Filter stub commands from resume-safe help

Keep claw --help's resume-safe slash command summary aligned with the interactive command list by filtering STUB_COMMANDS and adding regression coverage.

    **Source.** Jobdori dogfood 2026-04-18 against `/tmp/cdJ` on main HEAD `b7539e6` in response to Clawhip pinpoint nudge at `1494744278423961742`. Adjacent to #85 (skill discovery ancestor walk) on the *discovery* side — #85 is "skills are discovered too broadly," #95 is "skills are *installed* too broadly." Together they bound the skill-surface trust problem from both the read and the write axes. Distinct sub-cluster from the permission-audit bundle (#50 / #87 / #91 / #94) and from the truth-audit cluster (#80–#87, #89): this is specifically about *scope asymmetry between install and settings* and the *missing uninstall verb*.

The `render_help` output emits two separate enumerations of slash commands; only one of them applies the stub filter. The Resume-safe summary advertises `/budget`, `/rate-limit`, `/metrics`, `/diagnostics`, `/bookmarks`, `/workspace`, `/reasoning`, `/changelog`, `/vim`, `/summary`, `/brief`, `/advisor`, `/stickers`, `/insights`, `/thinkback`, `/keybindings`, `/privacy-settings`, `/output-style`, `/allowed-tools`, `/tool-details`, `/language`, `/max-tokens`, `/temperature`, `/system-prompt` — all of which are explicitly in `STUB_COMMANDS` with "Did you mean" guards and no parse arm.

Added `stub_commands_absent_from_resume_safe_help` to lock the filtered one-liner contract alongside the existing REPL completion filter. Fresh proof: `cargo fmt --all --check`, `cargo test -p rusty-claude-cli stub_commands_absent_from_resume_safe_help -- --nocapture`, and `cargo test -p rusty-claude-cli parses_direct_cli_actions -- --nocapture` pass.

+Iteration 2026-04-29 - ROADMAP #96 COMPLETED
+------------------------------------------------
+- Pulled origin/main: already up to date.
+- Selected ROADMAP #96 as a small repo-local Immediate Backlog item: the `claw --help` Resume-safe command summary leaked slash-command stubs despite the main Interactive command listing filtering them.
+- Files: rust/crates/rusty-claude-cli/src/main.rs, ROADMAP.md, progress.txt.
+- Changed help rendering to filter `resume_supported_slash_commands()` through `STUB_COMMANDS` before building the Resume-safe one-liner.
+- Added `stub_commands_absent_from_resume_safe_help` regression coverage so future stub additions cannot leak into the Resume-safe summary.
+- Targeted verification: `cargo test -p rusty-claude-cli stub_commands_absent_from_resume_safe_help -- --nocapture` passed; `cargo test -p rusty-claude-cli parses_direct_cli_actions -- --nocapture` passed.
+- Format/check verification: `cargo fmt --all --check`, `git diff --check`, and `cargo check -p rusty-claude-cli` passed.
+- Broader clippy note: `cargo clippy -p rusty-claude-cli --all-targets -- -D warnings` is blocked by pre-existing `clippy::unnecessary_wraps` failures in `rust/crates/commands/src/lib.rs` (`render_mcp_report_for`, `render_mcp_report_json_for`), outside this diff.
