chore: adapt CLAUDE.md to Opus 5 with /doctor

[diegolmello]

Proposed changes

CLAUDE.md is loaded into context at the start of every Claude Code session in this repo. Most of its 101 lines restated facts a session can read directly from the repo, so they cost context on every run without adding information — and one line was factually wrong.

Removed:

• Stack and version bullets (React, React Native, Expo, TypeScript config, Node engines) — already in package.json and tsconfig.json, and they go stale silently.
• The commands block, apart from corepack enable and the pod-install ordering note — every other entry is a standard package.json script.
• Prettier and ESLint config restatement — already in .prettierrc.js and .eslintrc.js.
• The Architecture section. The Redux / WatermelonDB / React Navigation bullets are all in package.json and the directory names match the concepts one-to-one. The app/ee/ Enterprise line and the "VoIP and VideoConf are separate features" warning are both covered better by CONTEXT.md, which is a ubiquitous-language glossary. What survives is two gotchas that nothing else states: the local-first data flow, and the fact that Redux and Zustand coexist so global state is not all in one place.
• The Entry Points section.
• The claim that pre-commit hooks enforce lint and tests. There is no .husky directory and no pre-commit config in the repo; CI is the only gate. Replaced with an accurate note.

Kept everything not derivable from the codebase: the CONTEXT.md pointer, platform floors, corepack enable, pod-install before iOS builds, the before-committing directive, the offline-first data-flow rationale, the note that VideoConf may be removed, and the warning that VoIP and VideoConf are separate features.

101 lines down to 31, roughly 830 fewer tokens of context per session.

How to test or reproduce

Read CLAUDE.md and confirm nothing removed is unavailable from the repo itself, and that nothing non-derivable was lost. Documentation only — no source code, build config, or test touched.

Further comments

Lint and unit tests were not run: this PR changes one Markdown file and touches no source, build config, or test.

The removed content is recoverable from this PR's diff if any of it turns out to be worth keeping. The Pre-commit hooks enforce these checks line was verified false: no .husky directory, no pre-commit config, and package.json has no prepare hook wiring one up.

Summary by CodeRabbit

• Documentation
  • Simplified project guidance for a more focused development experience.
  • Reduced setup, testing, linting, and formatting instructions to essential commands.

Walkthrough

CLAUDE.md was shortened to retain project context, essential setup and validation commands, and concise notes about local-first synchronization and mixed state management.

Changes

CLAUDE.md guidance

Layer / File(s)	Summary
Commands and code style guidance CLAUDE.md	Project overview, setup instructions, and pre-commit commands are reduced to essential guidance, with other commands delegated to package.json scripts.
Architecture overview CLAUDE.md	Detailed architecture documentation is replaced with notes describing WatermelonDB and saga synchronization, plus Redux global/server state and feature-local Zustand stores.

- Line 22: Update the “Before committing” guidance in CLAUDE.md to state that
pnpm prettier-lint formats the entire repository and may rewrite unrelated
files, while TZ=UTC pnpm test runs the full Jest suite. Remove the implication
that either command is limited to modified files, and retain the note that CI is
