After each iteration's _commit_iteration, record the new HEAD SHA and use
it as the diff anchor for the next iteration. Previously capture_diff
always diffed against the initial base commit, causing every iteration to
return the same full cumulative diff — reviewers couldn't see what changed
between iterations, leading to repeated feedback and stuck FAIL loops.

Claude in agentic mode (interactive, no -p flag) commits its own changes,
advancing HEAD. This made `git diff --cached HEAD` return empty, triggering
false EMPTY_DIFF errors every time. Now capture_diff diffs against the
base commit SHA recorded at worktree creation, so changes are captured
regardless of whether the agent committed them.
Also adds UX_IMPROVEMENT_PLAN.md for guided message improvements.

_finalize_worktree was returning None and deleting the branch when the
final commit was empty, even though _commit_iteration had already
committed changes during the pipeline. Now checks git log for any
commits on the branch before deciding to clean up.

Plan mode causes Claude to spend all time on tool calls (Read/Grep)
in -p mode, producing empty stdout. Reviewers receive full context
(diff, plan, checklist) via the prompt, so file access is not required.
Without --permission-mode, -p mode defaults to read-allowed, write-denied.

- Add -p flag to _CLAUDE_REVIEW_ARGS so reviewer uses print mode (stdin→stdout)
instead of interactive mode which conflicts with plan permission mode
- Copy input files (plan, checklist) into worktree .cross-eval-inputs/ so
agents in plan mode can access them without escaping the sandbox
- Simplify _snapshot_repo_state to use only git diff HEAD + untracked hashes,
eliminating false positives from staging state changes (git diff --cached)
and git status index drift during long-running pipelines

- Carry execution evidence forward so reviewer/senior prompts in
subsequent iterations can inspect prior transcript and command data
- Add {execution_evidence} to REVIEW_ONLY templates (en/ko)
- Add evidence summary table to iteration reports
- Fix test_agentic to match stdin-based prompt delivery for Claude
- Add expanded claim/no-change marker tests and cross-iteration
evidence propagation tests

Claude -p mode tends to describe changes in text rather than actually
applying them via tools. Added explicit rule requiring tool-based edits
so that file modifications produce real git diffs.

Claude -p (print mode) is non-interactive but retains full tool access
(Edit, Write, Bash, etc.) with --dangerously-skip-permissions. Removing
-p caused Claude to enter interactive mode which requires a TTY and
produces zero output when run as a subprocess with piped I/O.
Now delivers prompt via stdin for both Claude and Codex in agentic mode.

Claude Code refuses to launch inside another Claude Code session.
Strip the CLAUDECODE marker from the inherited environment so that
cross-eval can spawn Claude as a subprocess from within Claude Code.

Without -p, Claude enters interactive mode and waits for more input
indefinitely. Setting input="" closes the stdin pipe immediately,
causing Claude to process the positional prompt and then exit.

The agentic invocation path inherited -p (print mode) from _CLAUDE_BASE_ARGS
but only stripped the stdin sentinel "-". Print mode makes Claude a one-shot
text completer that cannot use tools or write files, resulting in zero diffs.
