v1.19.0

Features

• Find the tasks that carry a link. (#37) GET /api/v1/tasks?link=<url> keeps the tasks whose links — formal, title, or body — include that URL, and composes with scope (archived and all included) and every other filter, so "does this Slack thread already have a task?" is one request instead of paging every task. The CLI twin is tasks links --url <url> (with --all to reach done and archived tasks). Both match through one rule, links.MatchKey: scheme and host case, a leading www., a default port, the fragment, a trailing slash, utm_*/fbclid/gclid, and Slack's thread_ts/cid on a Slack permalink are ignored, percent-escapes are decoded, and the remaining query is compared order-insensitively; a query that addresses a resource (?p=/notes/review.md) still distinguishes links. /meta advertises capabilities.link_filter.
• Links into local documents can be classified as doc. (#38) The new doc_link_patterns config (whitespace-separated whole-URL patterns, * wildcard — for example doc_link_patterns = http://127.0.0.1:8080/open?p=*) classifies matching links as the doc system ahead of any host row, so tasks links --system doc and the API's links[].system tell "where this task came from" apart from context links without client heuristics. /meta and tasks config publish the patterns. The classifier also names file: URLs and relative .md/.txt paths doc, but stored and extracted links remain http/https only, so today a document link reaches a task through a pattern-matched web URL.

Behavior changes

• GET /api/v1/tasks/{id} finds an archived task. (#36) Without source, the read now falls back to the archive when no live task has the id, returning the resource with source: "archive", so a client resolving a cited id no longer pages the archived scope. A client that read a 404 there as "this task left the live file" should check source instead. The live task still wins when both share an id, and an explicit source=live or source=archive stays exact. Writes keep refusing archived tasks. /meta advertises capabilities.archive_fallback.
