feat(feedback): support attaching logs and codebase (#1120)

* feat(feedback): support attaching logs and codebase

Add an attachment picker to /feedback (none / logs / logs + codebase).
Codebase uploads scan the working directory with sensitive files excluded
and are sent through a new multipart upload API on the oauth/node-sdk layers.

* fix(feedback): fall back to logs when codebase scan fails

* tiny fix

* fix(feedback): make diagnostic uploads partial-safe

* refactor(feedback): reuse harness session export and normalize upload url types

* docs(slash-commands): note optional feedback attachments

* refactor(feedback): reorganize feedback upload modules

Move the attachment orchestration out of tui/commands/info.ts into a
dedicated feedback/feedback-attachments.ts, and split the former
codebase-upload/attach.ts into a generic multipart uploader
(feedback/upload.ts) and an archive lifecycle module
(feedback/archive.ts). Both session and codebase archives now flow
through a single upload lifecycle, which also removes the temp-dir
leak that occurred when codebase packaging failed.

Rename FeedbackCodebaseArchive to FeedbackArchive and the
codebase-upload/ directory to codebase/ so module boundaries match
their actual responsibilities (scan + package only).
