feat(FN-5171): add near-duplicate task guard to CLI create command

Browse Source 
Adds a near-duplicate guard to the CLI task creation command (FN-5171), preventing creation of tasks with titles that are visually or semantically identical to existing ones, with 262 new test cases covering the detection logic and the standard changeset entry.

Layer FN-5152's near-duplicate intent guard onto the CLI `fn task create`
direct-store path. Aligned thresholds (≥2 shared high-signal tokens AND
title-token Jaccard ≥ 0.30 within a 7-day window), `--no-dedup` bypass,
`source.sourceMetadata.intentSignature` stamping, and fail-open semantics
match the dashboard `POST /api/tasks` gate. Non-TTY runs refuse with exit
1; TTY runs prompt before creating. GitHub-import and AI-planning paths
intentionally skip the gate (FN-5060 contract).
