The guard tests used 3-char query tokens whose field tokens were literal
continuations ('car'/'carpet'), so the startsWith rule returned 0.9 before
the shared-prefix rule was reached. With MIN_SHARED_PREFIX=4 the rule is
unreachable for any 3-char token, making the assertion impossible to
satisfy. Swapped in cases where neither token is a true prefix of the
other, which actually exercise the guard.

Hand-computing the plan's own test expectations against its own formula
showed four assertions could not pass:
- Body-only matches maxed at 1.0*1/3 = 0.333, below minScore 0.35, so no
low-weight field could ever return a result. The gate now uses the raw
field score; the weighted score only orders.
- The phrase bonus was dead code whenever every token matched, since the
base already saturated at 1.0. Base is now scaled by 0.85.
- Natural-language queries tanked the coverage multiplier; query tokens
are now stopword-filtered.
- 'decide' vs 'decision' is 4 edits apart and unmatchable; scoreToken
gains a shared-prefix rule.

Adds an 11-task TDD implementation plan covering the pure search unit
(tokenize, score, rank, snippet, pipeline), per-service integration for
meetings, wikis, work packages and activities, a recall acceptance
suite, and documentation.
Corrects two errors found while writing the plan:
- The spec's behaviour table named an openproject_search_work_packages
tool that does not exist. searchWorkPackages is a service helper that
only tests call, so ranked work package search would have been
unreachable by any LLM. The plan now registers the tool (18 -> 19) and
leaves openproject_list_work_packages as a pure server-side filter.
- Plan Task 6 originally identified matching agenda items by substring
searching the meeting-level snippet, which cannot work because
snippets are trimmed and ellipsized. Agenda items are now ranked
directly.
