Brings the staging branch up to date with main's feature-fix stream so
every staging-targeted PR stops tripping on pre-existing rot. Before
this merge, staging had 30+ compile + test failures from fix PRs that
landed on main but never reached staging — primarily #1755's panic-
cascade + schema-drift alignments.
After this merge the handlers package goes from 30+ fails → 2 pre-
existing nil-docker test panics (TestCopyFilesToContainer_CWE22_
RejectsTraversal + TestDeleteViaEphemeral_F1085_RejectsTraversal),
both authored on staging and broken before this promotion. Tracked
separately; not a merge regression.
## Conflicts resolved
1. docs/marketing/campaigns/discord-adapter-announcement/announcement.md
— deleted on main (9d0d213: "move sensitive strategy + research to
internal repo"), modified on staging. Deletion wins: marketing
content moved out of the public monorepo per that commit's intent.
The content lives in the internal repo.
2. workspace-server/internal/handlers/container_files.go — staging's
rmTarget version kept. Main's version had `Cmd: []string{"rm",
"-rf", "/configs/" + filePath}` which concatenates raw filePath
AFTER the prefix-check on rmTarget, defeating the path-traversal
guard (a "../etc/passwd" input passes validation but the rm cmd
then traverses). Staging's `Cmd: []string{"rm", "-rf", rmTarget}`
uses the validated path. Keeping staging's more-secure variant.
## Includes build unblockers from #1769 / #1782
- terminal.go: malformed handleLocalConnect repaired
- terminal_test.go: missing braces in TestHandleConnect_RoutesToLocal
- workspace_crud.go: unused imports + duplicate strField block
- container_files_test.go: duplicate contains() removed (uses the one
in workspace_provision_test.go, same package)
## Verification
- go build ./... ✅ clean
- go vet ./... ✅ clean
- go test -race ./... — 18/20 packages green; 2 test panics in
internal/handlers are pre-existing on staging (documented above)
