The duplicate task rows getTasksForProjects deduplicated came from the
LEFT JOIN multiplying when duplicate task_positions rows existed. The new
unique index on (task_id, project_view_id) removes the root cause at the
SQL layer (the migration also runs before serving), so the join can no
longer multiply. Revert getTasksForProjects and getRawTasksForProjects to
their pre-dedup shape.
A task could end up with more than one task_positions row for the same
(task_id, project_view_id): rapid/concurrent creation raced the
check-then-insert paths, and the create path could insert a position that
a triggered RecalculateTaskPositions had already persisted for the new
task. The table had no unique constraint, so the duplicates were stored
silently (#2844).
In the table view this made the LEFT JOIN on task_positions emit the task
twice; getTasksForProjects enriched only the map entry, so the duplicate
slice row kept an empty identifier and rendered as "#N" instead of
"PREFIX-N" (#2725).
- Add a unique index on task_positions(task_id, project_view_id) via a
dedup migration (mirrors the task_buckets fix in 20250624092830) plus the
unique(task_view) struct tag so fresh installs get it too.
- Harden the create path: only queue a position insert when one does not
already exist for the task+view, and dedupe within the batch.
- Dedupe the task slice returned by getTasksForProjects by id, returning
the enriched entry, so duplicate position rows can never surface a task
twice or with a missing identifier.

Adjust test assertions to reflect that projects inheriting archived
state from parents are now correctly filtered out of ReadAll results,
task collections, and search results across all database backends.
Address review feedback: assert exact result counts when ParadeDB is
active. fuzzy(1, prefix=true) broadens matches via edit distance,
returning 6 projects for "TEST10", 14 tasks for "number #17", and
12 projects for "Test1".
ParadeDB fuzzy(1, prefix=true) returns more results than ILIKE due to
edit-distance tolerance on tokenized terms. Adjust assertions to check
containment rather than exact result sets when ParadeDB is active.
The new fixture task #48 (Landingpages update, project 1) needs to
appear in all feature test expected result sets that list project 1
tasks. Also bumps the expected next index in TestTask_Create.
Restrict the AND-joined sub-table filter merging to range comparators
(>, >=, <, <=) only. Equality and negative comparators (=, !=, in,
not in) must remain as separate EXISTS/NOT EXISTS subqueries because
each matching value lives in its own row.
Merging equality filters like `labels = 4 && labels = 5` into a single
EXISTS would produce an unsatisfiable condition (no single row has
label_id=4 AND label_id=5). Merging negative filters like
`labels != 4 && labels != 5` into NOT EXISTS(label_id IN 4 AND
label_id IN 5) would be trivially true.
Also fix the join tracking to use the first filter's join type
(how the group connects to the previous element) instead of the last.
Add task47 variable (with reminders straddling the test window) and new
test cases that verify AND-joined sub-table filters match the same row.
The test "filtered reminder dates should not match task with reminders
outside window" will fail until the fix is applied.
This fixes a bug where tasks which were filtered out by their label would still be shown. That was caused by the way the filter query was translated to sql under the hood.

This allows to configure the used bcrypt rounds and set it to 4 in tests, greatly speeding up the tests. It's not really required to set this to another value but it might be in the future as computers get faster.
This PR adds reactions for tasks and comments, similar to what you can do on Gitea, GitHub, Slack and plenty of other tools.
