fix(cli): wire /sessions slash command in the classic CLI

[teknium1]

Salvage of #25231 by @explainanalyze, cherry-picked onto current main with authorship preserved.

Summary

Wires /sessions into the classic CLI's process_command() dispatcher. The command has been in COMMAND_REGISTRY since #20805 and surfaces in /help + tab-completion, but the legacy CLI never grew an elif canonical == "sessions" branch — so it fell through and printed Unknown command: sessions in both Windows and WSL/Linux CLI (reproduced by @gille).

Changes

• cli.py: _handle_sessions_command() + dispatch branch. No-arg / list / ls / browse → recent-sessions table (same one /resume prints). Other args → delegate to _handle_resume_command(f"/resume {arg}").
• tests/cli/test_cli_init.py: 4 regression tests covering bare /sessions, /sessions list, target delegation, and dispatcher wiring.
• scripts/release.py: AUTHOR_MAP entry for @explainanalyze (separate commit).

Validation

• scripts/run_tests.sh tests/cli/test_cli_init.py -k sessions → 6/6 pass.
• E2E in isolated HERMES_HOME: /sessions prints recent table, /sessions list works, /sessions <target> delegates to _handle_resume_command("/resume <target>").

Closes #25231 via salvage. Original commit authored by Phil Thomas phil.thomas@gametime.co.
