Cursor Agentand陈大猫 a608507586 fix(window): let close blur the focused field during inline rename
Minimize and maximize still suppress mousedown focus so restore keeps the terminal focused. Close does not, so session and host-group renames can commit on blur.

Cursor Agentand陈大猫 6c7338463d fix(window): keep terminal focus when clicking title-bar window controls
Prevent the frameless minimize, maximize, and close buttons from taking
DOM focus on mousedown so restore from the taskbar leaves the terminal
textarea focused.

GOUKI9999 d14591b36a fix(ai): raise CLI version-probe timeout so slow-starting CLIs are discovered
Bun-compiled OpenCode-family CLIs answer --version slowly: measured
'mimo --version' at 3.9-5.1s warm (6s+ cold) and 'opencode --version'
at 6s cold on Windows. The 5s probe timeout killed these healthy CLIs
mid-probe, so agent discovery dropped them (exitCode null ->
not plausible) and the settings card showed them as unavailable. Raise
the version-probe timeout to 15s; a missing command still fails spawn
immediately, so only existing-but-slow CLIs pay the extra wait.

aa597135b1 ci: narrow spam-comment filter and relay comment edits (#3752)
* ci: hide only risky download links in issue comments

Stop deleting comments that merely mention an archive or executable
name. Match http(s) URLs whose path contains a risky extension, skip
the issue author as well as maintainers and bots, and minimize matches
as spam instead of deleting them.

Co-authored-by: 陈大猫 <binaricat@users.noreply.github.com>

* ci: relay edited issue comments with truncated bodies

Forward issue_comment edited events and include comment identity,
association, timestamps, and bodies clipped to 4000 characters.

# Agent Note: Keep port forwarding usable when host OS metadata is missing
Status: implemented
## Problem
[Issue #3748](https://github.com/binaricat/Netcatty/issues/3748) reports that the
port-forwarding page displays `Port forwarding could not load.` when rendering
a selected host whose legacy `os` value is absent, null, or an empty string.
`EditPanel`, `NewFormPanel`, and both host-selection steps in `WizardContent`
evaluate `selectedHost.os[0].toUpperCase()` while constructing `DistroAvatar`
props. Missing or null values fail on indexing; an empty string fails on
`toUpperCase`. This happens before the avatar can render its generic icon.
Although `Host.os` is required by TypeScript, persisted runtime records can lack
that metadata. The original source of the affected records is not established.
## Decision
The four call sites use `(selectedHost.os || 'unknown').charAt(0).toUpperCase()`
to keep the required string fallback safe without changing the shared avatar
API. Valid OS values retain their existing initials. Missing and empty values
use the explicit unknown fallback, and the avatar keeps its existing generic
icon behavior.
The fix stays in the affected presentation code. It does not change host data,
normalization, persistence, or tunnel lifecycle behavior. A shared helper for a
single short expression would add indirection without a separate responsibility,
so the four call sites use the same expression directly.
## Validation
`components/PortForwardingPanels.test.tsx` renders the real components with
`react-dom/server`, the existing i18n provider, and the tooltip provider. It does
not mock the panels or avatar and does not inspect their source text.
The table-driven cases cover all four entry points, all three forwarding types,
and missing, undefined, null, empty, Linux, Windows, and macOS values. Separate
checks preserve distro icons and host-picker behavior when no host is selected
or the selected host is no longer available. Invalid legacy fixture shapes use
one explicit type assertion rather than weakening the production `Host` type.
Before the fix, 48 of the 96 new cases fail with the reported TypeError; the
other 48 pass. After the fix, all 96 pass. Together with the existing avatar,
port-forwarding toolbar, and utility tests, the focused run passes 109 tests:
```sh
node --test --import tsx components/PortForwardingPanels.test.tsx \
components/PortForwardingNew.test.ts components/portForwardingUtils.test.ts \
components/DistroAvatar.test.tsx --test-concurrency=2
```
These are rendering regression tests, not SSH or network end-to-end tests.
Additional checks against upstream commit `786a317`:
- `npm run build` succeeds.
- `npm run lint` succeeds with the same eight existing warnings as upstream.
The four changed TypeScript/TSX files also pass lint with `--max-warnings=0`.
- `LC_ALL=C npm test -- --test-concurrency=1` runs 13,986 tests: 13,944 pass,
four fail, and 38 are skipped. An unmodified upstream worktree runs 13,890
tests with the same four failures and 38 skips, so this change adds 96 passing
cases without adding a failing case. The baseline failures are the SFTP
large-directory persistence timing test, two Bash OSC 7 setup tests, and the
README clipboard-paste screenshot-dimension assertion. The SFTP timing test
passes in isolated runs on both checkouts but fails in these full-suite runs.
A non-English locale additionally causes the existing fish error-message
assertion to fail; both comparison runs use the C locale.
- The full-project `tsc --noEmit --pretty false` check has 759 existing errors.
Its complete output matches the unmodified upstream output after normalizing
checkout paths; none of the changed files has a diagnostic. This is not a
claim that full-project type checking passes.
### Upstream CI follow-up
The original PR CI run [39215269619, attempt 2](https://github.com/binaricat/Netcatty/actions/runs/39215269619/attempts/2)
passes all 96 new regression cases and fails only the existing README paste
assertion. Upstream commit `b366967` fixes that assertion by removing its
coupling to changing screenshot dimensions. The branch incorporates this fix
through a normal merge of upstream `main` at `42b8e2f`, without rewriting the
original fix commit or adding an independent change to the unrelated test.
After synchronization, the focused run including the entire clipboard-paste
test file passes 149 tests. Lint and the production build also pass; lint keeps
the same eight existing warnings. The earlier full-suite and type-check
comparison above describes the original `786a317` baseline, not the updated
base. Current remote CI results are tracked on the PR.
## Alternatives considered
- Remove the unused fallback prop from the four calls: the shared avatar still
requires it in its TypeScript contract. Changing that API and cleaning up all
callers is unnecessary for this targeted bug fix.
- Normalize or rewrite stored host records: broadens the persistence scope,
obscures the rendering assumption, and cannot replace guarding optional
runtime metadata at the point of use.
- Add a new avatar wrapper or fallback utility: unnecessary for this small
expression and would expand the production change without improving the
boundary being fixed.
## Consequences
Incomplete host OS metadata no longer prevents new/edit panels or wizard
host-selection steps from rendering. Existing icons, component contracts, and
host records remain unchanged. The guard is local to port forwarding; auditing
unrelated callers or redesigning the unused fallback API remains out of scope.
