Add completion spec: Nextflow

[lucieleblanc]

Summary

Add comprehensive completion spec for the Nextflow CLI, a reactive workflow framework for data-driven computational pipelines. Nextflow is downloaded 150,000+ times/month and has significant demand in the bioinformatics/genomics community (16 upvotes on GitHub #3397).

What's included

JSON Spec (command-signatures/json/nextflow.json)

• 17 subcommands: run, clean, clone, config, console, drop, fs, help, info, kuberun, list, log, node, plugin, pull, secrets, self-update, view
• 11 top-level options: -C, -D, -bg, -c/-config, -h, -log, -q/-quiet, -remote-debug, -syslog, -trace, -v/-version
• Full run/kuberun options: container runtimes (Docker, Singularity, Apptainer, Podman, Charliecloud, Conda), reports, DAG, timeline, tracing, Tower integration, pipeline parameters
• Nested subcommands: fs (cat/copy/delete/list/move with aliases), secrets (list/get/set/delete), plugin (install)
• File/folder templates where appropriate (config files, work dirs, params files, DAG output, etc.)
• Static suggestions for hub types, boolean flags, output formats

Rust Generators (src/generators/nextflow.rs)

• run_names: Runs nextflow log -q to suggest previous run names for clean and log commands
• downloaded_projects: Runs nextflow list to suggest cached projects for info, drop, and view commands

Generator verification

Both generators were tested end-to-end in a local Warp build against this branch. Screenshots are in the PR comments below.

run_names generator (nextflow clean + Tab):
Completions dropdown shows test_run_screenshot with "Run name" description, followed by clean options (-after, -before, -but, -dry-run, -force).

downloaded_projects generator (nextflow info + Tab):
Completions dropdown shows nextflow-io/hello with "Downloaded project" description, followed by info options (-dd, -help, -d, -h, -o).

APP-3501 [Completions] Create `nextflow` completion spec

No spec exists for Nextflow. Need to create spec from scratch covering all subcommands and options. 16👍 on GitHub — significant bioinformatics/genomics user demand. Nextflow is downloaded 150,000+ times/month.

See GitHub #3397
