feat(store): add atomic find and replace updates - #774

📝 WalkthroughWalkthroughChangesObservation find-and-replace
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The new find-and-replace updates can expand replacement content without a bound before truncation, allowing excessive memory use and making the PR unsafe to merge until this is addressed. The documentation should also be corrected to remove the unsupported field. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

- Around line 2384-2393: Update the replacement logic in the store flow around
p.Find and p.Replace to avoid constructing an unbounded expanded string: use a
bounded replacement that stops after producing enough content for
stripPrivateTags and the MaxObservationLength truncation suffix. Preserve
existing replacement behavior for normal inputs, and add a regression test
covering repeated matches with an oversized replacement.

The change is intentionally one cohesive PR under an approved size exception because the store contract, both transports, and persistence proof share a single behavior boundary.
