Intelligent, width-aware directory shortening - #110

Conversation
One central path-display policy (src/prompt/pathDisplay.ts) replaces the ad-hoc HOME substitution. The live prompt tries shortening levels in order and uses the first whose full prompt fits: parents above the repository abbreviate to their shortest unambiguous sibling prefix, then directories inside the repository, then runs collapse to an ellipsis, then only the final directory remains. The repository name and final directory stay whole, HOME stays ~, and prompt snapshots keep the full width-independent path. Abbreviations are resolved asynchronously alongside the prompt context; nothing changes the cwd.

What
src/prompt/pathDisplay.ts. It is display only and never changes the cwd.0. full:
~/Projects/work/notMyShell/src/prompt~/P/w/notMyShell/src/prompt~/P/w/notMyShell/s/prompt…/notMyShell/…/prompt…/prompt(the project module already names the repo)readdirof ancestors, and fall back to the first character. Hidden directories keep their dot.~, and a sibling of HOME is not treated as HOME.PromptContextgainsrootandpathAbbreviations. Prompt snapshots keep the full, width-independent path, so history stays stable.Verification
npm run build,npm run typecheck,npm test,git diff --check.tests/pathDisplay.test.tscovers every level, non-repo paths, HOME,/, trailing slashes, hidden directories, unique-prefix resolution against a real temporary tree, the exact-width sweep 20–160, and snapshot stability.The behavior is fully deterministic and tested at the string level, so no terminal-specific behavior is involved.
