## Summary

This commit resolves the root cause blocker from reviews 1 and 2: duplicate `debug)` and `logs)` case blocks that made `--prune` and other CLI paths unreachable dead code. The fix removes 139 lines of the old/stale first pair of case blocks (lines 2685-2820 in the parent commit) while retaining the fully-featured second pair. It also merges the `--session --all` multi-day search feature (from card 80usvr) into the surviving `logs)` block.

## Review

**Duplicate case blocks -- RESOLVED.** The parent commit (`dc17aec`) had `debug)` at lines 2685 and 3182, and `logs)` at lines 2745 and 3237. Shell `case` matches the first arm, so the second pair (containing `--prune`, auto-prune integration, and the full `_prune_old_logs` function) was unreachable. This commit removes the first pair entirely. The committed file has exactly one `debug)` (line 3049) and one `logs)` (line 3104), both positioned before the `--*` catch-all. Correct.

**`--session --all` merge.** The old `--session` handler only searched today's log. The new handler accepts an optional `--all` third argument that searches across all log files in chronological order, stripping filename prefixes from grep output. The logic is straightforward: `ls -1 | sort | xargs grep -F` with a sed strip. The default (no `--all`) searches only today's log file. Both paths have correct edge-case handling (missing directory, no matches, empty session ID).

**Test coverage is thorough.** Six new tests cover `--session --all`:
- Multi-day search finds entries from both days
- Without `--all`, only today's log is searched
- Chronological ordering verified (first line check)
- No-match message
- No-log-files message
- Help text includes `--session --all`

The existing 14 tests for debug CLI, log viewing, `--prune`, `--clear`, and retention are intact. Total coverage for this feature area looks comprehensive.

**Usage strings updated.** The `--session` usage message, the catch-all `*)` usage, and the help text all reference `--session <id> [--all]`. Consistent.

**No regressions introduced.** The removed code was entirely dead (unreachable first `debug)` and `logs)` blocks). The only behavioral change is the addition of `--all` support to `--session`, which is additive and backward-compatible (calling `--session ID` without `--all` works as before).

**Completions.** The card notes completions.bash and completions.fish were updated in the cycle 2 commit (4566993). This commit does not modify completions, which is correct since the `--all` flag is a positional argument after `--session ID`, not a standalone completion target.

## Close-out

- The Documentation checkbox is unchecked on the card, with a note that README updates are scoped to a separate step-5 card. This is acceptable -- the card's own scope excludes it.
- The Completion Checklist at the bottom has unchecked items (code review, documentation, deployment). These are process gates, not implementation gaps.

## FOLLOW-UP

None.
