Subject: [PATCH 02/15] fix(cli): kill entire process group when stopping fern
 docs dev (#14751)

* fix(cli): kill entire process group when stopping fern docs dev

When fern docs dev is killed, the cleanup only sent SIGTERM to the
direct child node process, leaving Next.js worker processes (next-server)
running as zombies consuming CPU and holding the port.

Fix by:
1. Spawning the Next.js server with detached: true so it runs in its
   own process group
2. Using process.kill(-pid) to kill the entire process group including
   all child worker processes
3. Closing the file watcher during cleanup to prevent resource leaks

Resolves regression of https://github.com/fern-api/fern/issues/7027
Linear: FER-9564

Co-Authored-By: Sandeep Dinesh <sandeep@buildwithfern.com>

* fix: add debug logging to process group kill catch blocks

Co-Authored-By: Sandeep Dinesh <sandeep@buildwithfern.com>

* fix: rewrite cleanup to reliably SIGKILL process group

The previous cleanup had two bugs:
1. serverProcess.killed is set immediately when .kill() is called,
   not when the process actually exits, so the SIGKILL fallback
   check (!serverProcess.killed) always failed
2. Redundant serverProcess.kill() + process.kill(-pid) calls made
   the logic hard to follow

Now cleanup:
- Sends SIGTERM to the entire process group via process.kill(-pid)
- After 2s, checks if the group is still alive via signal 0
- Force kills with SIGKILL if anything survives

Co-Authored-By: Sandeep Dinesh <sandeep@buildwithfern.com>

* use second pass sweep to kill nextjs

* track actual port of next server

* fix(cli): add log rotation for fern docs dev debug logs

Enforce a 100 MB cap on ~/.fern/logs/. On each fern docs dev startup,
the DebugLogger now scans the logs directory and deletes the oldest
.log files until total size is within the limit.

Closes FER-9568

+        Fix `coerce-enums-to-literals: false` not being respected for boolean
+        single-value enums (`type: boolean, enum: [true]`). Previously, boolean
+        enums were always coerced to literals regardless of the setting. Now
+        `getSingleBooleanEnumValue` checks `coerceEnumsToLiterals` consistently
+        with the string enum path.

Subject: [PATCH 11/15] fix(cli): detect header-parameter name collisions in
 validation (#14732)

* fix(cli): detect header-parameter name collisions in validation

Add no-conflicting-parameter-names OSS validation rule to fern check.
Detects when header parameters and query/path parameters on the same
endpoint normalize to the same camelCase name, which causes broken
generated SDK code (Python SyntaxError from duplicate keyword arguments,
TypeScript duplicate interface properties).

The rule reports an error at validation time so the collision is caught
before code generation.

* fix(cli): add camelCase-normalized collision detection for Fern definition validator

+- version: 4.63.4
+  changelogEntry:
+    - summary: |
+        Add `no-conflicting-parameter-names` OSS validation rule to `fern check`.
+        Detects when header parameters and query/path parameters on the same endpoint
+        normalize to the same camelCase name, which causes broken generated SDK code
+        (Python SyntaxError from duplicate keyword arguments, TypeScript duplicate
+        interface properties). The rule reports an error at validation time so the
+        collision is caught before code generation.

Subject: [PATCH 15/15] fix(internal): fetch remote branch before creating
 worktree (#14772)

When a branch name is specified, the worktree-add script now fetches
from origin first. If the branch exists remotely, the local branch is
created with --track so it stays connected to the remote branch instead
of being a disconnected local-only branch.
