docs(plugin): basecoat + hotwire CLAUDE.md inaccurately claim view-scope mixin injection

[bpamiri]

Follow-up from #2247 / #2256.

Background

Both package CLAUDE.md files claim the package loader injects methods into the view scope directly:

• packages/basecoat/CLAUDE.md: "Wheels injects every public method into controller and view scopes via PackageLoader."
• packages/hotwire/CLAUDE.md: "the main CFC (Hotwire.cfc) contains init() and all public methods, which Wheels injects into controller and view scopes via PackageLoader."

Neither statement is accurate — view is not in variables.mixableComponents, and #2247 now rejects it with a clear error. Helpers are callable in views, but only because Wheels views execute in the controller's variables scope, so controller mixins surface transitively.

Fix

• Update packages/basecoat/CLAUDE.md to state controller mixins surface in views via the controller scope.
• Update packages/hotwire/CLAUDE.md with the same correction.
• Spot-check packages/basecoat/.ai/ARCHITECTURE.md and packages/hotwire/.ai/ARCHITECTURE.md for the same inaccuracy.
• Make sure the user-facing READMEs still match observed behavior (they already use "via the package mixin system" which is accurate).

Acceptance

• No package-internal doc claims there is a view mixin target.
• The explanation of how helpers become available in views describes the controller-scope inheritance, not a direct view mixin.

Out of scope

No code changes — documentation only.

Fixed via cross-repo PRs (the packages/ directory moved out in #2266):

• docs: clarify controller-scope mixin inheritance in views wheels-basecoat#1 — CLAUDE.md + README.md (README line 99 had the same inaccuracy)
• docs: clarify controller-scope mixin inheritance in views wheels-hotwire#1 — CLAUDE.md

Spot-checked both .ai/ARCHITECTURE.md files — neither had the "view scope injection" claim. Will close this once both PRs merge.
