refactor to use more go-gh

refactor(log): use go-gh pkg/tableprinter for porcelain output

Replace manual tab-separated output with go-gh tableprinter for the
--porcelain flag. The tableprinter automatically adapts to the output:

• TTY mode: Nicely formatted columns with headers, current branch
  marked with '*' prefix, column widths fit to terminal
• Non-TTY mode: Clean TSV output for scripting (unchanged behavior)

This ensures consistent output formatting with other gh CLI commands.

feat(submit): add --web flag to open PRs in browser

Add -w/--web flag to the submit command that opens created or updated
PRs in the default web browser after submission completes.

Uses github.com/cli/go-gh/v2/pkg/browser which respects:

• GH_BROWSER environment variable
• browser setting in gh config
• BROWSER environment variable

The browser package also includes security validation for URLs.

refactor(prompt): use go-gh pkg/prompter for interactive prompts

Replace custom Input, Confirm, and Select implementations with
github.com/cli/go-gh/v2/pkg/prompter (survey-based prompts).

Benefits:

• Arrow key navigation for Select instead of typing numbers
• Type-to-filter in long option lists
• Better handling of terminal edge cases (resizing, interrupts)
• Consistent UX with gh CLI extensions

The survey library is added as a transitive dependency through go-gh.

refactor(prompt): use go-gh pkg/term for terminal detection

Replace github.com/mattn/go-isatty with github.com/cli/go-gh/v2/pkg/term
for terminal detection. This ensures gh-stack respects the same environment
variables as the gh CLI:

• GH_FORCE_TTY: Force TTY mode (useful for CI testing)
• NO_COLOR: Disable color output
• CLICOLOR / CLICOLOR_FORCE: Control color behavior

The direct go-isatty dependency is removed (now transitive via go-gh).
