Enable Claude Code permissions in global mode and update docs/tests

[dyoshikawa]

Motivation

• Allow Rulesync to generate/import permissions for Claude Code in global mode so users can manage ~/.claude/settings.json as well as project-scoped settings.
• Clarify documentation about where generated Claude Code settings are written in project vs global mode.

Description

• Mark claudecode as supportsGlobal: true in the PermissionsProcessor factory so the processor includes Claude Code in global targets.
• Update unit tests and generation/import logic expectations to include claudecode for global mode (generate/import tests and PermissionsProcessor target tests).
• Add an e2e test should generate claudecode permissions in home directory with --global to validate writing permissions to the home .claude/settings.json and preserving existing fields.
• Update documentation and README entries (README.md, docs/reference/*, skills/rulesync/*, and supported-tools tables) to reflect that Claude Code supports global-mode permissions and to clarify the location of generated Claude settings.

Testing

• Ran unit tests including permissions-processor.test.ts, generate.test.ts, and import.test.ts, and updated expectations to reflect global support for claudecode, and they passed.
• Ran the end-to-end permissions spec e2e-permissions.spec.ts including the new global-mode claudecode case, and it passed.
• Ran overall test suite to ensure no regressions and all automated tests succeeded.

Pull request overview

Enables Claude Code permissions support in global mode so Rulesync can generate/import permissions against the user-scoped ~/.claude/settings.json, and updates tests/docs to reflect the new capability.

Changes:

• Mark claudecode permissions as supportsGlobal: true so it’s included in global-mode permission targets.
• Update unit tests to expect permissions generation/import to run in global mode when the target supports it.
• Add an E2E test validating global-mode Claude Code permissions generation writes to the home directory and preserves unrelated existing settings; update docs/tables accordingly.
