Tom Boucher 0f417aa6d0 fix(#3584): the verb owns the count token and nothing else (#3635)
* test(3584): failing-first coverage for Plans-line trailing text

roadmap update-plan-progress preserves trailing text only when the line begins with a
canonical count token. Every other phrasing — including the TBD value the shipped
template itself suggests — is replaced to end-of-line, and a sentence wrapping onto a
second line has its first line deleted, leaving the continuation standing alone so the
roadmap asserts something nobody wrote. Exit 0, updated:true, and the diff reads as a
routine count bump.

These tests fail on that, and pin the arms that must keep working: the template
placeholder is still replaced, the #2853 token-plus-annotation path is unchanged, CRLF is
neither stranded nor duplicated, and a run that leaves the line alone still updates the
Progress table and checkboxes rather than becoming a no-op.

* fix(3584): the verb owns the count token and nothing else

RED proven at 105bdf7c: 7 failures — the preserving cases (freeform prose, wrapped
continuation, TBD, CRLF) failed while the template-placeholder and #2853 token arms
passed on base.

The trailing-text guard fired only when the line began with a canonical count token:
 dropped the rest of the line whenever the
regex's count group did not match. #2853 fixed end-of-line truncation on that one path
only. The in-code comment justified the rest as 'the fresh-template bracketed placeholder
or other freeform guidance, not user prose' — a heuristic that misreads ordinary human
phrasing and destroys even TBD, the value the shipped template itself suggests at
templates/roadmap.md:37.

The sharper failure was the wrapped sentence: only the first line is inside the match, so
the verb deleted line one and left line two standing alone, leaving the roadmap asserting
something nobody wrote — at exit 0, updated:true, in a diff that reads as a routine count
bump.

Inverted the default into three arms. A real count token is rewritten with its annotation
preserved (unchanged, #2853). A bracketed placeholder is detected POSITIVELY and replaced.
Everything else — freeform prose, TBD, a wrapped sentence's first line, an empty value —
returns the match untouched. That last arm resolves the wrapped case by construction: an
untouched first line cannot orphan its continuation.

Positive detection is the load-bearing part. Implemented as 'not a count token, therefore
disposable', rows 1-3 come straight back; the detector instead asks whether the value IS a
bracketed placeholder.

Leaving the line alone does not make the verb a no-op: the phase checkbox, the
Progress-table cells and the plan-checklist row still update in the same run, and that is
asserted. CRLF is unaffected in every arm — the pattern's [^\r\n]* never consumes the
\r, so it sits outside the match regardless of which arm runs.

Fixes #3584

* fix(3584): detect the template placeholder by its text, not by its brackets

Two defects in the arm-2 detector shipped in fc23e49e, both found in review.

Finding A: isBracketedPlaceholder asked only whether the trimmed value was wrapped
in [...]. Brackets are ordinary prose punctuation in a roadmap, so any hand-written
bracketed note — '[Deferred pending re-scope]', '[blocked on #1234]' — was classified
as the fresh-template placeholder and destroyed. That is the very defect #3584 is
about, reintroduced one arm over. The detector now matches the placeholder's TEXT
(/^\[\s*Number of plans\b[\s\S]*\]$/i), so it recognizes the shipped template
value and its short form and nothing else.

Finding B: the count group matched '\\d+\\s+plans' only. The plural is not the
template's own output shape — templates/roadmap.md:62 ships '1 plan' — so a
single-plan phase fell through every arm and its line froze permanently, never
updating again. Widened to 'plans?'. This one was introduced by the arm-3 default:
before it, the singular fell through to the old replace-everything path and at
least stayed current.

Cases 11-14 cover both: a bracketed human note preserved, the short placeholder
still replaced, '1 plan' rewritten, and '1 plan (annotation)' rewritten with the
annotation intact. Verified against the live binary, not just re-read.

Also converted all 15 cases in this block from try/finally to t.after(), per
CONTRIBUTING.md:356-370 which bans try/finally in test bodies. The existing #2853
block above is untouched — it is not in this change's scope and its conversion is
not this fix's concern.

Fixed 3635

Roadmap Plans: lines keep their hand-written text instead of being overwritten with a plan count — roadmap update-plan-progress replaced everything after the Plans: label whenever the line did not already begin with a canonical N/N plans token, silently destroying freeform prose, a TBD note, or a hand-written annotation. A sentence that wrapped onto a second line lost only its first line, leaving the continuation stranded so the roadmap asserted something nobody wrote — at exit 0, in a diff that read as a routine count bump. The count is now written only over a real count token or the fresh-template placeholder, and a single-plan phase (1 plan) is recognized rather than frozen. (#3584)
