fix(find): accept native find flags (-name, -type, etc.)

[sahilmgandhi]

Summary

• rtk find . -name "*.rs" -type f fails with unexpected argument '-n' found because Clap decomposes -name into short flags (-n, -a, -m, -e) and -n is not defined
• Changed Find to use trailing_var_arg = true, allow_hyphen_values = true (consistent with Grep, Ls, Tree, and most other RTK commands)
• Added parse_find_args() that detects and handles both native find syntax (-name, -type, -maxdepth, -iname) and existing RTK syntax (rtk find *.rs src -m 50 -t f)
• Rejects unsupported compound predicates (-not, -exec, -delete, etc.) with a clear error instead of silently giving wrong results

Changes

File	Change
src/main.rs	Replaced named Find args with trailing_var_arg + dispatch to run_from_args()
src/find_cmd.rs	Added parse_find_args() with native/RTK syntax detection, FindArgs with Default, next_arg helper. Fixed -maxdepth to wire to WalkBuilder::max_depth (traversal depth, not display limit). -iname now performs case-insensitive glob matching. Unsupported flags (-not, -exec, etc.) bail with clear error. 15 new tests.

Test plan

• cargo fmt --all passes
• cargo clippy --all-targets clean
• cargo test find_cmd — 27/27 tests pass (15 new)
• cargo test --all — 409/409 tests pass
• Manual test: rtk find . -name "*.rs" -type f — works, returns compact output

Nice work! Clean approach, consistent with how we handle git.rs and grep_cmd.rs (trailing_var_arg + manual parsing). Auto-detection of native vs RTK syntax is smart.

15 new tests, security is fine (-exec properly rejected), -iname and -maxdepth are good additions.

One thing to fix before merge:

In parse_native_find_args(), unknown flags are silently swallowed by the _ => {} catch-all. This means rtk find . -mindepth 2 -name "*.rs" succeeds but ignores -mindepth — the user thinks it works but gets wrong results.

Please add a warning on stderr for unknown flags:

_ => {
    eprintln!("rtk find: unknown flag '{}', ignored", args[i]);
}

This way users know their flag was dropped instead of getting silently wrong results.

Everything else looks good — small fix and we can merge 👍

Thanks for this PR! Clean approach, consistent with how we handle git.rs and grep_cmd.rs (trailing_var_arg + manual parsing). Auto-detection of native vs RTK syntax is smart.

Tests are solid (15 new), security is fine (-exec properly rejected), and -iname / -maxdepth are nice additions.

One thing to fix before merge: in parse_native_find_args(), unknown flags are silently swallowed by the _ => {} catch-all. I tested with -mindepth and it succeeds without warning — the
user thinks it works but gets wrong results.

_ => {
eprintln!("rtk find: unknown flag '{}', ignored", args[i]);
}

Small fix and we can merge — thanks again!

Thank you for the review @pszymkowiak, I took a pass at it, and updated the PR accordingly.
