Add Claude Code project settings (.claude/settings.json)

[yepzdk]

Add a committed .claude/settings.json so the whole team shares the same Claude Code harness configuration for this repo.

Scope

• Create .claude/settings.json (committed, team-shared).
• Configure a sensible permission allowlist for common project commands (e.g. Taskfile tasks, composer, docker compose, git read-only, coding-standards checks) to reduce permission prompts.
• Add any project hooks if useful (e.g. run coding standards / lint on stop).
• Document any local-only overrides via .claude/settings.local.json (gitignored).
• Add .claude/settings.local.json to .gitignore.

Acceptance criteria

• .claude/settings.json committed with a documented permission allowlist.
• .claude/settings.local.json gitignored.
• Reviewed and merged via PR.

Part of the Base setup milestone. Related to the CLAUDE.md issue.
