[Feature Request] Add option to skip trust prompt when .claude/settings.local.json allows it

Bug Description
Feature request: Option to skip trust prompt when settings.local.json exists

Use case: I use git worktrees extensively, with a shared settings.local.json symlinked across all worktrees. Each
worktree is a different absolute path, so I get the "Do you trust the files in this folder?" prompt every time I open
Claude in a new worktree - even though I've already explicitly configured my permissions in settings.local.json.

The problem: The existence of a .claude/settings.local.json file with permissions.allow entries is itself an explicit
declaration of trust. Prompting me to confirm trust for a directory where I've already placed a carefully crafted
settings file is redundant. I wrote the file - I obviously trust it.

Proposed solution: Add a setting (in ~/.claude/settings.json or CLI flag) like:

{
"trustProjectsWithLocalSettings": true
}

Or a CLI flag: --trust-local-settings

When enabled, if .claude/settings.local.json exists in the project, skip the trust prompt entirely. The settings file IS
the trust declaration.

Current workaround: Manually accepting the prompt in every new worktree, which defeats the purpose of having shared,
pre-configured settings.
