestor config refused by name, JSR dist-tags) and the skill docs rewritten once

Extension push ships the canonical form: every npm:/jsr: import pinned exact, and a v2 dependency-audit.json

A long-lived serve client for extensions, and a stable rate_limited error code

swamp serve on a v3 datastore never settles a workflow run left running by a stopped instance: boot reaper skips it as belonging to a remote instance

swamp serve on a v3 datastore: a run interrupted at a clean shutdown is never committed when the bucket is slow, and stays running for every other checkout

Support creating 1Password vaults for new clients

Filesystem datastore: an unclean shutdown leaves zero-byte data versions as the latest version, and `doctor datastores --repair` does not detect them

datastore_v3_replica_verify_test stall case flakes under the full integration run: restore.pid is read before the stub writes it

Generated state schemas require every child of nested objects, so normal resources warn on create/get

Annotate and retain past workflow runs and data after the fact

A workflow step's method output is invisible to `data query` and `data list`, and the method summary's retrieval command returns an older run's data

Skill propulsion rule is silent when no transition is satisfied because stage work is outstanding

package.json mode: no loose-specifier warning for a range push ships as the exact installed version

extension fmt (and any command) creates or rewrites deno.lock when the extension lives in the repo's loaded extensions/ dir

serve shutdown does not wait for worker status writes, and its listener accepts workers after the gateway is disposed
