feat(cli): add claw log --since date filter

Replayed the CLI parity changes on top of the latest mainline so the direct command surface now includes a date-filtered git log view alongside the related config, hook, and branch helpers already in flight.

Constraint: The local branch had diverged from origin/main and required a rebase before push
Constraint: Keep the Rust CLI help text, parsing, and focused tests aligned
Rejected: Push the pre-rebase commit directly | non-fast-forward and stale mainline base
Confidence: medium
Scope-risk: moderate
Directive: Preserve the top-level log/config/hook/branch command wiring together when reconciling future CLI parity rebases
Tested: cargo build --workspace; cargo test -p rusty-claude-cli parses_log_subcommand_with_since_filter; cargo test -p rusty-claude-cli rejects_invalid_log_arguments; cargo test -p rusty-claude-cli cli_git_log_args_include_since_when_requested; ./target/debug/claw log --since 2026-04-01
Not-tested: full cargo test --workspace after the rebase conflict resolution
