chore(release): v1.8.0

Bump csproj + psd1 to 1.8.0 and prepend the 1.8.0 entry to
Staging/ReleaseNotes.md.

The story for 1.8.0 is "the AI sees what the script does." Five
output channels that pre-1.8 silently bypassed the AI's view —
Write-Verbose, Write-Debug, [Console]::* direct writes, native exe
stderr, What if: text and direct \$Host.UI.WriteLine — all reach the
AI now, and Output / Error / Warning / Verbose / Debug interleave in
a single chronological pipeline so an event's position in the run is
preserved instead of collected at the end of a separate
"=== ERRORS ===" section. Plus the busy-console auto-route folds the
old "Pipeline NOT executed - verify and re-execute" round-trip into
a single tool call, and a new LastExit: N status-line tag stops the
green ✓ badge from hiding non-zero exits from native exes.

+# Version: 1.8.0
+## New Features
+- **Hybrid stream capture: chronological pipeline replaces bucketed sections.** Output, Error, Warning, Verbose, and Debug records now interleave in a single time-ordered text block in the AI response — the AI sees each event in its actual position relative to surrounding output. Pre-1.8 the four separate `=== ERRORS ===` / `=== WARNINGS ===` etc. sections lost the "warning fired between step-A and step-B, then the error hit" context.
+- **Five output channels that used to bypass the AI's view are now captured:**
+  - `Write-Verbose` (was the AI's blind spot that the tool description explicitly called out as "Verbose and Debug streams are NOT visible to you").
+  - `Write-Debug` (same).
+  - `[Console]::WriteLine` / `[Console]::Error.WriteLine` direct writes (and any .NET interop that writes to `System.Console` without going through PowerShell streams) → new `=== CONSOLE.OUT (direct) ===` / `=== CONSOLE.ERR (direct) ===` sections.
+  - Native exe stderr (`cmd /c "..."`-style) → ErrorRecord in the chronological pipeline, in emit order alongside surrounding output.
+  - `What if:` text from `$PSCmdlet.ShouldProcess` and direct `$Host.UI.WriteLine` calls → new `=== HOST.UI (direct) ===` section.
+- **Auto-route on busy console.** When `invoke_expression` finds the chosen PowerShell console busy with a user-typed or another AI command, the proxy now spawns a new console at the *source's cwd* and re-runs the pipeline there in the same tool call. Pre-1.8 the AI got `Pipeline NOT executed - verify location and re-execute` and had to re-send manually with whatever cwd they wanted, costing two MCP round-trips for every busy race.
+- **`LastExit: N` status-line tag** surfaces the case where a pipeline overall succeeded (`$?` is true) but a native exe within it returned non-zero. The green ✓ badge no longer silently hides those signals.
+
+## Improvements
+- Real-time streaming preserved through the new capture wiring — items render to the visible console as they arrive, not collected and rendered after the pipeline finishes.
+- Color preserved on the visible console for every stream type: red `Write-Error`, yellow `WARNING:`, yellow `VERBOSE:` / `DEBUG:` prefixes, and `Write-Host`'s user-chosen `ForegroundColor`.
+- `Write-Progress` is suppressed during AI-initiated commands. Real-time bar text is unreadable to the AI as a snapshot, and ConPTY was leaking progress redraw bytes into subsequent commands' captured output. User-typed commands at the visible terminal keep their normal progress display.
+
+## Internal
+- New `TeeTextWriter` for `[Console]::Out` / `[Console]::Error` tee, written to in parallel with the original streams so visible-console output is unaffected.
+- New `TeePSHostUserInterface` decorator wrapping `$Host.UI` (reflected swap on `_externalUI`) for host-UI-level capture of `Write/WriteLine` paths that bypass both PowerShell streams and `[Console]::Out`.
+- Stream merge map widened to `2>&1 3>&1 4>&1 5>&1`. Stream 6 (Information) remains unmerged so `Write-Host`'s user-chosen `ForegroundColor` survives to the visible console.

 # Version: 1.7.7
 ## New Features
 - Authenticode-signed Windows binaries (`PowerShell.MCP.dll`, `bin/win-x64/PowerShell.MCP.Proxy.exe`) so the module is accepted on WDAC / Device Guard machines with a one-time trust of the signer. Closes #46.
