Release v3.7.6 (#1803)

* feat(api-keys): add rename support in permissions modal

Add an editable key name field at the top of the permissions modal,
allowing users to rename API keys alongside existing permission settings.

The backend already supported name updates via PATCH /api/keys/:id — this
wires the UI to send the name field and refreshes the key list on success.

Changes:
- Add keyName state and text input to PermissionsModal
- Update handleUpdatePermissions to validate and send name in PATCH body
- Add integration test for rename via PATCH (valid, empty, too-long names)
- Update E2E mock to handle PATCH requests

* chore(release): bump version to 3.7.6

* chore(release): v3.7.6 — merge API key rename feature and sync docs

* chore(release): expand contributor credits to 155 PRs across full project history

- Expanded acknowledgment table from 29 to 53 contributors
- Added 100+ previously uncredited PRs from project inception through v3.7.5
- Moved contributor credits section to v3.7.6 (current release)
- Synced llm.txt version to 3.7.6

* fix: resolve security ReDoS in codex and bugs #1797 #1789

Integrated into release/v3.7.6

* feat: inject fallback tool names to prevent upstream 400 errors (#1775)

* feat: auto-restore probe-failed database to prevent data loss (#1810)

* fix: safely cast inputs to strings before calling trim() to avoid crashes on numeric fields in proxy modal (#1825)

* chore(release): v3.7.6 — final stability patches for production

* test: update expected db probe-failure error message for auto-restore feature

* chore(workflow): mandate implementation plan generation in resolve-issues

* docs(changelog): rewrite v3.7.6 with complete commit-accurate entries

* feat(analytics): add cost-based usage insights and activity streaks

Expand usage analytics to report total cost, per-series cost totals,
API key counts, and current activity streaks using pricing-aware token
calculations.

Also make probe-failed database recovery choose the newest backup by
its embedded timestamp instead of filesystem mtime so auto-restore
selects the intended snapshot reliably.

* fix(mitm): enforce transparent interception on port 443 only

Reject non-443 MITM port updates in the settings API and normalize
stored configuration back to the required transparent interception
port.

Lock the dashboard port field to 443, update the validation copy, and
add integration coverage to prevent stale custom ports from being
accepted or surfaced.

* docs(changelog): update for analytics and mitm features
