Fix canvas repo detection and shrink oversized preview images (#2227)

Browse Source 
Canvas extensions (accessibility-kanban, where-was-i) resolved git state
against the extension's install directory or the session-state folder
instead of the repo the session was opened in. This broke repo/branch
detection for user-scoped installs and worktrees ("unknown/unknown",
"detached HEAD"). Both now read the active session's working directory
from the canvas request context on open and on each action, so they
follow whichever project/worktree opened them.

where-was-i also re-gathers context on open when the saved branch is
blank, so it never opens stuck on stale data.

Also compress oversized extension preview images (pngquant, with a mild
resize for the photographic arcade-canvas art) so every preview.png is
comfortably under the installer's inline-byte cap that was blocking
release-notes-showcase from installing.

Update release-notes-showcase author to Kayla Cinnamon.
