fix(agent-evolution-pool-supervisor): resolve all PR review feedback from round 4

Fix all issues identified in review #8361 (commit 1d14de5b):

- Reverted {milestone_name:w} step pattern to quoted-string format
  'the repository has an open milestone "{milestone_name}" with ID
  {milestone_id:d}' — Behave :w only matches word chars and fails on
  quoted strings from the feature file. (Fixes lines 26, 72, 119)

- Reverted {label_name:w} to 'the label name is "{label_name}"' —
  also needed for Type/Automation which contains / (not a word char).

- Removed v3.1.0 entry from step_repo_has_multiple_milestones fixture;
  its earlier due_on date caused earliest-milestone test to fail
  against the asserted v3.2.0/ID 42.

- Restored meaningful assertions replacing assert True:
  * step_supervisor_continues_without_label asserts found_label is None
  * step_supervisor_continues_without_milestone asserts found_milestone
    is None

- Added precondition assertion to step_supervisor_logs_warning_label
  verifying found_label is None before logging warning.

- Fixed hardcoded /app path in agent definition check step to use
  repo-relative resolution via Path(__file__).parent.parent.parent.

+- **Agent evolution pool supervisor BDD step definitions corrected** (#7888 / PR
+  #7922): Reverted Behave step patterns `{milestone_name:w}` and
+  `{label_name:w}` to quoted-string patterns (`"{milestone_name}"`,
+  `"{label_name}"`). Behave's `:w` matcher only accepts word characters
+  (`[A-Za-z0-9_]`) and will not match values surrounded by double-quotes from the
+  feature file, causing `StepNotFound` errors at runtime. Additionally removed
+  `v3.1.0` fixture entry from `step_repo_has_multiple_milestones` that had an
+  earlier due date than `v3.2.0`, which caused the earliest-milestone lookup test
+  to return the wrong milestone. Restored meaningful assertions (replacing
+  `assert True`) in graceful-skip step definitions:
+  `step_supervisor_continues_without_label` now asserts
+  `context.found_label is None`, and `step_supervisor_continues_without_milestone`
+  now asserts `context.found_milestone is None`. Added precondition assertion in
+  `step_supervisor_logs_warning_label` to verify `found_label is None` before
+  logging the warning.
