feat(hooks): title sessions host-project with a hyphen, no space

The SessionStart hook joined host and project with a space ("ratio rulesets"), which reads as two words in the claude.ai/code and mobile session lists. I changed the join to "$host-$project" ("ratio-rulesets") so the title is one token, and updated the three session-title-hook.bats expectations test-first.
