Changelog

HasDistinctSummary was comparing the full summary (including trailing

"...") against the content via StartsWith. Since the content doesn't

contain "..." at the truncation point, the match always failed and

the redundant preamble kept showing.

Now strips trailing "..." from the summary before the prefix comparison.

Root cause: .NET's HttpClient resolves DNS and tries connecting to the

first address returned (typically IPv6 AAAA record). When the network

cannot route to the IPv6 address, the connect attempt blocks for the

full request timeout (30-60s) before giving up — unlike curl which uses

Happy Eyeballs (RFC 8305) to try both protocols in parallel.

Confirmed by testing: IPv6 connect to privstack.io hangs indefinitely

while IPv4 connects in ~45ms. This affects any host that publishes

AAAA records not routable on the user's network.

Fix: replace the default SocketsHttpHandler with a custom ConnectCallback

that implements Happy Eyeballs — resolves all addresses (IPv4 + IPv6),

initiates connections to all in parallel, uses whichever succeeds first,

and cancels the rest. This brings feed fetch from timeout (30-60s) down

to ~350ms for affected hosts.

Also adds gzip/deflate decompression support to the handler.

• Use HttpCompletionOption.ResponseHeadersRead in FetchFeedAsync and

RefreshFeedAsync so the response streams immediately after headers

arrive, enabling progressive XML parsing instead of buffering the

entire body first

• Add OperationCanceledException catch clauses that distinguish between

HttpClient timeout (user-friendly "server may be slow or unreachable"

message) and explicit user cancellation

• Increase default HttpClient timeout from 30s to 60s since RSS feeds

from smaller servers can be slow, and streaming now provides visual

feedback during the wait

• Add CancellationTokenSource to AddFeedAsync in RssViewModel so users

can cancel a slow feed fetch via CancelAddFeedCommand

Adds a new search intent that allows the AI to actively search tasks by

title, description, tags, or status. Uses SDK search with fuzzy fallback

(Contains matching) to catch partial matches. Supports optional status

filter and configurable max results. Also updates PLUGIN_CONTEXT.md to

document all five task intents.

• Update intent description and slot descriptions to guide the LLM:

forward-looking queries use 30-day lookahead without period clipping,

strict queries use calendar boundaries

• Group results by month in summary output so the AI can respond

naturally: "You have a lunch on the 27th, then in March you have..."

• Include day-of-week in event timestamps (e.g. "Thu Feb 27, 12:00 PM")

for more conversational responses
