fix(hooks): derive project wing from non-macOS transcript paths (#1145)

_wing_from_transcript_path only matched '-Projects-<name>' segments,
so Linux users with code under ~/dev/, ~/code/, or ~/src/ fell through
to the wing_sessions fallback and lost the per-project diary scoping
introduced in #659.

Broaden the heuristic to derive the project from the final
dash-separated token of the encoded project-folder name under
.claude/projects/. Keeps the legacy -Projects- regex as a secondary
match for transcripts living outside the standard Claude Code path.

Covers macOS Users layout, Linux dev/code layouts, and deeper nested
source paths while preserving existing Projects/ behavior.
