release: prepare 1.1

[yannrichet-asnr]

Repo-side preparation for the 1.1 release. Does not publish — that happens when a GitHub Release (tag 1.1) is published, triggering release.yml.

Changes

• Version bump → 1.1 in fz/__init__.py (the single source; pyproject.toml reads it via attr = "fz.__version__", and fz/_version.py is CI-stamped — left untouched).
• NEWS.md — cut ## Unreleased to ## Version 1.1 (2026-06-15) and opened a fresh empty ## Unreleased. 1.1 collects everything merged this cycle: CLI argument aliases, calculator-discovery fixes, the fzd CLI execution fix, recursive directory-tree staging, fzd input-flag aliases, CLI hardening, and the two worked skill examples + skill hardening.
• README version badge 1.0 → 1.1.
• Skill docs — flipped the "git main / next release" caveats to "fz ≥ 1.1" (fzd auto-discovery, recursive case-subdir staging, --calculators <alias>, fzd input-flag aliases, positional paths), bumped install hints to funz-fz>=1.1 where a feature needs it (directory-case codes, CLI fzd), and kept accurate "fz 1.0 only" notes for what changed.

Verification

• import fz; fz.__version__ → 1.1.
• tests/test_skill_static.py green (the skill-claim drift checks).
• Version tests are regex-based (\d+\.\d+); no test hard-codes 1.0.

After merge — cutting the release (your call)

Create a GitHub Release: tag 1.1, title "fz 1.1", notes from the NEWS 1.1 section. That triggers the wheel build (Py 3.9–3.14 × 3 OSes) and the PyPI publish via trusted publishing.

Pull request overview

Repo-side prep for the fz 1.1 release by bumping the package version and aligning release notes + documentation to reference 1.1 behavior/features.

Changes:

• Bump fz.__version__ from 1.0 → 1.1 (setuptools dynamic version source).
• Cut release notes by adding a Version 1.1 (2026-06-15) section and leaving a fresh Unreleased header.
• Update README badge and skill/docs/examples to state fz ≥ 1.1 requirements (notably fzd fixes, calculator auto-discovery, and recursive directory-tree staging).
