feat(codegen): cli.stashName so generated CLIs can share one signed-in state

[pyramation]

Summary

Codegen half of the one-store consolidation (constructive-planning#1430). A generated CLI passes its own name as the appstash tool name, so each one gets its own ~/.<cli>/ and its own login. New optional cli.stashName separates where state lives from what the tool is called:

cli: { toolName: 'csdk', stashName: 'constructive' }

-const store = createConfigStore("csdk");
+const store = createConfigStore("csdk", { stashName: "constructive" });

toolName still drives the CSDK_TOKEN / CSDK_API_ENDPOINT env prefixes and the command names in error messages, so sharing a directory doesn't blur the tools' identities. Omitted → byte-identical output to today, so no regeneration is forced on existing consumers.

Threaded through generateExecutorFile, generateMultiTargetExecutorFile and generateHelpersFile as a trailing optional arg (AST, per the codegen rules — createStoreCall() builds the object expression only when a stash name is present).

Also: genomic ^5.6.2 → ^5.6.4. The old genomic pinned inquirerer@4.9.1 transitively, so after #1650 the workspace resolved two copies and pgpm/core failed to build on a private-property mismatch between them (Types have separate declarations of a private property 'rl'). One copy now.

Nothing consumes stashName yet — csdk switching over (and deleting its local config-store.ts duplicate in favor of appstash's) needs stashName in a published appstash, which is dev-utils#105; that lands as a follow-up PR.

Tests: 3 cases in cli-generator.test.ts (absent → plain call, single-target, multi-target executor + helpers). Full codegen suite 364 passing, 123 snapshots unchanged.
