Bumps the training environment to Nextflow 26.04.4 (from 25.10.4) and refreshes the materials to match.

This is not a find-and-replace. Nextflow 26.04 makes the v2 syntax parser the default, and console output, file listings, and some behaviours change versus 25.10. Every runnable tutorial was re-run end-to-end on 26.04.4 (in Docker, NXF_VER=26.04.4) and its documented output regenerated from genuine runs. No fabricated or hand-edited output.

What changed

  • NXF_VER26.04.4 in both devcontainer configs.
  • info/nxf_versions.md rewritten: the "v2 parser will become the default in 26.04" statements are now present-tense, and the loaded-version note is 26.04.4. The supported floor stays 25.10.2 (still valid with the v2 parser enabled).
  • All console blocks, Outputs: summaries, error text, and file listings refreshed from real 26.04.4 runs across the modules below.

Verified on 26.04.4 (default v2 parser)

  • hello_nextflow (Parts 1-6)
  • nextflow_run + envsetup
  • nf4_science — genomics + rnaseq (VCFs byte-matched) and imaging/molkart (full 22-task run on native x86)
  • side_quests — all 9 (debugging, dev_environment, essential_scripting_patterns, metadata, nf_test, plugin_development, splitting_and_grouping, workflows_of_workflows, working_with_files), each verified by a dedicated run
  • Consistency pass: heading numbering, prettier, hl_lines, internal hash consistency

Confirmed across every module: 26.04 required no script changes — the v2-syntax scripts already parse and run cleanly. All real changes are console-output formatting: the version banner, the Launching line dropping DSL2, the process status line ([hash] NAME | N of M ✔), and the new end-of-run Outputs: summary block.

Incidental fixes (found along the way)

  • hello_nextflow/04: stale greeting param corrected to input (mismatched the solution; would null params.input).
  • hello_nextflow/05 + nextflow_run/02: cowpy demos used the positional form (cowpy "Hello Containers"), which doesn't put the text in the speech bubble (cowpy reads stdin). Switched to the stdin form so the documented output matches, consistent with how the pipeline module invokes cowpy.
  • nf4_science/rnaseq/03: MultiQC data-dir listing refreshed to current tool output.
  • nf4_science/imaging: was lagging at 25.04.3; brought up to 26.04 and made v2-safe by switching molkart's documented integer params from CLI flags (which arrive as strings under the v2 parser and fail validation) to a typed params.yaml. Also fixed a fabricated resume block and a wrong task count.

Deliberately scoped out (one follow-up)

  • hello_nf-core stays on the v1 parser in this PR (orientation instructs export NXF_SYNTAX_PARSER=v1). The course is verified working end-to-end on 26.04.4 under v1 (Part 1's nextflow pull exploration steps were updated for 26.04's new on-disk layout, and the full nf-core/demo run completes). Running it under the v2 default needs a content change (the nf-core --validate_params false CLI pattern is a no-op under v2 — Using strict syntax causes template to raise an error when setting boolean options on CLI nf-core/tools#4100, still open) and a migration to the nf-core tools 4.0 template. That modernization is a stacked follow-up PR (hello-nf-core-tools-4.0, solutions already migrated and verified).

The positional form 'cowpy "Hello Containers"' does not put the text in the
speech bubble (cowpy reads the message from stdin); it printed the cowacter
self-description. Use the stdin form, matching how the pipeline module invokes
cowpy, so the documented output is what the command actually produces. [skip ci]

…a typed params.yaml

Validated end-to-end on native x86 (22-task molkart run). Resolves the v2
integer-param typing issue (--flag value ints arrive as strings under the v2
parser) by switching documented commands to a typed params.yaml; also fixes a
fabricated resume block and a wrong task count. [skip ci]
