Interactive config wizard (teeclip --configure)

[djdarcy]

Summary

Add a teeclip --configure command that interactively walks users through creating or editing ~/.teeclip/config.toml. Similar to git config --global or aws configure.

Motivation

Currently:

• teeclip --config shows the effective configuration (read-only)
• Changing settings requires hand-editing ~/.teeclip/config.toml

For settings like encryption where multiple values need to coordinate (encryption, auth_method, salt setup), a guided wizard would provide a much better onboarding experience.

Proposed UX

$ teeclip --configure

teeclip configuration wizard
Config file: ~/.teeclip/config.toml

[history]
  Enable clipboard history? [Y/n]: y
  Maximum entries to keep [50]: 100
  Auto-save piped content? [Y/n]: y

[security]
  Enable encryption? [y/N]: y
  Auth method (os/password) [os]: os

[clipboard]
  Force backend (leave empty for auto-detect) []:

[output]
  Quiet mode (suppress warnings)? [y/N]: n

Config saved to ~/.teeclip/config.toml

Design Notes

• Should show current values as defaults (in brackets) when editing an existing config
• Creating a new config uses the built-in defaults
• Encryption setup (--configure with encryption=yes) could handle salt generation and initial password setup in one flow
• Non-interactive mode: teeclip --configure --set history.max_entries=200 for scriptable changes (stretch)

Acceptance Criteria

• teeclip --configure creates or edits config.toml interactively
• Shows current values as defaults when config exists
• Handles encryption setup flow (auth method selection, salt generation)
• --config (read) and --configure (write) form a coherent pair
