bug: dry-run shows malformed stale message — missing duration string

[claude]

Description

When the cache is stale, uncompact dry-run renders the stale warning without the age duration, producing output like:

> Injected by Uncompact at 2026-02-27 12:00:00 UTC | ⚠️ STALE: last updated

instead of:

> Injected by Uncompact at 2026-02-27 12:00:00 UTC | ⚠️ STALE: last updated 3.2 hours ago

Root Cause

In cmd/status.go:245, store.Get() returns five values (graph, fresh, expiresAt, fetchedAt, err), but expiresAt and fetchedAt are silently discarded with _:

cachedGraph, fresh, _, _, err := store.Get(proj.Hash)

Then RenderOptions is built without StaleAt:

opts := tmpl.RenderOptions{
    MaxTokens:     maxTokens,
    Stale:         !fresh,
    WorkingMemory: wm,
    // StaleAt is missing!
}

In internal/template/render.go:99-101, StaleDuration is only populated when opts.StaleAt != nil:

if opts.Stale && opts.StaleAt != nil {
    data.StaleDuration = humanDuration(now.Sub(*opts.StaleAt))
}

So StaleDuration stays "" and the template emits a trailing space with no time string.

Fix

Capture expiresAt from store.Get() and pass it as StaleAt in RenderOptions:

cachedGraph, fresh, expiresAt, _, err := store.Get(proj.Hash)
// ...
opts := tmpl.RenderOptions{
    MaxTokens:     maxTokens,
    Stale:         !fresh,
    StaleAt:       expiresAt,
    WorkingMemory: wm,
}

Affected file: cmd/status.go, dryRunHandler function (~line 245).

@claude please implement this

Fix implemented

• Gather context and understand the issue
• Read cmd/status.go to locate the dryRunHandler function
• Apply the fix (capture expiresAt, pass as StaleAt)
• Verify build passes (go build ./...)
• Commit and push changes
• Create PR

Change made in cmd/status.go:245:

// Before
cachedGraph, fresh, _, _, err := store.Get(proj.Hash)
// ...
opts := tmpl.RenderOptions{
    MaxTokens:     maxTokens,
    Stale:         !fresh,
    WorkingMemory: wm,
}

// After
cachedGraph, fresh, expiresAt, _, err := store.Get(proj.Hash)
// ...
opts := tmpl.RenderOptions{
    MaxTokens:     maxTokens,
    Stale:         !fresh,
    StaleAt:       expiresAt,
    WorkingMemory: wm,
}

expiresAt is now passed as StaleAt, so render.go can compute humanDuration(now.Sub(*opts.StaleAt)) and populate StaleDuration — matching the pattern already used in cmd/run.go.
