test: remove wording-pinning tests of model-facing prose across both suites (#3031)

Browse source 
* test: replace prose-pinning system-prompt tests with a structural sharing check

The two removed tests pinned exact sentences of the default system prompt
('reversibility and blast radius', 'premature abstraction', optional-tool
phrasings that must not appear, ...). They broke on any intentional
wording change while only catching regressions that reused the same words.

The one real contract underneath — shared, ungated sections must render
byte-identically in the root agent and every subagent profile — is now
checked structurally by slicing the section out of the root prompt and
asserting the other profiles contain it, regardless of its wording.

* test: remove wording-pinning tests of model-facing prose across both suites

Sweep of the class identified in #3030: assertions pinning the exact
English wording of product model-facing text (system prompt, reminder
and injection .md files, tool descriptions, shipped profile/skill
bodies). They break on any intentional rewording yet only catch
regressions that reuse the same words.

Across 35 files (~60 test cases, net -1131 lines):
- deleted dedicated wording tests: 'exposes current metadata and
  schema' description pins, goal/plan/todo reminder content tests,
  tower skill-body prose pins, goal-outcome.test.ts;
- trimmed wording assertions from behavioral tests that otherwise
  stand alone; kept identifiers (tool names, XML tags, section
  markers), structural properties (wrapping/escaping/gating/cadence),
  fixture data, tool outputs and error messages;
- re-anchored a few gating tests on exported constants
  (WINDOWS_PATH_HINT, DEFAULT_REPLY_STYLE_GUIDE) instead of prose
  literals.

Deferred for a follow-up decision: ~15 tests whose prose pin is the
only discriminator of which reminder/budget-band fired (constants not
exported). Wire baselines and snapshot machinery untouched.
