feat(arg-parsing): accept comma-separated project slugs

[betegon]

Summary

sentry issue list acme/web,api currently requests the concatenated slug and 404s. This lets issue list and project list accept a comma-separated project selector after the org (<org>/a,b). Parsing is enabled per command via parseOrgProjectArg(target, { allowProjectList: true }); every other command keeps today's semantics, including comma-containing project names in project create.

issue list <org>/a,b resolves the selector in one call against the org project catalog (findProjectsInOrg), fails with a ResolutionError if any slug is unknown (the API would otherwise silently drop it), and then issues a single SDK request with the resolved IDs through the repeated project query parameter. Sorting, --limit, and cursor pagination stay server-side and share the org-all code path. The filter can never widen to the whole org: a project whose ID is not numeric falls back to its slug.

project list <org>/a,b fetches the catalog once and selects locally, reporting slugs that do not exist separately from slugs excluded by --platform. Catalog errors propagate like org-all instead of rendering as "no projects found".

A plain <org>/<project> target is unchanged in both commands (same handlers, hints, and cursor behaviour as main).

Implementation notes

• listIssuesPaginated/listIssuesAllPages take projects?: ReadonlyArray<number | string> instead of a single projectId; existing callers pass [id].
• findProjectsInOrg(org, slugs) in resolve-target.ts is the shared catalog lookup for both commands.
• formatProjectTarget and explicitProjectSlugs in arg-parsing.ts keep titles, hints, and cursor context keys formatted identically.

Test plan

• sentry issue list <org>/web,api --json resolves the catalog once and sends one SDK request with both project IDs
• sentry issue list <org>/web,nope fails with a resolution error before querying issues
• comma selectors trim empty entries, de-duplicate, reject display names, and validate each slug
• <org>/a,b targets render the multi-project footer tip and -c next/prev hints with the full selector
• sentry project list <org>/web,api uses one catalog request and preserves input order
• project listing distinguishes missing projects from --platform filtering
• single-project issue list / project list targets and comma-containing project create names behave as before
