auto: save WIP progress from rcc session

The Rust CLI previously hid init behind the REPL slash-command surface and only
created a starter CLAUDE.md. This change adds a direct `init` subcommand and
moves bootstrap behavior into a shared helper so `/init` and `init` create the
same project scaffolding: `.claude/`, `.claude.json`, starter `CLAUDE.md`, and
local-only `.gitignore` entries. The generated guidance now adapts to a small,
explicit set of repository markers so new projects get language/framework-aware
starting instructions without overwriting existing files.

Constraint: Runtime config precedence already treats `.claude.json`, `.claude/settings.json`, and `.claude/settings.local.json` as separate scopes
Constraint: `.claude/sessions/` is used for local session persistence and should not be committed by default
Rejected: Keep init as REPL-only `/init` behavior | would not satisfy the requested direct init command and keeps bootstrap discoverability low
Rejected: Ignore all of `.claude/` | would hide shared project config that the runtime can intentionally load
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep direct `init` and `/init` on the same helper path and keep detection heuristics bounded to explicit repository markers
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: interactive manual run of `rusty-claude-cli init` against a non-test repository
