v0.15.2-fork.4

Features

• The welcome crab scuttles while the session connects and waves once when it connects, then rests; nothing animates at idle and prefersReducedMotion keeps it still.

Fixes

• Slash-command suggestions rank an exact name first, then name prefixes, then prefixes of a name's segments, then other matches, so /res shows /resume first.
• The trust prompt shows the directory being trusted (the stored project key), keeping the end of a long path visible on short screens.
• /export names default files export-<session-id>-<YYYYMMDDTHHMMSSZ>.md and suffixes collisions -2, -3; it never overwrites a file.
• Starting without a terminal exits 25 with one line instead of writing escape sequences and a runtime log; piped stdin still works when /dev/tty is available.
• --dir and --bridge-script are checked before startup.
• Session flags apply to interactive launches only (the root command and resume); errors name the flag and the subcommand.
• A one-word prompt that is a one-slip typo of a command (claude-rs doctr) is refused with a suggestion; claude-rs -- doctr sends it.
• Shell completions no longer offer hidden subcommands; help shows two usage lines, a Diagnostics Options heading, and documents exit status and environment variables.

Breaking

• --log-append now requires --log-file (it used to append to a legacy log with no retention).

Upstream

• Merges upstream main at a187e1c: zip 9, the CONTRIBUTING scope-agreement section, the merged srothgan#444, and dependency updates.
