Update dependencies to latest minor/patch versions

[Copilot]

Updated all dependencies to their latest compatible minor and patch versions within semver constraints.

Changes

Dependency bumps:

• env_logger: 0.9 → 0.11
• dialoguer: 0.10.4 → 0.11
• handlebars: 4.3 → 4.5
• syntect: 5.0 → 5.3
• regex: 1.8.1 → 1.10
• built: 0.5 → 0.6
• ureq: 2.5 → 2.10

Breaking changes:

1. env_logger 0.11 - Styling API removed, replaced with ANSI escape codes:

// Before: buf.style().set_color(Color::Yellow)
// After: direct ANSI codes
writeln!(buf, "\x1b[33m{}: {}\x1b[0m", record.level(), record.args())

2. dialoguer 0.11 - Input instances no longer reusable, now created per interaction:

// Before: reused mut input in loop
// After: fresh instance per prompt
let value: String = if use_colors {
    dialoguer::Input::with_theme(&theme)
        .with_prompt(key.clone())
        .interact_text()
        .unwrap()
} else { /* ... */ };

3. httpx - Added edition = "2021" to suppress compiler warning

Ran cargo update to pull latest transitive dependencies (78 packages updated).

Original prompt
