refactor(examples)!: remove two example bundles; 0.2.0 in CHANGELOG

Replaces sector-specific example material with generic, fictitious
examples: removes the two full-scale example bundles under examples/ (18
files) and every reference to them in README Contents and CHANGELOG
(neutral wording in the 0.1.0 entry; history untouched). The
falsification-reviewer worked example now uses a building-energy scenario
with the same structure, judgement (undecided) and evidence states. One
word in the author's own commentary in docs/plan/ is made generic; the
quoted source text is unchanged.

Remaining examples: bygg-energi-mikro, nav-golden-hierarchy,
nav-golden-escape.

Cuts [Unreleased] as [0.2.0] - 2026-09-23 with its link reference.
CHANGELOG.md is the only file that carries the repository version. No tag.

scripts/check-excluded-topics.py: red (180 hits / 20 files / 68 paths)
-> green (0 hits / 50 tracked paths, self-test passed), measured after
git add with the local term list in place.

Valgt 0.2.0 fordi fjerningen er brytende for konsumentene, og pre-1.0
semver bærer brudd som minor-bump. Valgt én commit for fjerning og
versjonskutt fordi CHANGELOG-teksten for begge er samme endring.

BREAKING CHANGE: consumers that vendor shared/examples/ lose the two
directories on the next subtree pull.

+  `bygg-energi-mikro` (the dev fixture with its golden suite) and the `nav-golden-hierarchy` /

+  now uses a building-energy scenario (daylight-responsive lighting control in an office
+  building). The structure, the judgement (`undecided`), the evidence states and every rule the
+  example demonstrates are unchanged; only the concept ids, titles and claim text changed.

 ### Added
 
+- **[`scripts/check-excluded-topics.py`](scripts/check-excluded-topics.py)** — a repository
+  hygiene gate: fails if any tracked path or text file matches a term list kept outside the tree,
+  in `<git-common-dir>/info/excluded-topics`. It runs a self-test first (known positives must
+  match, known negatives must not) and exits 2 rather than report a clean scan from a pattern that
+  cannot find; without the term list it reports SKIPPED and exits 3.
