fix(ebay): preserve commerce fields in agent compact output

[freemanconsulting]

Summary\n- keep eBay commerce fields in compact list output so --agent does not strip price/condition/bid data\n- adds regression coverage for listing/sold/auction and comp summary fields\n\n## Why\nThe eBay CLI documents --agent as JSON + compact + non-interactive. For commerce commands like listings/sold/auctions/comp, the generic compact allow-list kept title/url but dropped the fields agents actually need: price, condition, currency, bids, sold_price, etc. Downstream consumers had to avoid --agent to get usable pricing data.\n\n## Test\n- cd library/commerce/ebay && go test ./...\n

Greptile Summary

This PR fixes --agent compact output for eBay commerce commands by extending the compactListFields allow-list with pricing, condition, auction, and statistical fields that agents need to make sense of listings, sold, auctions, and comp output. It also corrects the README to stop advertising saved-search create and feed as working examples.

• helpers.go: Adds 18 eBay-specific fields (price, condition, bids, sold_price, currency, etc.) and 6 comp statistical fields (mean, median, p25, p75, std_dev, sample_size) to the shared compactListFields allow-list; scoped to the eBay CLI only.
• agent-compact-preserves-commerce-fields.json: Adds the required .printing-press-patches/ entry with correctly copied base_run_id and base_printing_press_version from .printing-press.json, satisfying the reprint-guard convention.
• helpers_compact_test.go: New white-box tests verify that commerce and comp fields survive compact mode while verbose fields (description, notes) are stripped.

Confidence Score: 5/5

Safe to merge; the allow-list expansion is additive and scoped to the eBay CLI only, tests cover both new field groups, and the patch file is correctly structured.

All changed code is additive — no existing fields are removed or reordered, and the new fields are eBay-specific enough that false positives in other command outputs are unlikely. The patch file provenance values match .printing-press.json exactly, and the two new tests directly exercise the changed code path. The only gap is the missing contributor attribution, which is a convention miss and does not affect runtime behavior.

.printing-press.json — contributor entry for freemanconsulting (plus README byline and NOTICE) should be added per repo convention before merge.

Important Files Changed

Filename	Overview
library/commerce/ebay/.printing-press-patches/agent-compact-preserves-commerce-fields.json	New patch entry correctly documents the compact allow-list change; base_run_id and base_printing_press_version match .printing-press.json exactly.
library/commerce/ebay/internal/cli/helpers.go	Adds eBay-specific commerce fields and comp statistical fields to the compactListFields allow-list; implementation is correct and scoped to this CLI only.
library/commerce/ebay/internal/cli/helpers_compact_test.go	New white-box tests covering listing/sold/auction field preservation and comp statistical fields; correctly uses package cli to access unexported compactListFields.
library/commerce/ebay/README.md	Correctly replaces not-yet-implemented saved-search/feed examples with --help redirects; straightforward documentation fix.

Missing .printing-press-patches/ entry for this generated-code edit

helpers.go lives inside generated output from the Printing Press; the project's AGENTS.md requires every hand-edit to be recorded under .printing-press-patches/ (a JSON file following the schema used by the three existing entries) so that a future regen carries the intent forward. Without a patch entry, the next printing-press regen will silently overwrite helpers.go and drop this fix, restoring the broken compact output for agents. All three existing patches in that directory (catalog-go-1264-vuln-floor.json, chrome-profile-cookie-selection.json, standalone-pycookiecheat-profile-selection.json) demonstrate the required format.

Context Used: library/commerce/ebay/AGENTS.md (source)
