fix(analysis): resolve unresolved merge-conflict markers in __init__ (package failed to import)

[joaovictor91123]

Fixes #404

What

src/trinity/analysis/__init__.py on main contains unresolved git merge-conflict markers (<<<<<<< HEAD / ======= / >>>>>>>, six of them). Python can't parse the file:

>>> import trinity.analysis
SyntaxError: invalid character '§' (U+00A7)

so the entire trinity.analysis package fails to import, cascading into a large swath of the suite and red main CI.

Root cause + fix

A three-way merge of recently-landed analysis PRs left a nested conflict in the import block — union_diagnostics, oracle_column (results_table columns), and definition_of_done (SPEC roll-up) each added an import group. All three are legitimate; this resolves the markers keeping all three import blocks.

Verification

import trinity.analysis succeeds; import * works. Full suite: 1726 passed (the only failures are pre-existing report_script/grader_audit subprocess tests that need pip install -e, which CI does — they pass on CI). ruff + mypy clean on the changed file.

Three PRs are waiting on this file

#415, #416 and #417 are all red solely on these conflict markers — none of them touches src/trinity/analysis/__init__.py, so the merge base is their only failing check. #412 is in the same position.

Useful context for whoever merges: five PRs carry this exact fix

This resolution is not contested. #402, #405, #407, #408 and #403 all rewrite src/trinity/analysis/__init__.py to the byte-identical result — every one of them is index 9916618..6865bc2 — the union resolution that keeps all three import blocks (union_diagnostics, oracle_column, definition_of_done) and repairs the stray paren.

#407 / #408 / #403 are already green, because they each touch this file for their own feature and resolved it along the way.

So there's nothing to arbitrate between the competing fixes — there is only one resolution in play. Merging any one of the five repairs main and turns the rest into no-ops on this file. The dedicated fix PRs (#402/#405) are the lowest-risk route since they change nothing else, but a green feature PR that carries the same resolution works just as well.
