Update plugin entry: file-tree

[fzrx-ego]

Summary

Update the existing File Tree community listing (file-tree) to the 0.17.0 release.

File Tree keeps the thread workspace on the right of the conversation. Search finds a file by name or path, a click opens the preview, and the context menu can add a relative path to the draft, create a blank markdown file, delete a file, copy a path or the file, or reveal it in Finder. 0.17.0 adds Seti-style type icons in the tree and search (markdown, JSON, gitignore, env, and other common names); folders keep only the twistie.

This change updates source.git.range and description on a published v1 entry. Please add the v1-change label if CI requires it.

Release source

• Git: https://github.com/fzrx-ego/bb-plugin-file-tree.git
• Range: ^0.17.0 (immutable tag v0.17.0 → 8348aea78fbedd6cc4f70a52f61cc770c03d6e44)
• Account opening this PR: fzrx-ego (matches author.github)

Plugin checks

• node --test lib/file-type.test.ts src/blank-markdown.test.ts passed
• tsc --noEmit passed
• bb plugin build produced dist/server.js and dist/app.js
• Plugin ID derives to file-tree

Marketplace checks

• npm run build produced dist/v2/marketplace.json with 232 entries
• npm run check (--liveness) not re-run for the full catalog (previous run timed out on unrelated entries); this entry's tag v0.17.0 is on GitHub
• Entry fields stay within marketplace-v2 schema; category file-viewers-and-editors; icon host name Folder
• Overview copied from the plugin repository PLUGIN_OVERVIEW.md (2529 characters; dropped a Cursor product comparison)

Permissions and security

• Full-trust BB plugin with local file access on the machine that owns the workspace
• Create/delete go through a server-side rootId registry, then resolveUnderRoot (no client-supplied host/path)
• Delete refuses the workspace root and directories; create uses unique untitled.md / untitled-N.md names and expectedSha256: null so it does not overwrite
• Finder reveal is macOS-only (open -R)

Screenshots

None. The current published listing also has an empty screenshots array. This harness cannot capture BB's Electron UI. Screenshots can be added in a follow-up if wanted.

Overview source

Copied from PLUGIN_OVERVIEW.md in fzrx-ego/bb-plugin-file-tree at tag v0.17.0, with the Cursor comparison removed for marketplace listing rules.

v0.18.0 is now tagged on fzrx-ego/bb-plugin-file-tree. npm semver treats ^0.17.0 as >=0.17.0 <0.18.0, so merging this range would not select that tag.

#341 keeps this description and overview and sets the range to ^0.18.0.
